International Legion (Ukraine)

The International Legion of Territorial Defence of Ukraine, or the Ukrainian Foreign Legion, is a military unit of the Territorial Defense Forces of Ukraine composed of foreign volunteers. It was created on 27 February 2022 by the Ukrainian government at the request of President Volodymyr Zelenskyy to fight against the Russian invasion of the country.

Formation of the unit
On 27 February 2022 (three days after the invasion began), under the order by President Volodymyr Zelenskyy, the unit was created to join the defence against the 2022 Russian invasion of Ukraine. Its formation was announced in a statement by the Ukrainian Foreign Minister Dmytro Kuleba. Kuleba promoted the unit on Twitter, inviting individuals to apply and stating that "together we defeated Hitler, and we will defeat Putin too." On 7 March, the Ukrainian Armed Forces released the first image of International Legion soldiers in trenches on the outskirts of Kyiv and announced that new groups were being deployed to the front each day.



Foreign volunteers had come to Ukraine much earlier, in 2014, to join the fight against the pro-Russian separatists as members of Ukrainian volunteer battalions that have been created after the start of the War in the Donbas. Most foreign fighters arrived throughout the summer of 2014, and on 6 October 2014 the Ukrainian parliament voted to allow foreigners to join the Ukrainian military.

While these units have officially been integrated into the Ukrainian Armed Forces, some units such as the Georgian Legion still exercise some autonomy. Prior to the formation of the International Legion, the Georgian Legion was used to train English-speaking foreign volunteers. Kacper Rękawek, a researcher on foreign fighters in Ukraine, believes the majority of Western fighters prior to the 2022 Russian invasion of Ukraine passed through the Georgian Legion.

Other foreign volunteer battalions in the Ukrainian military included the Dzhokhar Dudayev Battalion and Sheikh Mansur Battalion—both formed by anti-Russian and anti-Ramzan Kadyrov Chechens, and the Tactical Group "Belarus" (formed by anti-Lukashenko Belarusians).

While Rękawek said that some foreign fighters that traveled to Ukraine in 2014 held extremist political beliefs and supported the Azov Battalion or the Russian separatist forces in Donbas, the foreign fighters travelling to Ukraine in early 2022 "don't appear to be motivated, as a group, by a certain set of ideological tropes". He also said the mobilization of foreign fighters in 2022 is much larger than the mobilization in 2014. According to Rękawek, the formation of the International Legion was "an attempt to internationalize the conflict via mobilization of Western individuals for the Ukrainian cause. This development would also assist in embarrassing the Western governments, who in the eyes of many Ukrainians are not doing enough to support Kyiv."

Subsequent developments
On 11 April 2023, defense minister Oleksiy Reznikov invited foreign F-16 pilots to join the international legion and fly combat missions for Ukraine, as well as those who know how to maintain Western-made artillery and tanks.

Historical comparisons
Many commentators have compared the International Legion to the International Brigades of the Spanish Civil War,  which comprised foreign volunteers who supported the Second Spanish Republic against the Nationalist faction led by fascist general Francisco Franco that sought to overthrow the Republic.

Other commentators have criticized this comparison. Sebastiaan Faber of Oberlin College in the U.S. argued that depicting the Legion as part of a war between fascism and anti-fascism risks playing "into the Kremlin's narrative, which seeks to portray the "special military operation" as an effort to "denazify" its western neighbor." Critics have also highlighted differences in the makeup of the two international units: volunteers to Spain generally lacked military experience, while those to Ukraine tend to have prior military experience. Moreover, the Brigades were organised by the Communist International, and thus mostly comprised communists with backgrounds in labour movements, whereas the Ukrainian Legion is composed of volunteers from a broader spectrum of ideologies.

Elizabeth Grasmeder of Duke University has compared Ukraine's foreign legion to Finland's efforts to recruit legionnaires and other foreign volunteers during the Winter War (1939–1940). Grasmeder argues states are likely to recruit foreign volunteers when fighting wars of "national survival" against another state attempting to annex their territory. Ukraine's conflict with Russia is an interstate conflict of "national survival" against annexation, as was Finland's with the Soviet Union.

In establishing the force, Ukraine joined more than 90 other nations that have recruited legionnaires and raised foreign legions over the previous two centuries.

A modern day organization that holds the same name and has a similar structure is the Interbrigades, a pro-Russian militia operating in Donbas since 2014.

Recruitment and selection
Early recruitment efforts prioritized former soldiers, especially those with experience in combat. However, regardless of their experience, most of the volunteers who reached Lviv and applied in the early days of the war were accepted.

The First Deputy Interior Minister of Ukraine, Yevhen Yenin, announced in March 2022 that volunteers to the International Legion would be eligible for Ukrainian citizenship, if desired. The necessary probation period is the duration of the war.

As of February 2024, the standard contract length is three years, although soldiers who are not on a combat deployment can terminate their contracts and return home sooner after a minimum service time of at least 6 months. Monthly pay matches enlisted soldier pay in regular Ukrainian units, ranging from approximately $600 per month for rear-line troops to $3300 per month while on a combat deployment.

Selection criteria have broadened since 2022, and now the International Legion accepts those without any experience in military organizations, so long as they demonstrate a willingness to serve. Priority is still given to combat veterans, former military personnel, and other people experienced in relevant fields such as firefighting, medical aid, and law enforcement. Additionally, applicants must be fluent in either English, Spanish, or the Ukrainian language. Applicants must have no criminal record. Candidates receive a physical health assessment before being admitted, which includes an assessment of physical fitness.

Almost all International Legion soldiers receive some amount of training before joining their unit in the Ukrainian military. For those who recently left military service and are thus expected to have a strong foundation of combat skills and drills, only 1–2 weeks of training is required to familiarize them with Ukrainian communications and command structure. For those with less experience, they are put through an expedited form of basic combat training that often lasts up to 6 weeks.

Controversies
Ukrainian Foreign Minister Dmytro Kuleba said that by 6 March 2022 more than 20,000 volunteers from 52 countries had enlisted to fight for Ukraine; several thousand more reportedly joined after the announcement. Kuleba withheld further demographic details, citing that several nations forbid their citizens from fighting for foreign governments. However, a New York Times investigation in March 2023 found that there may be only 1,500 members in the organization, including many who have engaged in fraud and stolen valor. Marco Bocchese, an assistant professor of international relations at Webster Vienna Private University, called the claim of 20,000 volunteers "pure propaganda".

Leadership and criminality
According to The Kyiv Independent, which has received information from sources inside the Legion, the leadership of the intelligence-run wing of the International Legion or GUR is allegedly implicated in various violations, including abuse, theft, and sending soldiers unprepared on reckless missions. The paper also claims that one of the unit's commanders is an alleged former member of a criminal organization from Poland, wanted at home for fraud: the Legion's fighters accuse him of abusing power by ordering soldiers to loot shops, threatening soldiers with a gun, and sexually harassing the legion's female medics.

Members of the Legion, according to The Kyiv Independent, repeatedly reported this to the Ministry of Internal Affairs, the Ministry of Defence, the Verkhovna Rada (Ukraine's national parliament) and the Office of the President of Ukraine, but received no proper answer.

Notable criminals who joined the legion
Prior to the bill allowing for the voluntary mobilization of convicts into the Ukrainian Armed Forces, the International Legion was the only unit that allowed criminals to join its ranks.
 * Craig Lang, an American military veteran and double-murder suspect. He was later extradited back to the United States.


 * Steven Keith Munroe, an American who joined the legion after he was refused entry into the United States army due to his criminal record. He was later killed in action during the 2022 Kharkiv counteroffensive.


 * Tristan Nettles, a 34 year old US Marine Corps veteran who used his girlfriend to unwittingly transport drugs in Thailand.


 * Harusan, a 50 year old Japanese man and former Yakuza member who has been in-and-out jails and involved in numerous crimes. Harusan was sentenced to nine years in jail for violating Japan's explosive substances control law after he had detonated a homemade bomb at the entrance of an organisation that promoted friendly relations between China and Japan. An extra year was added onto his sentence after he beat up a fellow inmate.

Extremism
There have been several reported cases of extremists, fugitives, and criminals from other countries joining the Ukrainian military. A notable case is Craig Lang, an American military veteran and double-murder suspect who served in far-right militias and the legion. In 2022, an image emerged of two Croatian volunteers holding the flag of the Independent State of Croatia. In February 2023, Japanese volunteers posted an image of 4 volunteers posing with the Imperial Japanese rising sun flag. In modern times, the rising sun flag has become a symbol of Japanese Imperialism and has been used by the Japanese far-right. However, the status of the rising sun flag as an indicator of extremism is debatable, particularly since it is still used by some branches of Japanese military such as the Japan Maritime Self-Defense Force who uses a naval ensign that looks similar to the World War II era rising sun flag. The Belarusian Volunteer Corps double cross insignia was noted for being similar to the 30th Waffen Grenadier Division of the SS's insignia. In December 2023, the Ministry of Internal Affairs of Belarus designated the unit as an extremist group. The Karelian National Battalion's first insignia which the unit adopted on 19 January 2023, was a viking ship with a Wolfsangel on the ship's sail. It was later changed to an arm holding a sword with the word "Karelia" above in Karelian. The German Volunteer Corps which was formed in February 2023 was noted by Junge Welt to have connections and similar ideological perspectives to the Neo-Nazi Third Way party. The Russian Volunteer Corps (RVC) was founded in August 2022 The founder and leader of the group is Denis Nikitin, who has been described as a neo-Nazi. The Ukrainian government claims that the RVC is not a part of the Ukrainian armed forces. However, the unit is attached to Military Unit A3449 which is a collection of units of the International Legion that are subordinate to the Main Directorate of Intelligence (HUR).

Recruitment and desertion
Tensions between several countries and the Ukrainian government have been reported because of Ukraine's recruitment of foreign volunteers, due to breaking local laws and several cases of military personnel deserting their units to travel to Ukraine. Citizens of countries with local laws banning service in foreign militaries may face criminal charges upon return to their home country. Countries with military personnel that have deserted and traveled to Ukraine include: Belgium, Britain, France (including legionnaires from Ukraine), and South Korea. The French Foreign Legion has released individual Ukrainian legionnaires from their contract with the beginning of the 2022 Russian invasion.

The legion has experienced desertion. Contracts for foreign volunteers reportedly have indefinite time frames, meaning that volunteers who leave before the end of the war are deserting. It has been reported that the Ukrainian government offers minimal resistance to foreign volunteers who decide to leave.

A legion member from the Faroe Islands named Bjørn told Euronews that of the recruits that end up at the front, 20% leave after 2-5 missions because they realise that "war is hell".

Defection
It was reported in March 2023 that an ex-Legion volunteer named John McIntyre defected to Russia after he was discharged from the legion for bad behavior. He claimed that he wanted to do his part in fighting Nazism.

Strength and organization
Kacper Rękawek, a researcher on foreign fighters in Ukraine, stressed the large number of volunteers announced by Ukraine were "people who applied, who got in touch with the Ukrainian Embassy" and not necessarily the number of foreign fighters in Ukraine.

On 3 March 2022, Zelenskyy announced 16,000 foreign volunteers had attempted to join the International Legion.

On 7 March 2022, Ukrainian Foreign Minister Dmytro Kuleba stated that more than 20,000 volunteers from 52 countries have volunteered to fight for Ukraine. He did not mention the home countries of the volunteers, saying that some of the countries forbid their citizens from fighting for other countries. He also did not specify how many of the foreign volunteers have arrived in Ukraine.

However, investigations in early 2023 by the New York Times and VICE have placed the number of foreign fighters far lower, stating that there were actually only 1,500-2,000 foreign fighters supporting Kyiv. Marco Bocchese, an assistant professor of international relations at Webster Vienna Private University, called the claim of 20,000 volunteers "pure propaganda".

Recruits with past military experience have described the legion as insufficiently officered, leading to unnecessary casualties.

Government acknowledgment of nationals serving in the International Legion
In early March 2022, a French government adviser confirmed a dozen French nationals were in Ukraine and had likely joined the International Legion.

The first photo distributed by the Ukrainian armed forces of the International Legion included members from the United Kingdom, Mexico, the United States, India, Sweden, and Lithuania.

On 9 March 2022, the National Post reported that an anonymous representative of the International Legion of Territorial Defence of Ukraine had confirmed 550 Canadians were in the Canadian Ukrainian Brigade fighting in Ukraine. Belgian Minister of Defence Ludivine Dedonder confirmed on 15 March 2022 that one Belgian soldier had resigned to join the International Legion and another Belgian soldier had deserted to enlist in the International Legion.

Former New Zealand defense minister Ron Mark said that around 20 New Zealanders are fighting for the legion.

List of standalone units
The units and their respective nationalities have been reported as being part of the wider International Legion proper:

Other well-known military units composed by foreign nationals are the Chechen Sheikh Mansur Battalion and 34th Assault Battalion "Mad Pack", the Muslim Caucasian Muslim Corps "Caucasus", the Canadian Black Maple Company, and the diverse Norman Brigade. However, these are not part of the International Legion proper, but are a part of the Ukrainian Ground Forces. These thus serve as affiliated units to the Legion.

Military Unit A3449
Several units of the International legion are subordinate to the Main Directorate of Intelligence (HUR) as part of "A3449", an unnamed military unit. This unit largely consist of the larger, better trained, and equipped members of the legion.

Some units of the Armed Forces of Ukraine also recruit foreign nationals into their ranks, such as the 3rd Assault Brigade and the 25th Airborne Brigade.

Afghanistan
On 2 May 2022, there were reports of Afghan refugees with combat experience in the disbanded Afghan special forces volunteering to fight with assistance from fellow Afghans who can speak Ukrainian and have settled in Ukraine permanently.

On 10 March 2023, most ex-Afghan soldiers trying to volunteer to Ukraine were being turned down out of concern that Wagner may use them to undermine the legion or may be trying to enter Ukraine as a way of traveling further to Europe to escape the Taliban. It was also reported that at least 150 ex-Kta Khas commandos also applied to join the legion.

Albania
Mamuka Mamulashvili, a commander of foreign volunteers in Ukraine, said in an interview with Euronews Albania on 3 March 2022 that there were currently two Albanians in the International Legion. Mamulashvili also claimed they were waiting on the arrival of about 20–30 other Albanian volunteers who have applied to join the war in Ukraine.

Algeria
In early March 2022, the Algerian government called on Ukraine to not enlist fighters from their country.

Argentina
On 13 March 2022, the Ukrainian embassy in Buenos Aires posted on its social media to recruit Argentinian citizens who wanted to join the International Legion. On 22 March, it was reported that an unknown number of Argentinians had signed up to join.

Australia
On 28 February 2022, when asked about Australians volunteering for Ukraine, then Prime Minister of Australia Scott Morrison told reporters "I would counsel against that purely for the safety of Australians that they would not travel to Ukraine," and "I would say at this time the legality of such actions are uncertain under Australian law."

As of 28 December 2022, four Australian volunteers were killed in Ukraine.

Austria
Austrian law stipulates any citizen who enters into the military services of a foreign country has their citizenship revoked. In March 2022, Ministry of the Interior spokesman Harald Sörös confirmed that the government intends to prosecute any violators of the law. When asked whether the law would also be applied to Austrians providing only humanitarian assistance, Sörös responded it was "a matter for the courts to decide, not the executive." Austrian constitutional and administrative lawyer Heinz Mayer argued enforcement of the law could leave Austrians who attempt to join the International Legion or provide humanitarian assistance stateless.

In July 2022, Natalia Frauscher was reported to be the first Austrian volunteer killed in action.

Azerbaijan
On 11 April 2022, an Azerbaijani volunteer was killed fighting in the legion.

Belarus
On 9 March 2022, Euroradio.fm reported that Belarusians in Ukraine had formed the Kastuś Kalinoŭski Battalion with 200 volunteers, named after the Belarusian writer Kastuś Kalinoŭski. The battalion eventually grew to a regiment of over 1000 volunteers. It is not part of the International Legion in order to preserve greater autonomy.

On 30 March 2022, it was reported that more Belarusian volunteers would be assigned to another volunteer unit called the Pahonia Regiment.

Belgium
In Belgian law, it is not illegal for a Belgian citizen to enlist for service in a foreign army. However, Time reported on 7 March 2022 that Belgium was dissuading its veterans from joining the International Legion. The first contingent of seven volunteers left Belgium for Ukraine on 4 March and included two Belgian Turks and a Belgian veteran of the Afghanistan War as well as Eastern European immigrants.

The Ukrainian embassy in Brussels confirmed on 15 March that 18 Belgian residents had arrived in Ukraine to enlist in the international legion while a further 92 had expressed interest in joining. Among those who had made contact with the Ukrainian Embassy were said to be Italian, French, Moroccan, and Luxembourg nationals. At least two members of the Belgian Land Component disobeyed orders to enlist with the International Legion.

It was subsequently reported that two Belgians had been immediately despatched to the front-line while the remainder had been concentrated at Yavoriv military base at the time of its bombing on 13 March. It was subsequently reported on 23 March that "more than half" of the 18 had returned to Belgium, either to convalesce after the Yavoriv bombing or as a result of dissatisfaction with their conditions of service. Concerns were raised about the personal backgrounds and political profile of some of the Belgian volunteers.

According to De Morgen, 14 Belgians travelled to fight in Ukraine between February and June 2022. By this date, nine had returned home and two had apparently been killed in action. One of the two was a 27-year old Belgian Ukrainian called Artem Dymyd from Charleroi who had enlisted in the Ukrainian Army in 2014 and who was killed by rocket fire in Donetsk. One former Belgian soldier named as "Boris" suffered severe injuries.

Brazil
on 5 March 2022, a Brazilian newspaper reported thatabout 500 Brazilians were mobilizing on WhatsApp, Telegram and social networks groups to enlist. The Embassy of Ukraine in Brazil said that "it is not enlisting for the Ukrainian Foreign Legion" or "campaigning to join this military formation". The costs are up to US$1,5 thousand per person, including air tickets and documentation. There are over 600,000 people of Ukrainian descent living in Brazil.

As of 6 July, three Brazilian volunteers were killed fighting in Ukraine. André Hack Bahi was killed on 4 June while helping fellow volunteers escape during fighting in the Luhansk region. Thalita do Valle, a female model and ex-Kurdish Pershmerga volunteer was killed in Kharkiv on 30 June during an attack on a Ukrainian bunker, which also resulted in the death of Douglas Búrigo when he tried to look for her since she didn't evacuate from the bunker in time. Brazilian diplomats confirmed the reports on 5 July.

Bulgaria
A Bulgarian citizen declared he intended to go to Ukraine to join the International Legion, according to the Telegraph newspaper. The announcement was made on Twitter by his acquaintance. According to her, there are other compatriots who also intend to fight in the service of Ukraine.

On 25 September 2022, Bulgarian National Assembly candidate Ivan Kalchev volunteered to participate with the legion in the Ukrainian counteroffensive.

Cambodia
In early March 2022, then Cambodian Prime Minister Hun Sen urged Cambodians not to travel to Ukraine and fight with Ukrainians in the legion.

Canada
The 1937 Foreign Enlistment Act, enacted during the Spanish Civil War, prohibits Canadians from joining a foreign volunteer force against Canada's allies. In March 2022, Minister of National Defence Anita Anand noted that "the legalities of the situation are indeterminate at this time." The government had announced that it is up to individual Canadians to decide whether they want to join and that they "respect personal choices", though the government "is not facilitating" Canadians who are looking to join the International Legion.

Canada is home to the second-largest population of the Ukrainian diaspora after Russia. Due to a high number of Canadian volunteers, a separate Canadian battalion within the Legion, the Canadian Ukrainian Brigade, was established to avoid language barriers and logistics issues. In early March, it claimed that it has recruited at least 600 people. A second formation of Canadian and British volunteers was formed under the name Norman Brigade. It is not part of Ukraine's official International Legion. A former Royal 22nd Regiment sniper nicknamed "Wali" from Montreal, called "Canada's deadliest sniper" after deployments in Syria, Afghanistan and Iraq, also arrived in Ukraine to join the fight against Russia. He returned to Canada after two months.

Some of the soldiers in the Norman Brigade are concerned on whether the Norman Brigade's leader, nom de guerre Hrulf, is incompetent in managing the unit.

Chile
Since early March 2022, there have been reports of volunteers trying to join the International Legion in Ukraine. TVN a Chilean public service broadcaster made an interview with one of the volunteers. Later in March various Chilean media spread the story of Luis Lagos, a former member of the Carabineros de Chile who joined the legion.

Colombia
On 4 March 2022, Colombian newspaper El Espectador reported that at least 50 former Colombian soldiers will join the International Legion in Ukraine. El Espectador managed to get in touch with one of the former Colombian soldiers, identified as Camilo Sánchez, who said in the interview he and the group of ex-soldiers had contacted a Ukrainian military official to enlist.

On 23 July 2022, the first Colombian casualty was an ex-Colombian police officer named Christian Camilo Márquez was killed fighting in Izyum. On 24 July 2023, an ex-soldier named Édisson Giraldo was killed in action.

Costa Rica
On 10 September 2023, ex-Public Force officer Roy Eduardo Rojas Espinoza was killed in action.

Croatia
Croatian law penalizes organizing the departure or going to war in another country if it violates the constitutional order of that country, undermines the territorial integrity of the country and if the person is a mercenary.

Prior to the formation of International Legion, Balkan Insight reported that 20–30 Croatians joined the Ukrainian Azov Battalion to fight in the War in the Donbas in 2014–2015.

Post-formation
On 27 February 2022, Croatian Prime Minister Andrej Plenković commented on news of the possible departure of Croatian volunteers to Ukraine after the announcement of the formation of the International Legion, saying "Every departure to Ukraine is an act of individuals and they take personal responsibility".

On 28 February, it was reported by Dnevnik.hr and Balkan Insight that Croatian fighters were already in Ukraine and more were intending to join them. Some volunteers cited Ukraine's quickness to recognize Croatia's independence in 1991 as a causus belli to join Ukraine.

The Croatian military envoy to Moscow Željko Akrap was summoned to the Russian Defense Ministry on 2 March 2022 and 3 March 2022 over allegations that 200 Croatian volunteers had joined the Ukrainian army. During the second call, the Russian side tried to hand over a protest note to Akrap but he refused to take it.

Cuba
The Embassy of Ukraine in Havana attempted to recruit for the International Legion in March 2022.

Czech Republic
Citizens of the Czech Republic are allowed to join other countries' armed forces as foreign volunteers if they get an approval by the President of the Czech Republic. On 28 February, the president Miloš Zeman stated he would be in favor of allowing potential volunteers to join the newly formed Ukrainian legion. The Ministry of Defence has already reported its first applicants.

It is reported that 600 Czechs have joined the legion as volunteers.

Denmark
Prime Minister Mette Frederiksen said on 27 February 2022, that volunteering was "a choice anyone could make."

On 10 March, the Ukrainian Ambassador in Denmark reported that more than 100 Danes had volunteered.

On 7 April, an anonymous Danish volunteer soldier claimed to have killed 100 Russian soldiers during various operations.

On 26 April, a 25 year old was the first Dane to have been confirmed killed in combat.

Ecuador
The Honorary Consul of Ukraine in Ecuador announced on 8 March 2022, that approximately 850 Ecuadorians had contacted the consulate and the Embassy of Ukraine in Lima attempting to volunteer with the International Legion.

Estonia
The parliamentary groups of Estonia's Riigikogu are currently debating whether to allow Estonian citizens to volunteer to fight for Ukraine.

Minister of Justice Maris Lauri (Reform) said on Monday that Estonian law is unclear in regards to serving in a foreign military and whether doing so is punishable."Based on Estonian laws, nobody can be punished as soon as they go to serve a foreign country," Lauri said. "We don't have a single clause that states that a person should be punished or that they must for example be granted permission or that they must go through some kind of procedure in order to go volunteer."

The justice minister did note, however, that rules exist according to which if someone joins another country's military to fight, then they should inform the state and be granted specific permission to do so. Should anyone go fight on the Russian side, she added, then that is a punishable offense.

"If these are people who are residing in Estonia on the basis of a visa or residence permit, then they simply cannot come back here again," Lauri explained. "And if people come back who received [Estonian] citizenship via naturalization, then they may be stripped of their citizenship."

She added that anyone who has gone to fight who commits war crimes will likewise face punishment.

According to the minister, this matter is scheduled to be discussed at this week's government meeting as well.

On 30 August 2022, President Zelensky awarded German Barinov with the Order of Courage, 3rd Class.

On 7 March 2023, Ivo Jurak, was the first known Estonian volunteer fighter who got killed in the Battle of Bakhmut.

Finland
Finland's Ministry for Foreign Affairs has said that it has no information regarding how many people from Finland have left to join the fight in Ukraine. "The Foreign Ministry's travel bulletin recommends leaving Ukraine immediately. The ministry is highly limited in its ability to assist Finns in the war zone," ministry representatives told Yle in an email.

According to a report by Helsingin Sanomat, the Finnish Defence Forces does not recommend or advise Finns to apply to fight for a foreign cause.

France
Hervé Grandjean, a spokesperson for France's Ministry for the Armed Forces, said individual volunteers could be "integrated in a body of Ukrainian volunteers" and "we cannot prevent them from leaving, (but) nor can we sanction that type of project." However, under French law, France can order a five-year jail term for "mercenaries" who are "specifically recruited to fight in an armed conflict," are neither "from a state involved in the armed conflict" or a "member of such state's military," and who are paid to "participate or try to participate in the hostilities."

A significant response has been reported in France to Zelenskyy's call for foreign fighters, with online interest estimated in the thousands, and some having already gone to Ukraine as of 3 March. The French Foreign Legion prevents current serving legionnaires from serving in Ukraine.

As of 9 July 2022, two French volunteers were killed in action.

Germany
On 2 March, Minister of the Interior Nancy Faeser and Minister of Justice Marco Buschmann declared the Federal Government would not prevent its own citizens from going to Ukraine to fight in the war. These persons also would not face criminal prosecution. This applies to potential missions for both Ukrainians and Russians. The German Federal Police specified they would not let right-wing extremists travel to Ukraine.

Georgia
On 28 February 50 Georgian volunteers arrived in Ukraine. "A group of Georgian volunteers arrived in Ukraine to help the wounded in Ukraine and, if necessary, to take part in hostilities. About 50 people managed to enter Ukraine by crossing the Sarpi customs point. They left for Ukraine on February 28."- Georgian Radio Free reported.

Due to Georgia already having had military conflicts with Russia in the 1992 Abkhazian War and 2008 War, many Georgians sympathized with Ukrainians and therefore went to help. Georgians and Ukrainians have a history of sending volunteers to each other's countries during times of conflict or helping each other in political and humanitarian matters during the aforementioned wars. Georgians have supported Ukraine since the start of the Russo-Ukrainian conflicts. Ukraine has already established a battalion of Georgian fighters called the Georgian Legion since the War in Donbass, but new volunteers would be stationed in the newly formed International Legion of Territorial Defence of Ukraine.

On 1 March, a new batch of volunteers was to fly to Ukraine but the Georgian government canceled their flight. In response, Ukrainian President Volodymyr Zelensky denounced the Georgian government's "immoral position" and has recalled Ukraine's ambassador to Georgia.

Former Georgian Defense Minister, Irakli Okruashvili with some volunteers also traveled to Ukraine and joined the call to arms to defend Ukraine against Russia. His squad then joined the International Legion.

Greece
The Ukrainian embassy in Athens, in early March 2022, received dozens of requests from Greek citizens and Ukrainian diaspora asking for information on how they could join the International Legion.

Hong Kong
The participation of any Hong Konger in the international legion was first officially documented in a thank-you video posted on Twitter on 18 December 2022 by the Ukrainian Ministry of Defence. In that video, the Ukrainian military thanked the 20,000 volunteers from more than 50 countries. Before being deleted, the video featured the national flags of the home countries of the volunteers, including the Black Bauhinia flag of Hong Kong. The black flag is actually not the official flag of Hong Kong but a modified version that was widely used by pro-democracy protesters during the 2019–2020 Hong Kong protests. The gratitude video prompted strong criticism from the Chinese and Hong Kong governments.

Hungary
Sky News reported at least one Hungarian, Akos Horvath, traveled to Ukraine to join the International Legion in March 2022.

India
The Ukrainian Embassy in India tweeted asking Indians to volunteer to fight for Ukraine in early March 2022, but it was later deleted after the Indian Ministry of External Affairs objected. Indian domestic law clearly bars foreign fighters under Chapter VI, Section 121-130 of the Indian Penal Code. Foreign fighters can be sentenced to up to seven years upon return to India.

Over 500 Indians from across the country, including some veterans have submitted applications volunteering to join the International Legion created to fight Russian forces in Ukraine.

However, only one 21-year-old Indian student in Kharkiv is known to have joined the Georgian National Legion in 2022. Later on, the student's family said that the student is willing to leave the Georgian National Legion and return to his home in India.

The first photo of International Legion distributed by Ukraine reportedly showed an Indian volunteer. The Indian volunteer reportedly shown in the photo is believed to be the 21-year-old student who had joined the Georgian National Legion earlier on.

Iran
Sky News reported in early March 2022 that at least one Iranian had traveled to Ukraine to join the International Legion.

Iraq
Oz Katerji, a freelance war correspondent based in Kyiv, tweeted on 1 March that "a group of Kurds have joined the Ukrainian foreign legion" to fight against Russia.

Ireland
Brendan Murphy, an Irish businessman fleeing Ukraine stated in an interview published 2 March 2022 that Irish people had already arrived in the country to fight with the International Legion. He said: "The first Irish veterans – they have to have military experience – arrived in Ukraine last night, which is good to see because they have the Irish tricolor on their arm".

Rory Mason was the first Irish volunteer killed in the Kharkiv region in late September or early October 2022. In late April 2023, Finbar Cafferkey was killed fighting in the Battle of Bakhmut.

Israel
Ukrainian initiatives to recruit Israelis began on 26 February in tandem with thousands of Israelis protesting against the 2022 Russian invasion of Ukraine.

Many protesters had connections to Ukraine or other post-Soviet countries, but also a significant contingent of Israelis attended with no connection to the former USSR at all.

The Ukrainian Embassy focused on recruiting Israelis through its Facebook page.

By early March, it was reported that Israelis had been recruited and were heading to Ukraine. Most were veterans of the Israeli Defense Forces (IDF), and were primarily of Ukrainian, Russian, or other former USSR roots, but not exclusively so, with recruits of Druze Israeli and American-Israeli backgrounds also noted.

On 25 March, it was reported by the Israeli national newspaper Yedioth Ahronoth that a group of former IDF soldiers were training Ukrainian civilians; the ex-commando in charge stated to journalists that the program originated as a rescue mission for Ukraine's Jewish population but changed as the Ukrainian Jews required armed escorts and then military training. Yedioth Ahronoth reported that an unidentified Israeli official stated that the Israeli defense establishment was "looking the other way", in part because of the increasingly pro-Ukrainian sentiments and growing suspicion toward Russia, the official himself noting his own solidarity toward Ukraine in the face of "the worst kind of Russian aggression".

The 1998 Regulation of Foreign Military Assistance Act was passed to "regulate the rendering of foreign military assistance" by South Africans, but was largely referred to as a "mercenary bill" targeting former apartheid soldiers working as mercenaries. The 2006 Prohibition of Mercenary Activities and Regulation of Certain Activities in Country of Armed Conflict Act amended the bill, but appears to have never been enforced.

On 11 March 2022, Ukraine's ambassador to South Africa, Liubov Abravitova, announced she is waiting on a legal ruling from the Department of International Relations and Cooperation on whether or not Ukraine may actively recruit South Africans to join the International Legion. Abravitova told the Cape Town Press Club, on 11 March, that anyone who wanted to join Ukraine's fight against Russia was welcome. She added that Ukrainian President Volodymyr Zelensky's idea was not new since France already had a foreign legion.

On 20 May, Rhee was reported to be injured in the field, but is expected to make a recovery when he goes back to South Korea. Rhee mentioned that he's willing to be investigated by the police over his presence in Ukraine and has politely turned down Ukrainian nationality. The Seoul Metropolitan Police Agency is in the process of adding his name to a no-fly list.

On 18 June 2022, the South Korean government is checking claims that four South Korean nationals are killed in action fighting with the legion. The report also mentioned that 13 South Koreans are working in the legion.

"The government fully understands the sentiment of its nationals who want to stand for righteousness and give their support to Ukraine. However, on the standpoint of protecting the safety of its people and the risk of war, the government advises its nationals to avoid going there." and reiterated "in order to urge Russia to stop its military aggression against Ukraine, Taiwan will participate in the economic sanctions imposed on Russia along with the international community."

Due to the lack of formal diplomatic relations between Ukraine and Taiwan, no diplomatic missions were established in either side. The Representative Office of Poland in Taipei suggested that the Taiwanese volunteers first need to travel to Poland, and enlist with the Ukrainian Embassy in Warsaw, but the Polish Office in Taipei declined to comment when the press tried to verify, neither confirm nor deny that such information is held.

On 22 March, a Taiwanese Amis volunteer named Wang Jui-ti traveled to Helsinki to hand his application to join the Legion. On 29 March, he said that the application was not successful because the legion changed its requirements for volunteers to have military experience with combat exposure. However, he was advised by Ukrainian embassy staff in Vilnius, Lithuania to instead help the refugees in Poland.

On 10 April, it was reported that a Taiwanese man named Wang Nan-ying (known as Naive Wang), who lived in Kharkiv for eight years, enlisted in the legion after the war started while helping refugees in Poland. He is fluent in Ukrainian and Russian aside from English, Japanese and Mandarin.

Turkey does not have a law that bars foreign fighters, but frequently prosecutes them upon return to Turkey for violating criminal or anti-terror laws. The Turkish authorities have not commented on Turkish citizens joining the war in Ukraine.

Turkish news reports have confirmed some Turkish citizens and members of the Turkish diaspora had attempted to join the International legion. Some Turkish nationals in Ukraine have been turned away from the International Legion.

A Turkish citizen who has been living in Ukraine said he had signed up for the foreign legion along with 6 other Turkish citizens but they were later rejected. He claimed that the Turkish authorities had asked Ukraine not to accept any Turkish citizens into its Foreign Legion.

United Kingdom
In February 2022, Liz Truss, then Foreign Secretary of the United Kingdom said: "The people of Ukraine are fighting for freedom and democracy, not just for Ukraine but also for the whole of Europe because that is what President Vladimir Putin is challenging. And absolutely, if people want to support that struggle, I would support them in doing that." However, then prime minister Boris Johnson's office did not endorse Truss's statement. The statement was also criticized by several politicians who said volunteers may be in violation of the Foreign Enlistment Act 1870. It has been reported those who travel to Ukraine may be acting in contravention of UK anti-terrorism laws, though legal experts said prosecution would be unlikely owing to the UK government's support for Ukraine's armed resistance.

Ukrainian sources said 6,000 Britons had registered an interest in joining. The Times reported that over 150 former paratroopers who served in the War in Afghanistan had joined and were travelling to the front line.

United States
The United States Department of State issued a travel advisory formally advising all Americans not to travel to Ukraine. 18 U.S. Code § 960, the modern and binding form of the Neutrality Act of 1794, prohibits United States citizens from taking up arms against any country at peace with the United States. It is unclear whether the United States Congress will pass legislation to waive this restriction with respect to the conflict in Ukraine. However, several Americans have spoken publicly and in the media about their service in Ukraine, without any legal charges filed against them.

On 3 March 2022, the Ukrainian embassy in Washington, DC announced that 3,000 U.S. citizens had signed up to volunteer.
