Operation 1107

Operation 1107 (Burmese: ၁၁၀၇ စစ်ဆင်ရေး) is an ongoing joint military operation launched on 7 November 2023, by the Karenni National People's Liberation Front, Karenni Army, and Karenni Nationalities Defence Force against the Tatmadaw military junta in Myanmar, during the Myanmar civil war. It was launched in support of the concurrent Operation 1027 by other rebel forces in Myanmar.

November
It began on 7 November 2023, with junta border posts in Mese Township, Kayah State (including Pantein) being seized by Karenni forces. Many weapons were seized by the rebels. 70 junta soldiers were said to have been killed in the attack, while Karenni forces claimed to have incurred four dead. Starting from 4:00 AM on the 11th, KNDF and KA forces started attacking military bases around Loikaw in an operation dubbed "Operation 11.11". The coalition forces captured seven military bases and shot down an aircraft.

The KNDF claimed responsibility for the junta K-8W trainer/attack aircraft which crashed in a combat zone near Loikaw, the capital of Kayah State. However, the Tatmadaw claimed the aircraft suffered a technical problem. A junta source stated that it was unclear if it crashed from enemy fire or from technical failure.

December
In addition to Loikaw mentioned above, fighting has been reported in Demoso and Mobye. It was also stated that this fighting has strategically prevented Tatmadaw from sending reinforcements from Kayah State to Shan state, where Operation 1027 is ongoing. Not only that but also forced it to defend Loikaw and thus left some other areas around it lightly defended.

KNLA also began fighting for Kyaukkyi Township in the Bago Region joined by the Bago PDF. This was a significant development because the township lies outside of Kayah State. On 4 December, KNLA and local PDF units captured the town of Mone in Kyaukkyi Township, marking the first capture of a settlement in Bago Region.

On the 5th, there were reports of initial progress in the Bago region and that 1,500 fighters were involved against Tatmadaw.

On the 9th, Pyu Township was also reported to be under attack by insurgents. Pekon Township that neighbors Kayah State, but is in Shan State is also seeing fighting, with Demoso and Loikaw continuing seeing combat.

On 13 December, reports emerged of insurgents making some initial progress in Pyu Township, where they seized positions along the Yangon-Naypyitaw-Mandalay highway, which is located a few kilometers from the strategically important Yangon-Naypyitaw-Mandalay Expressway. Pyu township is also important due to its close proximity to the capital city Naypyitaw. Involved in this push are the local PDF units as well as KNU, Bamar People’s Liberation Army and KNLA. Fighting in Kyaukkyi Township also continues.

As of December 15, fighting in Mobye is continuing, the insurgents claim to have taken 75% of the town. At least 5 civilians where reported to have been killed as a result of the fighting, with much of the town abandoned by the civilians. The casualties of fighting in Mobye include 11 Tatmadaw and 9 Insurgents soldiers killed.

January
Fighting has been continuing in Demoso as well as the surrounding countryside. Such as in Moso, Hpruso. Al Jazeera reported that this fighting in Moso was linked to a supply road used by the resistance, with Tatmadaw trying to disrupt its use.
