Universal Carrier

The Universal Carrier, also known as the Bren Gun Carrier and sometimes simply the Bren Carrier from the light machine gun armament, is a common name describing a family of light armoured tracked vehicles built by Vickers-Armstrongs and other companies.

The first carriers – the Bren Gun Carrier and the Scout Carrier which had specific roles – entered service before the war, but a single improved design that could replace these, the Universal, was introduced in 1940.

The vehicle was used widely by British Commonwealth forces during the Second World War. Universal Carriers were usually used for transporting personnel and equipment, mostly support weapons, or as machine gun platforms.

Design and development
The origins of the Universal Carrier family can be traced back generally to the Carden Loyd tankettes family, which was developed in the 1920s, and specifically the Mk VI tankette.

In 1934, Vickers-Armstrongs produced, as a commercial venture, a light tracked vehicle that could be used either to carry a machine gun or to tow a light field gun. The VA.D50 had an armored box at the front for driver and a gunner and bench seating at the back for the gun crew. The War Office considered it as a possible replacement for their Vickers "Light Dragon" artillery tractors and took 69 as the "Light Dragon Mark III". One was built as the "Carrier, Machine-Gun Experimental (Armoured)", carrying a machine gun and its crew. The decision was made to drop the machine gun and its team and the next design had a crew of three – driver and gunner in the front, third crew-member on the left in the rear and the right rear open for storage. Fourteen of this design were built in mild steel as "Carrier, Machine-Gun No 1 Mark 1" and entered service in 1936. Six were converted into pilot models for the Machine gun Carrier No.2, Cavalry Carrier and Scout Carrier designs – the remainder were used for training.

The carrier put the driver and commander at the front sitting side by side; the driver to the right. The Ford V8 sidevalve engine with four speed gearbox was placed in the centre of the vehicle with the final drive (a commercial Ford axle ) at the rear. The suspension and running gear were based on that used on the Vickers light tank series using Horstmann springs. Directional control was through a vertical steering wheel which pivoted about a horizontal axis. Small turns moved the crosstube that carried the front road wheel bogies laterally, warping the track so the vehicle drifted to that side. Further movement of the wheel braked the appropriate track to give a tighter turn.

The hull in front of the commander's position jutted forward to give room for the Bren light machine gun (or other armaments) to fire through a simple slit. To either side of the engine was an area in which passengers could ride or stores could be carried. Initially, there were several types of Carrier that varied slightly in design according to their purpose: "Medium Machine Gun Carrier" (the Vickers machine gun), "Bren Gun Carrier", "Scout Carrier" and "Cavalry Carrier". The production of a single model came to be preferred and the Universal design appeared in 1940; this was the most widely produced of the carriers. It differed from the previous models in that the rear section of the body had a rectangular shape, with more space for the crew.

Production


Production of carriers began in 1934 and ended in 1960. Before the Universal design was introduced, the vehicles were produced by Aveling and Porter, Bedford Vehicles, Ford of Britain, Morris Motors Limited, the Sentinel Waggon Works, and the Thornycroft company. With the introduction of the Universal, production in the UK was undertaken by Aveling-Barford, Ford, Sentinel, Thornycroft, and Wolseley Motors. By 1945 production amounted to approximately 57,000 of all models, including some 2,400 early ones.

The Universal Carriers, in different variants, were also produced in allied countries. Ford Motor Company of Canada manufactured about 29,000 vehicles known as the Ford C01UC Universal Carrier. Smaller numbers of them were also produced in Australia (about 5,000), where hulls were made in several places in Victoria and by South Australian Railways workshops in Adelaide, South Australia. About 1,300 were also produced in New Zealand.

Universal Carriers were manufactured in the United States of America for allied use with GAE and GAEA V-8 Ford engines. About 20,000 were produced.

Operational history
The Universal Carrier was ubiquitous in all the theatres during the Second World War with British and Commonwealth armies, from the war in the East to the occupation of Iceland. Although the theory and policy was that the carrier was a "fire power transport" and the crew would dismount to fight, practice differed. It could carry machine guns, anti-tank rifles, mortars, infantrymen, supplies, artillery and observation equipment.

United Kingdom
The seven mechanized divisional cavalry regiments in the British Expeditionary Force (BEF) in France during 1939–1940 were equipped with Scout Carriers – 44 carriers and 28 light tanks in each regiment. There were 10 Bren Carriers in each infantry battalion in the same period.

The Reconnaissance Corps regiments – which replaced the cavalry regiments in supporting Infantry divisions after 1940 – were each equipped with 63 carriers, along with 28 Humber Scout Cars.

Universal Carriers were issued to the support companies in infantry rifle battalions for carrying support weapons (initially 10, 21 by 1941, and up to 33 per battalion by 1943 ). A British armoured division of 1940–41 had 109 carriers; each motor battalion had 44.



A British Carrier platoon originally had ten Universal Carriers with three carrier sections of three Universal Carriers each plus another Universal Carrier in the platoon HQ (along with a 15-cwt GS truck). Each Universal Carrier had a non-commissioned officer (NCO), a rifleman and a driver-mechanic. One Universal Carrier in each section was commanded by a sergeant, the other two by corporals.

All the Universal Carriers were armed with a Bren gun and one carrier in each carrier section also had a Boys anti-tank rifle. By 1941, the carrier platoon had increased in strength to contain four carrier sections; one carrier in each carrier section also carried a 2-inch mortar.

By 1943, each Universal Carrier had a crew of four, an NCO, driver-mechanic and two riflemen. The Boys anti-tank rifle was also replaced by the PIAT anti-tank weapon. The Universal Carrier's weapons could be fired from in- or outside the carrier. A carrier platoon had a higher number of light support weapons than a rifle company.

To allow the Universal to function as an artillery tractor in emergencies, a towing attachment that could allow it to haul the Ordnance QF 6 pounder anti-tank gun was added from 1943. Normally the Loyd Carrier – which was also used as a general utility carrier – acted as the tractor for the 6-pdr.

In Motorised Infantry Battalions in the British Army of the Rhine (BAOR) in the early 1950s the Universal was issued one per platoon carrying the Platoon Commander, driver, signaller and the 2-inch Mortar group Nos 1 & 2.

Australia
Universal and the earlier Bren carriers were used by Australian Army units in the Western Desert campaign.

Australian Universal Carriers were deployed to the Western Desert, Egypt during August 1942 serving as command vehicles for the 9th Divisional Cavalry Regiment.

Germany
Captured Universal Carriers were used in a number of roles by German forces.

A total of around sixty Bren No.2 Carriers and Belgian Army Vickers Utility Tractors were converted into demolition vehicles. Carrying a large explosive charge, these would be driven up to enemy positions under remote control and detonated, destroying both themselves and the target. Twenty-nine of both kinds were deployed in 1942 during the Siege of Sevastopol. They achieved some success in destroying Soviet trenches and bunkers, but a significant number were destroyed by artillery. Others were disabled by land mines before reaching their target or were lost because of mechanical breakdowns. A difficulty for the Germans using these foreign-built vehicles was the lack of spare parts.

Variants
The widespread production of the Carrier allowed for several variants to be developed, manufactured and/or used by different countries.

Argentine
An attempted conversion to self-propelled artillery consisting of a single T16 carrier fitted with a six-Model 1968 recoilless gun mount was developed in the late 1960s or early 1970s.

American
American production of the Universal followed the same design as the British Marks I to III
 * Carrier, Universal No.2 Mark I - Ford GAEA engine
 * Carrier, Universal No.2A Mark I - Ford GAE engine
 * Carrier, Universal No.2 Mark II - Ford GAE engine
 * Carrier, Universal No.2A Mark II - Ford GAEA engine
 * Carrier, Universal No.2 Mark III - Ford GAE engine
 * Carrier, Universal No.2A Mark III - Ford GAEA engine
 * T-16
 * The Carrier, Universal, T16, Mark I., initially "Cargo Carrier T16" was the result of US experimentation in 1942 to improve on the Universal for British use and for US in the Pacific war. It was a significantly improved vehicle based upon those built by Ford of Canada, manufactured under Lend Lease by Ford in the United States from March 1943 to 1945. At 155 in it was longer than the Universal with an extra road wheel on the rear bogie; making for a pair of full Horstmann dual-wheel suspension units per side, the engine was a Mercury-division 239 version (GAU370) of the Ford V8 delivering the same power. Instead of the steering wheel controlling the combination brake/warp mechanism, the T-16 used track-brake steering operated by levers (two for each side). The British were supplied with over 3,200 in 1944-1945 but it was considered mechanically unreliable and had less carrying capacity than the Universal. During the war, it was chiefly used by Canadian forces as an artillery tractor. After the war, was used by Argentine, Swiss (300) and Dutch forces.

German

 * 2 cm Flak 38 auf Fahrgestell Bren(e): Single barrel German 2 cm Flak 38 cannon mounted over the engine compartment of a captured Bren carrier.
 * 3.7 cm Pak auf Fahrgestell Bren(e): Captured carrier of 1940, reused by the Germans and fitted with a 3.7 cm Pak 36 anti-tank gun.
 *  Panzerjäger Bren 731(e): Bren carriers captured by the Germans and fitted with a transport rack for three Panzerschreck anti-tank rocket launchers; the weapons were not fired from the Bren gun carrier, only transported.

Italian
In 1942, at the request of the Italian Army (Regio Esercito), Fiat produced a prototype carrier copied from a captured Universal Carrier; it was known as the Fiat 2800 or CVP-4. It is uncertain whether production vehicles were manufactured. Bren carriers captured by the Italians in the field were often fitted with Breda M37 machine guns.

Praying Mantis
The Praying Mantis came from an attempt to produce a low-silhouette vehicle that could still fire over obstacles. A one-man design based on Carden Loyd suspension was not adopted, but the inventor was encouraged to design a two-man version. This version was built in 1943, based on the Universal Carrier. The hull was replaced with an enclosed metal-box structure with enough room for a driver and a gunner lying prone. This box, pivoting from the rear, could be elevated. At the top end was a machine-gun turret (with two Bren guns). The intention was to drive the Mantis up to a wall or hedgerow, elevate the gun, and fire over the obstacle from a position of safety. It was rejected after trials in 1944. An example of the Mantis is preserved in The Tank Museum.
