United States' M2 light tank
| A father and son on a M2A2 or M2A3? at Aberdeen: |
Design
The T2E1 was produced after the trials of the T2 and T5 in April 1934. It now had the better vertical volute suspension. It was armed with a .30 and .50 caliber Browning machine guns in the turret, which was the width of the hull. An additional .30 MG was installed in the front of the hull. This vehicle was standardized in late 1935 and put into production at the Rock Island Arsenal and designated the M2A1.8
The T2E2 had 2 turrets installed, with each containing an MG. This was standardized as the M2A2 and put into production in 1938.
Prototype
Production
As a result of the war starting in September 1939, the Ordnance Department rushed to have the M2A4 built. The American Car & Foundry was selected in October 1939 to produce 329 vehicles. The first were delivered in April 1940. The order was increased to 365 and the final vehicles were delivered in March 1941.
