: Medium Tank

## [General information](/md/rv/vehicles/m4a3-105.md#general-information)

Description
: The **M4A3 (105)** is a Medium Tank variant of the American **M4 Sherman** armed with a 105 mm howitzer for infantry and fortification support. The M4A3 series used the **Ford GAA** gasoline V8 and was the principal variant supplied to U.S. Army units in the latter part of the war; the 105 mm M4 howitzer version saw use in the Pacific and in Europe for bunker-busting and indirect fire. The vehicle weighs 31.7 tonnes and is crewed by five: driver, gunner, bow gunner, commander, and loader. The **Ford GAA V8** produces 500 horsepower for a 15.8 hp/t power-to-weight ratio and a top speed of 42 km/h.
Main armament is the **105 mm M4** howitzer with HE and HEAT-type rounds, backed by a coaxial **.30 cal M1919**, a cupola **12.7 mm M2**, and a bow **.30 cal M1919**. The commander and bow gunner positions have stabilizers; the gunner uses a 3x telescope and a 1x/6x periscope with no rangefinder.
