Fotogalleri på en M4A2 tank, The Mellemstor tank M4 er langt den amerikanske hærs mellemstore tank, der blev produceret i de største mængder under Anden Verdenskrig. Omkring halvtreds tusind eksemplarer blev produceret under hensyntagen til de forskellige versioner.
Briterne gav ham kaldenavnet "Sherman" med henvisning til navnet på den nordlige general i borgerkrigen. Den amerikanske hær vedtog senere dette kaldenavn, og Medium Tank M4 hedder nu " M4 Sherman " mens sovjeterne kaldte deres "Emcha". Udgave M4A2 : 75 mm svejset diesel GM 6046 (2×6-71 inline)

Den M4A2 was a significant variant of the US M4 Sherman medium kampvogn family, distinguished primarily by its welded hull and the use of a diesel engine.
It was one of the most widely exported models under the Lend-Lease program, especially to the Soviet Union and Great Britain, because its General Motors diesel engine matched the fuel logistics of those nations better than the gasoline engines of other Sherman variants.

Key Distinguishing Features
- Motor: The defining feature is the General Motors 6046 twin diesel engine. This power plant was favored by the Soviets, who ran almost all of their tanks on diesel, making the M4A2 their primary Lend-Lease Sherman variant.
- Hull: Den brugte en welded hull, which gives it a more angular appearance compared to the rounded, cast hull of the M4A1. Early versions featured small driver/co-driver hatches with protruding hoods, while later versions (post-February 1943) adopted a single, improved 47-degree glacis plate with larger hatches set into the roof, eliminating the weak points created by the earlier protruding hoods.
- Bevæbning: The majority of M4A2s were equipped with the 75 mm M3 gun. A later, up-gunned variant, the M4A2 (76)W, was produced with the improved T23 turret mounting the higher-velocity 76 mm M1 gun Og “wet” ammunition storage (hence the ‘W’) for improved crew safety.
Service History
The M4A2 saw very little use in the combat units of the U.S. Army, which standardized on the M4A3 variant with the Ford GAA gasoline engine.
- Soviet Union (Lend-Lease): Nearly 2,000 M4A2s were supplied to the USSR, where they were nicknamed “Emcha.” They were highly valued for their reliability, ease of maintenance, and common diesel fuel.
- Great Britain: The UK was the largest operator, receiving over 5,000 units, which they designated as the Sherman III.
- U.S. Marine Corps (USMC): The USMC primarily used the M4A2 in the Pacific theater, mainly because the diesel engine was less flammable than gasoline, a key concern during island hopping campaigns.
