M4 Sherman was the most popular American tank of World War II. Between February, 1942, and June, 1945, a total of 49.000 units of all versions were produced. Dozens of variants of M4 tanks were created. They differed in the method of hull production (welded, riveted, casted) as well as turret, main armament and additional equipment. Several special versions were also made (especially for the needs of the Normandy landing in 1944): the floating Sherman DD (Duplex Drive), Sherman Crab (with anti-mine trawl), Sherman Dozer (with bulldozer at the front – for demining and engineering tasks), Sherman Zippo (Sherman with a flamethrower mounted instead of the main gun).
