The best known of all American tanks, the Sherman M4A2 was designed in 1941 as an improvement on the earlier Lee and Grant medium tanks. The Sherman embodied the results of careful study of tank warfare in the first years of World War II.
The 'female' version of the MkI tank was produced in larger numbers than it's 'male' partner due to the fact that the four Vickers machine guns mounted on the sides were found to be more effective in combat than the heavier guns carried by the 'male' in the trecherous conditions on the Western Front.
The Rocket Launcher T34 (Calliope) was a tank-mounted multiple rocket launcher used by the US army during WWII. The launcher was placed on top of the tank, and fired a barrage of 4.5inch (114mm) rockets from 60 launch tubes. It adopts its name from the musical instrument "Calliope", also know as the steam organ.
The Cromwell, official name Cruiser Tank MkVIII, was one of the most successful British tanks of the Second World War. Named after the English Civil War leader Oliver Cromwell, the tank proved to be an adept and rugged fighting machine and served until the end of the war.
The Tiger I was produced from late 1942 as an answer to the formidable Soviet armour encountered in the initial months of Operation Barbarossa. The Tiger I design gave the Wehrmacht its first tank mounting the 88mm gun. During the course of the war, the Tiger I saw combat on all German battlefronts.
