First seeing action in 1917 as an evolution of the Mark I tank, the Mark IV was the most widely produced tank of the First World War. Consisting of two variants, the Male, armed with two 6pdrs and three machine guns, and the Female, armed with five machine guns, this tank was designed as a linebreaker. The Mark IV was employed primarily by the British, but also in smaller numbers by Germany (as 'beutepanzers') and the U.S. 
 
Includes both the Male and Female variants of the tank. These pieces are interchangeable and have 5x2mm holes for magnets.  Also includes a trench crossing 'crib'.
