菱形戦車 マークI戦車
The Mark I Tank was the first [[tank]] to enter production during [[World War I]]. Rhomboidal in shape and bearing weapons in sponsons on either side of the armored hull, it was designed to break the stalemate of trench warfare. The Mark I in particular included a pair of large wheels behind the tank to aid steering, although these proved unsuccessful and were later dropped.
