A British Mk IV Tadpole tank somewhere on the Western Front - date and location unknown. This bizarre variant featured a large extension of the tracks aft, between which sat a small open deck and inch Stokes trench motor.
Western front, loading German tank onto railroad flat car. Fewer than a hundred were produced, the only tanks manufactured by Germany that they used in the war. German troops did manage to capture and make use of a number of allied tanks, however.
