Developed in 1915 by the Schneider company, then the largest French armoury, under powered, too heavy and had narrow tracks. The fuel tank was mounted on top of the fuel pump and were very liable to catch fire.
French soldiers called it "rolling crematorium". The 75 mm rapid-fire gun had only a very limited range of fire.
It had a boat-shaped bow with a boom to clear wire entanglements.
