119's "Armored" Edges

The St. Chamond has a larger gun, however, I am going to give this win the Mark IV for the following reasons: the Mark IV has a larger area covered by the twin sponson guns than the the single fixed gun, and it his slightly heavier armor. Not to mention, the St. Chamond was notorious for getting the portruding "nose" section stuck in trenches. While the St. Chamond was largely a failure, the Mark IV did see some success, most notably at Cambrai.

Overall Winner: Mark IV Tank.
