The 37mm anti-tank gun was primarily used in first generation casemates built in 1930-31. The reason for this was that the 47mm gun (Canon AC Mle 1934 47mm) was too big to fit in the casemate firing chambers, which were less than 3 meters deep.

The 37mm anti-tank gun was suspended on a carriage attached to a rail mounted to the ceiling of firing chambers in casemates or infantry combat blocks of ouvrages. This permitted the crew to slide the gun back and forth in order to swap the anti-tank gun for a JM.
Of the several models of 37mm guns issued to the French Army in the 1930’s, the Mle 1934 had the best performance.
