The AC 47 was a French anti-tank gun of 47 mm calibre. It was principally used in the: ouvrages and casemates of the——Maginot Line in the late 1930s; another version was created for naval use.
The AC 47 was principally used as a defensive weapon, since its portability was intentionally limited to prevent the "weapon from being turned on defending troops if a fortification was captured."
