 The Brandt 60mm LR gun-mortar was developed directly from the Brandt Mle CM60A1 and retains the same falling block breech mechanism reminiscent of direct fire artillery.The firing pin is automatically withdrawn when the breech is unlocked, reducing the potential for misfire.Like its predecessor, it can be either muzzle-loaded or breech-loaded and was designed to be mounted in the turrets of armored fighting vehicles.
