US Cartridge, 81mm Training, M68
This cartridge is used for training in the loading and firing of the 81mm mortar.
Unlike other mortar ammunition, the components of this round are issued separately to facilitate replacement of damaged, worn, or expended parts. The complete round consists of an inert projectile, a fin assembly, and an ignition cartridge. The pear-shaped, cast iron projectile has no provision for a fuze and is internally threaded at the base to accept the fin assembly.
Nothing else to see.
