US Cartridge, 81mm Training, M445 (T32E1)
This cartridge is used for training loading and firing of the 81mm mortar.
Unlike other mortar ammunition, the components of this round are issued separately. This facilitates replacement of damaged, worn, or expended parts. The complete round consists of a projectile body, a training fuze, and a fin assembly designed to hold an ignition cartridge and a smoke cartridge. The projectile is internally threaded at the nose to accept the training fuze, and externally threaded at the base to accept the fin assembly.
Nothing else to see.
