The M56 was the heaviest of the US military 81mm types used during WWII, with an overall weight of 16 lbs with a maximum range of 1,300 yards. The round was effective against both personnel and materiel in the field. It is used against dugouts, barricades, and underground structures where a mining action is desired. This shell is a much more effective one than the M45 due to the fact that it contains approximately 40 percent explosive filler as compared to 30 percent explosive filler of the M45. The greater the percentage of explosive filler, without sacrificing the penetrating ability of the shell body, the more effective is the shell when used for mining effect.

The shell measures roughly 22¾” and has a 1953-dated fuze. A great piece perfect for any ordnance collection.
