Description
Propelling Charges M3 (green bag) and M4 (white bag) for the M1 Howitzer are made up in the same way as the M1A1 (green bag) and M2 (white bag) for the old M1917-17A1-18 Howitzers. The M3 is used for the five inner zones of fire and the M4 incorporates five zones in the base charge and has zones 6 and 7 detachable. Since the Ml Howitzer is more powerful than the old weapons, it requires more propellant. The M3 (green bag) Charge is between 14 and 15 inches in length, has a maximum diameter of 5 inches, and weighs 5.94 pounds. The M4 (white bag) charge is between 19 and 21 inches in length, has a maximum diameter of 5.8 inches, and weighs 13.87 pounds.
