M116 howitzer

The 75mm pack howitzer M1 (redesignated the M116 in 1962) was a pack howitzer designed in the United States. The gun saw combat in World War II with the United States Army (primarily in airborne units) and the United States Marine Corps, and was also supplied to foreign militaries. Initially designed to be moved across difficult terrain, the gun and carriage could be broken down into several pieces to be carried by pack animals, and this ability as well as its compact size allowed it to be used by paratroop and glider forces. In addition to the pack or air-portable configuration, the gun was also mounted on a split-trail carriage to serve as a field artillery piece. The M1 in its original version was mated to a number of self-propelled carriages, though only one of those – 75 mm HMC T30 – reached mass production, while the M2 and M3 variants were vehicle-mounted in the 75 mm HMC M8 and some LVT models.
