The rate of fire was 3-to-6 rounds per minute, depending on the hustle of the gun crew. It had a muzzle velocity of 1,250 feet-per-second, which sounds low but keep in mind this was for a 14.7-pound shell. The M116 required a crew of six and could fire a shell up to 9,500 yards– a little over 5 miles. Pieces weighed between 160- and 235-pounds each. Typically referred to as the “Pack Seventy-Five” the gun was designed so that it could be broken down into several pieces to be carried by pack animals such as mules. Having a total weight of just 1,340-pounds when combat-ready, it was light enough to be towed by a truck or jeep, however, that is not its best attribute.

It met a need for a compact artillery piece that could be moved across difficult terrain, replacing the 1900s-era Vickers Mountain Gun previously used for that purpose. The 75mm M116 Pack Howitzer was designed in the United States in the 1920s.
