The M116 75mm Pack Howitzer has been in service with the U.S. military since the years following World War I. The relatively light weight and portable towed gun has been an effective weapon for paratroopers, glider-borne infantry, and other highly mobile, rapid response units.

The 75mm Pack Howitzer went through a long evolution, starting as horse drawn artillery, that led to the post-World War II M116:
75mm Pack Howitzer, M1920
75mm Pack Howitzer, M1922A and M1922B
In 1927, the M1922B (with modifications) was standardized as the 75mm Pack Howitzer, M1
In 1930, the USMC adopted the 75mm M1923-E2 to replace its M1897 field guns
In 1934, after further modifications, standardized as the 75mm Pack Howitzer, M1A1
During WW II, the M1A1 was fitted with new wheels and pneumatic tires, called the M8 carriage.
During World War II, the 75mm Pack Howitzer was used in all theaters, especially in rough terrain. The M1A1 with M8 carriage was well suited to parachute delivery and was often air dropped to otherwise inaccessible places. The pack howitzer could be broken down and moved by men or animals in six loads. The Marine Corps used it in this way for supporting landing forces, carrying it ashore disassembled for quick assembly and deployment on the beach.
After World War II, the complete weapon was re-designated Howitzer, Pack, 75mm M116. The 1,340 pound gun has a range of 8800 meters.
