The artillery piece that could be broken into six mule loads

In short: In the 1920s, the U.S. military faced a logistical nightmare: how to move heavy cannons across jagged mountains and dense jungles. The solution was the 75mm pack howitzer, a weapon designed to be dismantled and carried by animals, paratroopers, or even dropped from planes.

Development of the 75mm pack howitzer began in 1920 to address the need for mobile artillery in difficult terrain. It was officially standardized as the M1 in August 1927. However, due to meager funding, production was initially sluggish; only 32 units were manufactured by 1933, and 91 by 1940. Mass production finally commenced in September 1940, with the M1A1 variant becoming the primary production model. The weapon's defining characteristic was its modularity. The gun tube and breech were joined by interrupted threads, requiring only one-eighth of a turn to connect or disconnect. By dividing the M1 carriage into six separate units for pack animals, each piece weighed from 73 kg to 107 kg. For airborne operations, the M8 carriage variant allowed the gun to be broken into seven mule loads or nine parachute loads, which also included 18 rounds of ammunition.

While primarily a mountain and airborne asset, the howitzer saw diverse roles in World War II. It was issued to U.S. airborne and mountain units, and supplied to allies like the United Kingdom (826 units) and China. It even saw unique service in the Italian SAS, where a single gun nicknamed "Molto Stanco" was airdropped to partisans. Its versatility persisted long after the war, appearing in the Korean War, serving as coastal artillery in the Republic of China, and even being used for avalanche control in western U.S. ski areas.
