The 105 mm Howitzer M3 was a U.S. light howitzer designed for use by airborne troops. The gun utilized the barrel of the 105 mm Howitzer M2, shortened and fitted to a slightly modified split trail carriage of the 75 mm pack howitzer.

The howitzer was used by the U.S. Army during World War II. It was issued to airborne units and the cannon companies of infantry regiments.

June 25, 1950

More than half of the troops in the original North Korean People’s Army (NKPA) were veterans of the victorious Chinese Communist forces in the Chinese Civil War. Weapons and equipment, all the way from T–34 tanks to Tokarev pistols, had been made available by the Soviet Union; and Soviet instructors prepared the invading army for its surprise attack of 25 June on the Republic of Korea.[2]

  There could have been little doubt as to the outcome. Although the ROK army included eight divisions and a regiment, estimated at some 98,000 men in all, it could not compare with the NKPA establishment of about equal numbers. The difference lay in the purposes for which the two forces had been organized during the joint Soviet-American occupation of Korea after World War II. While Red Army officers created the NKPA as an  instrument of aggression, American instructors trained the ROK troops for frontier defense and internal security.

  They had neither tanks nor combat aircraft, and their heaviest artillery consisted of a few battalions of 105mm M-3 howitzers. It was scarcely more than a lightly armed constabulary which crumpled at the first shock of NKPA columns led by Soviet-made tanks and supported by Soviet-made bombing planes. The four ROK divisions deployed along the frontier were routed, and Sŏul fell to the invaders on the third day.
