75mm M20

The 75mm M20 recoilless rifle is a lightweight, man-portable anti-tank weapon developed by the United States during World War II. It was designed to provide infantry with a potent direct-fire capability against armored vehicles and fortifications, firing a variety of ammunition types.

Developed under the "Kromusit" program to overcome the range and accuracy limitations of early rocket launchers, the M20 officially entered service with the U.S. Army in March 1945, seeing limited action during the final stages of World War II. It achieved its most widespread operational deployment during the Korean War, where it served as a crucial infantry support weapon despite struggling to penetrate the frontal armor of Soviet-built T-34 tanks. The weapon was later utilized extensively during the Vietnam War by both American forces and local allies, while also being copied by China as the Type 52 and Type 56. Phased out of front-line U.S. service in the late 1950s in favor of larger recoilless rifles and guided missiles, the M20 remains in limited use with some secondary military forces worldwide.
