107mm B-11

The 107mm B-11 is a heavy recoilless rifle developed by the Soviet Union in the early 1950s. It was designed primarily for anti-tank and anti-personnel roles, often mounted on a two-wheeled carriage for mobility.

Designed by the Special Design Bureau No. 4 under Boris Shavyrin, this weapon was developed to provide Soviet motorized rifle and airborne troops with a highly mobile, heavy anti-tank capability capable of defeating Western armor of the early Cold War. It officially entered service with the Soviet Army in 1954 alongside the smaller 82mm B-10 recoilless rifle. The weapon was widely exported to Warsaw Pact allies and North Vietnam, seeing extensive combat use during the Vietnam War, the Six-Day War, and various proxy conflicts in Africa. While largely replaced in front-line Soviet units by anti-tank guided missiles during the 1960s and 1970s, the B-11 remains in active service with several developing nations and non-state actors due to its rugged reliability.
