Famous for defeating T-34/85 tanks in Korea, the M20 “Super Bazooka” found virtually no tanks to fight in Vietnam. However, its 3.5-inch rockets were good at blowing holes in enemy fortifications.

For U.S. forces, the M20 gave way to the M72 LAW and the M67 recoilless rifle early in the war. (AP Photo/Merron)
