The M26 is a fragmentation hand grenade developed by the United Statesmilitary. It entered service around 1952 and was first used in combat during the Korean War. Its distinct lemon shape led it to being nicknamed the "lemon grenade" (compare the Russian/SovietF1 grenade, with similar nickname).
The grenade was developed as a result of studies on the Mk 2. The M26 series was created after World War II to meet criticisms of the Mk 2. It was replaced by the M33 series grenade (M33/M67) at the end of the Vietnam War.
