rifle grenade

A rifle grenade is a grenade launched from a rifle or carbine using a special cartridge. While hand grenades are limited by throwing distance, rifle grenades extend this range by being launched from a weapon.12

Grenades themselves are small bombs, often resembling pomegranates in shape, and have been used since the 15th century. They became particularly important in trench warfare during World War I, making them standard infantry equipment. Rifle grenade launchers, developed in the 1950s, could propel a 40-mm grenade up to 400 yards, bridging the gap between hand-thrown grenades and mortars.32
