n. a grenade that is thrown from a launching device attached to the barrel of a rifle
Wikipedia
A rifle grenade is a grenade that uses a rifle-based launcher to permit a longer effective range than would be possible if the grenade was thrown by hand.
The practice of projecting grenades with rifle-mounted launchers was first widely used during World War I and continues to the present, with the term "rifle grenade" now encompassing many different types of payloads including high explosive, fragmentation, and anti-tank warheads as well as concussion, smoke, incendiary, and flare missiles.
Rifle grenades have largely been supplanted in the infantry fire support role by a combination of grenade launchers (typically affixed to rifles) and disposable anti-armor rockets.
