Also known as: 小銃擲弾
A specialized type of grenade that uses a Rifle-based launcher rather than being thrown by hand. Some of them look similar to Mortar Shells. Rifle grenades are attached onto the muzzle, and propelled by a blank cartridge inserted into the chamber of the Gun.
Modern use of rifle grenades has been widely phased out in favour of Underbarrel Grenade Launchers.
