Rifle Grenade

The Rifle Grenade is an explosive launched from the muzzle of a rifle.

Battlefield 1942: Secret Weapons of World War II
The expansion to Battlefield 1942 adds the Mauser K98k Gewerhgranate, a Kar98k with a rifle grenade.

Battlefield 1943
The Rifle Grenade is a secondary weapon issued to the USMC (M17 variant) and the IJN (Type 91 variant) "Rifleman" kit. It is very powerful against infantry, usually killing in one shot with its very effective detonation radius. It can also be used against vehicles, being able to destroy a jeep within 1-2 shots, but using it against a tank is highly unrecommended unless said tank is heavily damaged.

An interesting feature about the rifle grenade is that switching to the weapon immediately mounts the explosive (in less than a second) instead of manually placing it like when a player reloads the rifle grenade.
