M67 Grenade

The M67 fragmentation grenade is a small hand-held anti-personnel weapon designed to be thrown, which then explodes after a short time. The word "grenade" is derived from the Old French (pome) grenate ("pomegranate"), in reference to the general size of early grenades, and because its shrapnel pellets reminded soldiers of the seeds of this fruit. Real grenades have a casualty radius of 15 meters, but the range is shorter in-game for balance. Players near a grenade on the ground have the option of throwing it back, although this is never done in real life under any circumstances due to the high chance of there being little time on the fuse left and the increased area of effect of a mid-air detonation. Instead, troops are trained to run from the grenade, go prone and face their helmets towards the grenade. Troops not wearing helmets will instead take cover or get as far away from the grenade as possible.

Grenades are filled with explosive content, or filler. Five seconds after the safety spoon is released, the filler is ignited and the grenade explodes. Some users release the spoon before throwing the grenade, which is called cooking. This is dangerous, however, as fuse lengths are inconsistent.
