Fragmentation grenades
The fragmentation grenade (commonly known as a "frag") is an anti-personnel weapon that is designed to disperse shrapnel upon exploding. The body is made of hard plastic or steel. Flechettes, notched wire, ball bearings or the case itself provide the fragments. When the word "grenade" is used without specification, and context does not suggest otherwise, it is generally assumed to refer to a fragmentation grenade.
These grenades were sometimes classed as defensive grenades because the effective casualty radius of some matched or exceeded the distance they could be thrown, thus necessitating them being thrown from behind cover. The Mills bomb or F1 grenade are examples of defensive grenades where the 30–45 m casualty radius[15] matched or exceeded the 30 m that a grenade could reasonably be thrown.
Modern fragmentation grenades such as the United States M67 grenade have a wounding radius of 15 m (half that of older style grenades which may still be encountered) and can be thrown about 40 m. Fragments may travel more than 200 m.[16]
Concussion grenades
The concussion grenade is an anti-personnel device that is designed to damage its target with explosive power alone. Compared to fragmentation grenades, the explosive filler is usually of a greater weight and volume. The case is far thinner and is designed to fragment as little as possible. The overpressure produced by this grenade when used in enclosed areas is greater than that produced by the fragmentation grenade. Therefore, it is especially effective in enclosed areas.
These grenades are usually classed as offensive weapons because the effective casualty radius is smaller than the distance it can be thrown.
The US MK3A2 concussion grenade is filled with TNT and has a body made of tarred cardboard.
The term 'concussion' is often erroneously applied to stun grenades. This is not descriptive of the effects caused by the grenade. The term 'concussion' is used because the grenade relies on its explosive power to create casualties.
Percussion grenades
French percussion grenade.
A percussion grenade detonates upon impact with the target. Classic examples of percussion grenades are the British Gammon bomb and No. 69 grenade. Timed fuse grenades are generally preferred to hand-thrown percussion grenades because their fuzing mechanisms are safer and more robust than those used in percussion grenades. Some percussion grenades have a conventional pyrotechnic fuse fitted as a backup detonation device.
