Anti-personnel Fragmentation Grenades
Anti-personnel fragmentation grenades (AP frag grens) are weapons that is designed to disperse lethal fragments upon detonation. The body is generally made of a hard synthetic material or steel, which will provide some fragmentation as shards and splinters, though in modern grens a pre-formed fragmentation matrix is often used. The pre-formed fragmentation may be spherical, cuboid, wire or notched wire. Most AP grens are designed to detonate either after a time delay or on impact.
When the word grenade is used without specification, and context does not suggest otherwise, it is generally assumed to refer to a fragmentation grenade.
AP frag grens can be divided into two main types, defensive and offensive, where the former are designed to be used from a position of cover, (eg. in a slit trench or behind a suitable wall,) and have an effective radius greater than the distance it can be thrown, while the latter are for assaulting troops and have a smaller effective fragmentation radius.
Modern fragmentation grenades such as the United States M67 grenade have a wounding radius of 15 m (half that of older style grenades, which can still be encountered) and can be thrown about 40 m. Fragments may travel more than 200 m.
