Description
The TH3 incendiary hand grenade AN-M14 is used primarily to provide a source for intense heat to destroy equipment.
The TH3 incendiary hand grenade generates heat to 4000°F. The grenade filler will burn from 30 to 45 seconds. The grenade body is of thin sheet metal and is cylindrical in shape. It is filled with an incendiary mixture, Thermite TH3 and First-Fire Mixture VII.
Hand grenade fuze M201A1 is a pyrotechnic delay igniting fuze. The body contains a primer first-fire mixture. Assembled to the body are a striker, striker spring, safety lever and safety pin with pull ring. The split end of the safety pin has an angular spread.
Safety clips are not required with these grenades.
Functioning
Removal of the safety pin permits release of the safety lever. When the safety lever is released, it is forced away from the grenade body by a striker acting under the force of a striker spring. The striker rotates on its own axis and strikes the percussion primer. The primer initiates the first fire mixture. The fuze delay element, ignition mixture, and grenade starter mixture and filler are initiated in turn by the preceding component.
