Description:
Hand grenade MK32A2 is about the same size as the fragmentation hand grenade, but has a cylindrical body made of pressed fiber. The shape of the fuze safety lever is slightly different from that of a fragmentation grenade and conforms to the shape of the body of the grenade. The MK3A2 may be issued fuzed with or without safety clips, or unfuzed. The grenade body is a cylinder made of pressed fiber and contains high explosive TNT. Hand grenade fuzes M206A1 or M206A2 are pyrotechnic delay detonating fuzes. They differ only in body construction. The body contains a primer and a pyrotechnic delay column. Assembled to the body are a striker, spring, safety lever, safety pin with pull ring, and a detonator assembly. The split end of the safety pin has an angular spread or diamond crimp. The hand grenade safety clip is designed to keep the safety lever in place, should the safety pin be unintentionally removed from the grenade. It is an additional safety device used in conjunction with the safety pin. Safety clips, of spring steel wire, consist of a loop, which fits around the threaded section of the fuze, and a clamp, which fits over the safety lever. Because the loop fits around the threaded section of the fuze, the clip must be assembled to the grenade when the fuze is assembled to the grenade.
Use:
An offensive hand grenade similar to hand grenade used for blast effect or demolition purposes.
Functioning:
Release of the safety clip and removal of the safety pin permit 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 axis and strikes the percussion primer. The primer emits a small, intense spit of flame, igniting the delay element. The delay element burns 4 to 5 seconds, then sets off the detonator. The detonator explodes, thus initiating the explosive charge. When the filler detonates the force of the explosion is dissipated mainly in the form of shock waves rather than high velocity.
