hand grenade M84
Definition/Scope: (FM 3-23.30) Stun hand grenades are used as diversionary or distraction devices during building and room clearing operations when the presence of noncombatants is likely or expected and the assaulting element is attempting to achieve surprise. The components of the M84 diversionary/flash-bang stun hand grenade are: a body that is 5.25 inches in length and 1.73 inches at the corner of the hexagon location. It has a steel hexagon tube with 12 blast and flash release holes along the sides with a heavy steel, hexagon-shaped top and bottom portion. It has a fuse and safety pin (M201A1 MOD 2) which is designed to be nonfragmenting. It has a primary round pull ring and a secondary safety pin with a triangular pull ring. It has a delay time of 1 to 2.3 seconds and it weighs 13.3 ounces. Upon detonation, the M84 generates an intensive heat, a flash of over one million candlepower, and a bang that is 170 to 180 decibels at 5 feet. The grenade can cause disorientation, confusion, ear injuries, and temporary loss of hearing within 9 meters. The flash may damage eyesight and night vision. The M84 is olive drab with white markings, a pastel green band around the middle of the body, and a brown band on the tip end of the safety lever. Caution Use stun grenades as field-expedient early warning devices only when in a combat environment.
