The M67 grenade is a fragmentation hand grenade used by the United States Military and Canadian Forces, where it is referred to as the C13. The M67 is a replacement for the M61 grenade used during Vietnam and the older Mk 2 "pineapple" grenade used since World War II.

Composition[link]

The M67 Grenade has a spherical steel body that contains 6.5 ounces of Composition B explosive. The M213 fuse is specifically designed for use with the M67 fragmentation grenade. The M67 grenade weighs 14 ounces in total and has a safety clip to prevent the grenade from detonating accidentally.

Description[link]

The M67 can be thrown 30 to 35 meters by the average male soldier. It has a 4.0–5.5 second fuse that ignites explosives packed inside a round body. Steel fragments (not to be confused with shrapnel) are provided by the grenade body and produce an injury radius of 15 meters (~45 ft), with a fatality radius of 5 meters (~15 ft), though some fragments can disperse as far out as 250 meters.^[1]

Use[link]

First the user adopts the "throwing position," feet spread apart with the grenade held squarely in the user's abdomen area.

Second, the user removes the safety clip from the grenade.

Third, the user places his non-dominant index finger in the pin of the grenade while maintaining a firm grasp on the body of the grenade and safety spoon (also referred to as a spoon) with the dominant hand so when the user does pull the pin, the spoon doesn't automatically fly off and ignite the fuse. As an added safety measure, the pin of a live grenade is bent so it prevents an accidental removal. When the pin is pulled, the user must pull hard enough to straighten the pin as it comes out. The pin is small and made of a relatively soft metal, making it somewhat easy to remove. Left handed people hold the grenade upside down in their left hand.

Fourth, the user firmly pulls the grenade away from the pin, ensures that the spoon is still intact, and heaves the grenade at the intended target. He may also let go of the safety, before throwing, and "cook" the grenade for a few seconds in order to ensure the enemy does not have time to throw it back before detonation. However, "cooking" a grenade is not recommended in all but the most dire defensive situations, as variances in the length of the delay fuse could cause the grenade to explode too near to the user. If tactically appropriate, the user yells "frag out" to warn others of the outgoing grenade. (Yelling "grenade" is a warning of an incoming grenade thrown by the enemy.) When the grenade is thrown, tossed or dropped, the safety spoon (which is under spring tension but was held in place first by the pin, then by the palm of the user's hand) flies off. This action frees a spring-loaded firing pin which snaps over onto a percussion cap, lighting the time delay fuse which is followed a few seconds later by detonation. The user takes cover from the blast.

The M69 Grenade is used for American training, to simulate the M67 grenade. When detonated, it releases a small puff of white smoke. The explosive charge within the grenade case is replaceable.
