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

The M67 Grenade has a steel sphere body that contains 6.5 ounces of Composition B material. The M213 fuse is specifically designed for use with the M67 fragmentation grenade. The M67 grenade is 14 ounces in total and has a safety clip for ease of manipulation.

Description

Two Marines take cover during M67 grenade training during a ROK/U.S. Combined Forces Exercise Foal Eagle in 2004.

The M67 can be thrown about 30 meters by the average soldier. It has a 3.0-5.0 second fuse that ignites explosives packed inside a round body. Steel splinters (not to be confused with Shrapnel) are provided by the grenade casing and produce a casualty radius of 15 meters, with a fatality radius of 5 meters, though some fragments can disperse as far out as 250 meters.[1] Its effectiveness is not just its blast radius, which measures approximately 45 feet (13.7 m) because splinters fly much further.

Use

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 lever (also referred to as a spoon by military members) with the dominant hand so when the user does pull the pin, the lever doesn't automatically fly off and ignite the fuse. At this point if the pin is accidentally pulled, the pin can be reinserted as long as the user maintains a grasp on the safety lever. 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 easy to remove.

Fourth, the user firmly pulls the grenade away from the pin, ensures that the lever is still intact, and heaves the grenade at the intended target. 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 lever (which is under spring tension but held in place by the pin) 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.

Inspection of Unpacked Grenades

1. Inspect unpacked grenades daily to ensure that the safety pins are present.

2. Check the body for rust or dirt.

3. Make sure the lever is not broken or bent. [2]

Alternative Uses

The M67 grenade has been a popular addition to movies, television shows, and video games. Contrary to how it is portrayed in Hollywood, it is nearly impossible to pull out a pin with your teeth.
