M67
Model: M67 GrenadeA modern fragmentation grenade used by the US armed forces since the late Vietnam War, as well as the Canadians as the C13 grenade. It is classified by some as "High Explosive Dual Purpose" grenade, as it combines mild concussive blast effects with a fragmentation effect.
The body is baseball shaped to ricochet off walls and roll easily in urban combat, made of steel to provide sufficient fragmentation from the Compositon B filler.
The kill radius of the grenade is roughly five meters in diameter, combatants in this range being more or less certainly dead. Within rooms, the concussion effect of the M67 is also amplified, though not as much as an actual concussion grenade.
Out to fifteen meters, shrapnel is dense enough to seriously wound and probably kill unarmored combatants. Additionally, the fuse housing can be launched at a velocity high enough to damage armor, and random pieces of the body can fly out to several hundred yards.
Where to find: The US and Canadian militaries use these grenades in large quantities, but fragmentation grenades are relatively rare on some bases. They come packed in cylindrical cans.
Complexity:
These grenades are designed to be simple to use, but their hand-tossed deployment and extreme power in close range makes their use the real difficulty.
Size and weight:
The 14 ounce, steel body M67 is about 2.5 inches in diameter and 3.5 inches tall.
Action:
A percussion-type fuse has a delay of three to five seconds once the spoon is released.
Controls:
A large safety spoon is affixed to the grenade body, and secured in place by both a safety pin and safety clip (also called a "jungle clip.") They are designed for right handed users.
Deployment: 1) Hold the grenade in the right hand, the spoon facing the thumb and the pin on the right side. If left handed, hold the grenade upside down.
2) Hold the grenade tightly at chest level, then use the left hand to remove the safety clip - squeeze it to unhook and discard.
3) Pull the pin away from the grenade in a pulling and twisting motion to overcome the crimp.
4) Toss the grenade immediately - the spoon will fly off automatically, arming the grenade
5) Take cover. Fragments can hit you as far as two hundred feet away.
Field Stripping:
Grenades are not cleaned. However, one should check the grenade when acquired or pulled out after long periods without use. A cracked body, rusty or brittle looking fuse and pin, a partially removed or partially, but not fully crimped pin. Many of these mean that the grenade simply should be disposed of as soon as possible.
Design Quirks:
Due to the unpredictable nature of an M67's fuse, cooking is a very risky procedure. "Cooking" means to release the safety lever before tossing the grenade, and is used to catch combatants with an aerial burst, or to prevent tossing back. Generally speaking, if cooking is ever done the grenade should be tossed after two seconds at absolute most.
