M67: A Closer Look at the American HE-Frag Hand Grenade

The M67 is a spherical, High-Explosive Fragmentation (HE-Frag) hand grenade designed for anti-personnel use—characterized by its smooth casing and powerful Comp-B fill. Unlike its Mk II "pineapple" predecessor, the M67 features a pre-scored inner wall to produce lethal fragmentation without the use of a coil.

Its evolution from the oval-shaped M33 to the modern spherical form was part of a broader modernization effort in U.S. ordnance. A pyrotechnic-delay (P-DLY) fuze system and safety pin mechanism make it simple to deploy—but dangerously unpredictable if misfired. EOD teams are trained to wait at least 30 minutes before approaching a dud, due to the risk of a hung striker.
