Design
The bottom of the landmine is crimped to the upper landmine body.
An adjustable cloth carrying handle is attached to the side of the landmine body, a large filler plug is positioned between the handle connection points and a booster well is centered on the bottom.
The landmine has a small diameter fuze cavity and a stamped radial pattern centered on the top.
Fuze
The landmine is almost always fitted with an M607 tilt rod fuze which can be detected visually, the landmine is also detectable using metal detectors.
Other fuzes available include the M612 pneumatic fuze and the M609 magnetic influence fuze.
When the tilt rod or pneumatic fuzes are used the M21 can be defeated by blast overpressure clearance devices.
