Area denial artillery munition

Area denial artillery munition (ADAM) is a family of United States land mines and 155 mm artillery projectiles.

The mines carried by these projectiles are the M67 long-duration anti-personnel mines and M72 short-duration anti-personnel landmines intended to maim or kill enemy combatants.

Even if it fails to self-destruct, the battery will fully discharge after 14 days, rendering the mine inactive.

The mines contain a spherical warhead in a cavity, along with 51 grams (1.8 oz) of M10 liquid propellant.

The cavity allows the propellant fluid to settle under gravity in the correct position beneath the warhead, making it launch upward irrespective of the mine's orientation.
