"If a sensor detects an enemy infantry target in an M5's killing zone, it can launch the mine, which pops up to 2 m from the ground whilst spinning. As soon as the mine's directional charge faces the enemy it explodes, firing a cone-shaped spray of lethal fragments up to 50 meters."
- M5, as described in the Aliens Colonial Marines Technical Manual
The upper line of images shows what a detonation of the mine looks like in the mod. The first explosion appears when the propelling charge in the platform launches the mine into the air, followed closely by the explosion of the mine itself once the optimal height has been reached.
The Recon class comes with two of these.
