- ―Armat M20 Claymore Mine description (from Aliens: Colonial Marines)
The M20 Claymore Mine is placed on the ground and will detonate when a target crosses the moving red laser sight trigger. The M20 is best used to prevent flanks or to slow down an advancing force. The United States Colonial Marine Corps typically employs the M20 as a trap for their enemies. M20 Claymore Mines are very effective against Xenomorphs since the M20 is hard to notice and usually overlooked by them.
