Directional mine
A directional mine is a mine that sprays out its explosive charge in a wide, directional arc. Directional mines use a shaped charge which directs the explosive force in one direction. These mines are usually triggered by tripwires and are often used in ambush situations [Oxford Reference].
Directional fragmentation mines: these are designed to be positioned in the direction the enemy is likely to advance from. This mine can be victim-activated by a tripwire or command detonated. Once triggered, it projects metal fragments in a specific direction.
Omni-directional fragmentation mines: these are hidden above ground in vegetation and triggered by a tripwire. It spreads metal fragments in a 360-degree arc [Gichd].
