The Infantry Assault Marine employs rockets, the Anti-Personnel Obstacle Breaching System (APOBS), and demolitions. Assault Marines provide rocket fire against fortified positions in support of the rifle squads, platoons, and companies within the infantry battalion. Additionally, Assault Marines employ APOBS, demolitions, and breaching/infiltration techniques to facilitate infantry maneuver in the offense, and demolitions and expedient counter mobility measures in the defense.
