Assault Marines are jump infantry, meaning they can jetpack over impassable terrain. They are melee units, most effective when jumping on enemy ranged specialists. Because of their mobility they can quickly reinforce a weak spot in a fight or prevent an enemy squad from escaping. Assault Marines can be equipped with short-range melta bombs so they can jump in, bomb a vehicle or building, and jump out. You can also jump them into an enemy base to spot good targets for artillery or a place for some Deep Striking.
