Clad in heavy Gravis armour, Aggressor Squads advance on the foe as walking fortresses of ceramite. More mobile than some other Space Marines, they’re better able to negotiate rough ground, making them versatile troops; while they are often employed in specific circumstances or on certain terrain, Aggressor Squads are used as reserves to plug breaches in gun lines or to spearhead an advance. The range of their weaponry is not too long, but when they get close enough to open fire, the result is a sweeping fusillade of large-calibre bolter shells that can shatter enemy charges.
