Heavy Support Squads provide the Legiones Astartes with mobile, infantry-portable firepower sufficient to bring down hordes of enemy troops or smash armoured vehicles apart with withering hails of fire, combining devastating armaments with all the flexibility of a footsoldier. Heavy bolters are the largest bolt weapons available to infantry, unleashing a storm of shells that tear apart enemy formations, while missile launchers are prized for their versatility, offering a variety of explosive munitions suited to eliminating infantry, tanks, or aircraft.
