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. Volkite culverins emit scorching heat rays that burn through swathes of infantry, while versatile autocannons spit shells that shred troops and light vehicles alike. Lascannons are the most powerful laser weapons available to Legionaries, firing devastating beams to punch clean through tank armour.
