IW Devastator Marine

An Iron Havoc Support Squad Member wielding an Autocannon

The Iron Havoc support squads of the IVth Legion were an elite formation utilised by the Iron Warriors Space Marine Legion during the Great Crusade and Horus Heresy eras during the 30th and 31st Millennia. Amongst most of the Legiones Astartes, it was the principal role of Legion Heavy Support Squads to saturate an area or target enemy armour with heavy ordnance obliterating an enemy through sheer weight of fire. The Iron Havocs of the IVth Legion, however, were an elite formation who had elevated these tactics almost to an art. These warriors were amongst the finest marksman of the Iron Warriors, placing both shell and explosive blast with exacting precision as they advanced alongside the Legion's assault cadres. Iron Havocs were often attached to the leading elements of any assault, where their pinpoint accuracy allowed them to scour clean fortifications and strongpoints of enemy infantry with murderous efficiency, clearing a path for the Iron Warriors infantry to sweep aside any survivors.
