The Iron Warriors are a Legion of ruthless engineers, called upon to break sieges, dismantle defences, and garrison the galaxy. The iron skull icon of the IV Legion strikes terror into their foes, for the sons of Perturabo advance like a grinding engine of steel and fire, without rest or remorse, guided only by the cold arithmetic of war as they lay down relentless barrages of heavy firepower.

This upgrade kit can be used to customise Legionaries from the MKVI Tactical Squad set with new heads, trading out the standard 'beaked' helmets for the grim iron masks favoured by the Iron Warriors. The kit includes nine helmeted heads in three different designs, each featuring a skull-like mouth grille or heavy central bar, as well as two heads designed for Sergeants – one bare head with a bionic eye, and one helmet with a distinctive transverse crest of wrought iron. Spread these components around your army to add some IV Legion flavour, or outfit entire squads for an elite, unified look.

This upgrade kit comprises 11 resin components and is designed to be assembled with the MKVI Tactical Squad set, which is sold separately. These components are supplied unpainted and require assembly – we recommend using Citadel paints.
