You have the option of assembling 3 Aggressors or 2 Aggressors and a Sergeant; a host of options are available either way. There are 6 heads for the standard Aggressors, with respirators on the mask of those using flamestorm gauntlets, and 2 more specific heads for the Sergeant. The flamestorm-wielding Aggressors have their own shoulder pads, featuring larger blast shielding to protect them from the immense operating temperatures of their weapons. Also included are reliquaries and purity seals, with special examples for Sergeants featuring extra skulls.
The Primaris Aggressors come as 107 components, and are supplied with 3 Citadel 40mm Round bases.
