Clad in Mk X Phobos-pattern armour, the light and fast-moving Primaris Infiltrators are responsible for disrupting enemy communications and sabotaging targets of opportunity. The first the enemy sees is a cascade of choking smog as the Infiltrators hurl a barrage of smoke grenades, masking their advance. As the foe peers into the swirling cloud, the Space Marines bring their targets down with disciplined bursts of fire, the augur-scopes of their marksman bolt carbines lighting each victim up for the kill. Each Infiltrator is armed with a marksman bolt carbine and wears Mark X Phobos armour festooned with pouches for their infiltration gear. Additional parts are included to build up to two Sergeants and up to two models with comms arrays.

This kit contains two identical frames, each containing five models which can be built as Infiltrators or Incursors. The set comprises a total of 266 components, 10 Citadel 32mm round bases and a Space Marines Infantry Transfer Sheet.
