Primaris Infiltrators are fast-moving specialists clad in Mk X Phobos armor, tasked with disrupting enemy communications and sabotaging key targets. Using smoke grenades to conceal their advance, they eliminate foes with precise fire from their marksman bolt carbines. Each model carries infiltration gear, with options to assemble up to two Sergeants and two with comms arrays. The kit includes 10 models, which can be built as Infiltrators or Incursors, featuring 266 components, 10 bases, and a transfer sheet for customization.
