An Intercessor Squad is the mainstay of the Primaris Space Marine units, analogues to Tactical Squads.
Primaris Space Marines are the next step in the evolution of the Emperor's Space Marines. Primaris Marines are larger and more physically powerful than their standard cousins, in addition to having a more stable gene-seed. These mighty warriors have appeared in the closing days of the 41st Millennium following the Thirteenth Black Crusade and resurrection of Roboute Guilliman.
