Legion Vigilator

The End of the Legiones Astartes.

Not to be confused with the Sisters of Silence Vigilator Cadre.

Legion Vigilators were a type of Space Marine used by the Legiones Astartes during the Great Crusade and Horus Heresy. They were noted to be quite badass and hardass to boot, even by the standards of the Legion.

Overview

A ruthless sniper armed with either a Stalker Bolter or Nemesis Bolter, Vigilators specialized in scouting and infiltration. Vigilators, however, differ from either conventional Scouts or Recon teams in that they are lone wolves; preferring to operate alone to target and take out high-value enemies. Although they are just as capable to lead a recon detachment, striking at their foes’ most vulnerable points with sabotage and assassination. Due to their operations, the Vigilator wore more modern armour of its time, such as the Mark IV: Maximus Armour or even the Mark VI: Corvus Armour due to its stealth aspects. Although some Vigilators may forego power armour altogether and stick with the easier-to-maintain Scout Armour. Replaced with Scouts and Eliminators.

Crunch

On the tabletop, Vigilators are awesome Captain-sized spy-scouts. They grant Scout to attached units, and Stealth too if they take Cameleoline. Take the time to downgrade their Power armor to Scout armor, and they also gain Infiltrate and Move through Cover, although Infiltrate won't be conferred on joined units.

They have Special Issue ammo and the Sniper special rule, so take advantage of Precision shot and snipe that apothecary with a precisely-placed Shred+Rend Scorpius round), and get a pre-game Sabotage attack of D6 S5 AP6 hits (that always targets the weakest facing on a vehicle) on a 2+. Make sure to wear your best troll-face when you get First Blood in the deployment phase. Vigilators are the natural choice to lead Seeker squads as they have the same ammunition. Only downgrade to Scout Armor if you plan to pair them with Recon Marines (in Recon Armor, god damn it GW), possibly with a Storm Eagle.
