The Imperial 676th Light Support Scouts was a unit in the Imperial Army. It seemed to serve no function except to house murderers, thieves, cowards, and the less intelligent until their term of service ended.
The unit had the reputation of being "the first to arrive, and the first to die."
Lex "Mad Vornskr" Kempo was a member of this unit when he deserted the Imperial Army to join the Red Moons.
