Such a high volume of radiation bleeds outward from a Skitarii Vanguard's wargear that even to stand nearby is to become weakened and fatigued; for non-Skitarii to be stationed in the same barracks is a death sentence. The Vanguard themselves are theoretically safe inside their war plate, but on the rare occasions these warriors unscrew their helmets, the sight of their missing teeth and hairless, sore-pocked skin tells the awful truth.
