Helm of Censure
From Warhammer 40k - Lexicanum
The Helm of Censure is a red Ultramarines power armour helmet that contains within it the complete didactic works of Sergeant Aeonid Thiel. They detail the results of his pre-Horus Heresy studies, outlining the optimal methods by which an Adeptus Astartes could kill a fellow Battle Brother; which had originally led Thiel to be censured by his Legion for treason. Ten thousand years later though, the Sergeant's works are still without equal.[1][2]
