Tempestus Scions. They're the best the worst can get without going into super science or the supernatural. Gear that puts the average Guardsman(SEAF) to shame, Oriented toward lightning fast Deep Strikes behind enemy lines to achieve important strategic objectives, and so heavily indoctrinated that they'd kill their closest friend if a superior told them that they were a threat to the Imperium(Democracy).
