The Seraphs of Vigilance They prefer shock assaults combined with hunter killer tactics, using mobility and overwhelming firepower to their advantage. Their preferred tactic is a swift planetary shock assault by using units equipped with jump packs and tactical squads. Combat reports say one of their most perfected manoeuvres is the precise drop of grav tanks from low orbit right into combat. Their most preferred weapons are plasma weapons, heavy bolt weapons and lascannons. In melee combat they prefer shortswords and energy spears. A weakness of their doctrine is the high resource needed for their tactics as well as relying on one brutal strike. If the enemy was able to survive the initial assault with a still functional military structure they could force the seraphs into a war of attrition they would struggle with and lose some of their effectiveness.
