Summary
Override subroutines transmitted by Tech-Priests that remotely augment and direct Skitarii cohorts in battle.
Lore
Doctrina Imperatives are coded directives by which the Tech-Priesthood remotely controls the cohorts of the Skitarii. They are not orders given to a soldier but override subroutines loaded into the cybernetic substrate of the warrior — protocols the Skitarii cannot question, refuse, or interpret.
When an Imperative is broadcast across the cohort, the bodies and minds of every Skitarii within it are reshaped to its purpose: targeting cogitators sharpen, servo-musculature is overdriven, defensive subroutines lock joints into immovable braces. The cohort moves as one will because there is, in that moment, only one will — that of the Adeptus Mechanicus master who issued the directive.
Doctrine
Two great families of Imperative are spoken of in the current rites of war:
- Protector Imperative — defensive cant. Ranged weapons gain the Heavy aspect, ballistic-cogitation is sharpened, and battleline cohorts shrug off close-quarters violence. The cohort holds, and burns the foe from a fixed line.
- Conqueror Imperative — assault cant. Ranged weapons gain the Assault aspect, melee subroutines awaken, and battleline cohorts strike with deeper armour penetration. The cohort advances, and crushes.
Only one Imperative may be active across the army in a given battle round; the Magos in command shifts the cant as the tide of battle demands. Earlier doctrine (the cant of seventh-edition rites) recognised six gradations — Protector and Conqueror each in Gamma, Beta, and Alpha levels — where each ascending tier traded greater capability against the opposite spectrum, the cohort becoming briefly but fearsomely specialised.
Application
Imperatives are transmitted via the same noospheric and binaric channels that carry the Machine Spirit‘s lesser litanies. Stratagems of the Rad-Cohort lock onto the active Imperative: Aggressor compounds Conqueror with charge-after-advance; Bulwark compounds Protector with an invulnerable shield against incoming fire. Thus the cant of war is not a single command but a layered dialect — Imperative, stratagem, and litany sung together across the cohort.
