Rear crucifix

Rear crucifix is the alternate name for the back crucifix — the cross-shaped control configuration in which the attacker isolates both of the opponent’s arms simultaneously, one with each pair of attacker limbs, from a rear or back-adjacent angle.

Etymology. “Rear” specifies the angle (back-adjacent rather than front); “crucifix” specifies the cross-shape geometry of the trapped-arm configuration. The compound predominates in instructional contexts that emphasise the back-attack lineage.

Mechanics. Both of the opponent’s arms isolated simultaneously — the legs trapping one and the arms trapping the other — collapse the defensive options that depend on arm participation.

Cross-reference. “Crucifix (from turtle)” is the entry-context name. Full mechanical coverage on Back Crucifix.
