Crucifix Armbar
Crucifix armbar — the trapped arm extended by the attacker's legs while their hands stay free on the other arm. No step-over, no rotation, and the position survives the attempt.

The crucifix armbar extends the arm the attacker’s legs are already holding. In the crucifix the defender’s two arms are controlled independently — one trapped between the attacker’s legs, the other held by their hands — and the armbar is applied to the trapped one by flaring the knee to bring the ankle across the forearm and bridging the hips into the elbow.
Nothing about it resembles the rest of the family in shape. There is no step over the head, no rotation to perpendicular, and no hip escape. The attacker lies alongside the defender and never changes their orientation at all; the submission is applied by a limb that was already occupied doing something else.
That has a consequence worth stating early, because it is close to unique. This is the armbar that does not spend the position. The attacker’s hands never leave the far arm, their legs never leave the trapped one, and an attempt that fails leaves the crucifix exactly as it was. Most of the family trades a pin for a joint; this one asks the defender a question and keeps everything either way.
Elevated RiskCrucifix Armbar is an elevated risk technique. Elbow hyperextension driven by the attacker's legs. Legs are strong and poorly calibrated — they apply far more force than hands for the same perceived effort and they stop more slowly, which is the central hazard here. The defender's position compounds it: both arms are controlled, so the tap has to come from a foot or a voice, and they are usually facing away from the attacker. The load also arrives through a bridge rather than a squeeze, so it can climb faster than either player expects. Serious injury can occur fast, and poorly signalled — leg-driven extension with both of the defender's arms occupied.
