If the subject is lying on the ground after being grounded by the officer and is resisting, which control sequence is described?

• A. Arm bar from guard
• B. Headlock escape
• C. Knee control to back control
• D. Chin lock

Answer: (C)

When a subject is lying on the ground and resisting, the goal is to secure the hips and torso quickly to prevent turning or creating space, then transition to a stable, controlled position. Knee control to back control does exactly that: you establish a knee-in-place to pin and control the hips, which limits the subject’s ability to bridge, roll, or scramble. From there, you can bring your arms around to secure back control, keeping the subject restrained with a stable, protective posture that reduces the risk of escalation for both parties. This progression is preferred because it directly impedes the subject’s mobility and sets up a safe, controllable position for handcuffing or further restraint.

Arm bar from guard relies on a bottom guard position and aims for a joint lock, which isn’t the described scenario of restraining a resisting subject on the ground. A headlock escape is about freeing yourself from a headlock, not applying control. A chin lock is a choke, which is unsafe and not suitable for standard restraint or compliance.
