Prone Standing Armlock
b) Key Points
Use this technique as a transitional one to keep you safe from his ability to attack you while you assess your environment.
His body weapons are facing downward, away from you, allowing you to safely kneel on his back while maintaining control over his arm with a bent wristlock/ straight arm bar/ posted shoulder combination.
PRO TIP: be sure to maintain the bent wristlock (with his fingers always pointing at his head) when transitioning to the prone handcuffing position, as he is held more in position from the bent wristlock and shoulder posting than from body weight being applied to his back.
The downward posting action of his straight arm shoulder into the ground (aided by the bent wristlock) will help keep him in the prone position (kneeling on his back will further help keep him in this position).
Proceed to the (kneeling-on-his-back) prone handcuffing position before applying the first handcuff.
