Once the back mount has been achieved, keeping it is the most important goal. The position learned earlier of one hand in the armpit and the other over the opposite shoulder allows the most possible attacks.
a. Collar Choke.
(1) Step 1 (Figure 4-42). Grasp the collar with the hand in the armpit, pulling it open to insert the thumb of the other hand deep into the collar. Secure a firm grip.
Figure 4-42. Collar choke, step 1.
(2) Step 2 (Figure 4-43). Change the grip of the hand under the armpit to grasp the opposite lapel, pulling down to tighten the collar against the back of the enemy’s neck.
Figure 4-43. Collar choke, step 2.
(3) Step 3 (Figure 4-44). Set the choke by pushing outward with both hands.

b. Single Wing Choke.
(1) Step 1 (Figure 4-45). Open the collar and secure a grip the same as in the collar choke.
Figure 4-45. Single wing choke, step 1.
(2) Step 2 (Figure 4-46). With the hand that is under the enemy’s armpit, pull his arm out at the elbow.
Figure 4-46. Single wing choke, step 2.
(3) Step 3 (Figure 4-47). Bring your hand around behind his head and finish the choke by pushing out with both hands.

c. Straight Arm Bar.
(1) Step 1 (Figure 4-48). If the enemy is protecting his collar effectively, push your arm further through his armpit, pulling your own collar open with the other hand. Grasp your collar with the hand that is through his armpit.
Figure 4-48. Straight arm bar, step 1.
(2) Step 2 (Figure 4-49). With the palm of your other hand, push his head away and step your leg over it. Break his grip by pushing with your legs and extending your body.

(3) Step 3 (Figure 4-50). Finish with hip pressure against his elbow as in the basic straight arm bar.
