Newaza Drill. Side Control to Mount to Head & Arm Choke. 

This newaza drill uses a transition from side control to full mount and finishes with a head and arm choke. This is definitely intended for "consensual violence" and not for "non-consensual violence"/self defense. In a self defense scenario, the goal should be to escape, not to purposefully engage on the ground. There is a risk of a third party intervening when your head is down.
