This is a great video if one wanteed to learn MMA/GBJJ,but it is not usable as a form of battlefield combatives.

No one wants to go to the ground especially if a Police officer or Military troop loaded up with gear,such as vest,pistol belts, with cuffs,pistol,mags,mace,radio,baton just as a minimum.

If one goes to the ground the objest is to get back up and continue,not stay on the ground and continue or hold until help arrives.

Just my two cents
