The other levels do start to bring the troops to a level of combatives,again the techniques taught are not done with gear on,they do get to wear an equipment belt but it is left open so they can roll and work on the ground.
Most troops do not reach the upper levels of the course,(most in Iraq now have what is seen on the video only)
The Military is in the process of changing the material.
Many see MMA(sport) as street applicable for all,but when one has on a vest,that restricts breathing and movement,a pistol belt loaded with gear and a weapon to protect,ground fighting is a last option and an officer should not stay on the ground fighting,they need to get back to their feet as quickly as possibe.
Ground fighting for Officers and military should consist of exposure to being taken down and then how to get up,not pin,submit or hold an opponent on the ground.
