Hi CelticWarrior,
The US Army COMBATIVES program as designed by then SFC Larsen was set up in a multi phase level of instruction,that few ever get to see beyond the first phase.,(Instructor level mostly see the whole thing)
The First Phase is set up upon BJJ /Sambo as UFC styled sport.
This is taught to recruits as the largest base and then carries on as troops stay in the military.
SFC Larsen had said that BJJ was a contact sport ,used to instill aggression,create self confidence and build unit cohesion.
(he also said it was to be used to try and create an Army level competiton of large scale to allow for the possibility of finding some who could carry over into the UFC or UFC type events,as we see he accomplished that goal as well)
The downside is that all those arm chair people who watch the TV and saw UFC type events,the Gracies,BJJ and all that saw what was supposed to be seen that MMA/UFC,Gracie, styled combat was the best form of fighting,which is not true due to the constraints of the sport,the rules and lack of gear that military/police have and use.
What is seen in the Army UFC version IS their COMBATIVES program,for the most part,the most used ,the most wide spread part.
When a recruit is told that if used on the Battlefield,pin and hold the opponent until help arrives to HELP,then you know you are falling short of a REAL WORKING COMBATIVES program.
No one with gear on can fight that way.
No one in a Combat zone can have the time to pin and hold and wait for help,if needed for Combat it must have strikes and attacks to injure,cripple and kill from the outset with finishing moves,not sport.
For Police actions,or military police actions, maybe some potions can be used to subdue and pin or restrain,but again the gear limits functional use of these moves on the street.
I hope this answers your questions.
