Okay, I know this thread was started a couple of years back, but I see that there are still ome people responding to it...
I am certified in Modern Army Combatives, Level 3.
I am an still on Active Duty in the US Army.
I have spent time both in the Infantry and the Special Forces.
Having established that let me say this:
Modern Army Combatives is about confidence. Agreed, Level 1 is very basic and does have its limitations and problems. Level 2 comes full circle and ends the BJJ / grappling training. Level 3 brings into play boxing, stick fighting and kick boxing. Finally there is a Level 4 which is more admin in nature and focus on how to be a trainer and how to organize training and competitions at the higher levels (brigade and up in the Army).
Modern Army Combatives is not necessarrily meant to terach Soldiers an "alternative" to lethal force. It is meant to give Soldiers the confidence that in an unarmed fight they will have methods and techniques that they can use to, "close the distance, gain dominant body position and finish the fight." Yes, we practice most of the techniques with no boots on and no gear on... no system is perfect. Modern Army Combatives gives us Army guys a system to train from within the Army, and a system of competition within the Army. Also ther are many Soldiers that use this training as a springboard into MMA fights in their local area.
Give me any system and I'll show you how it is ineffective (my kung-fu is better than yours argument). For the Army, we were looking for a system that would foster the warrior spirit, give decent baseline skills (to everyone... Infantryman, Truck Drivers, and Admin Specialists alike). The fine Soldiers of the 75th Ranger Regiment looked to a BJJ centric system that works quite well.
Oh, and BTW... knives and bayonets? I'd rather be a bad ass grappler than a bad ass knife/bayonet fighter. NO one fights with knives and bayontes, and if I do get a weapon malfunction in the heat of battle I am more likely to have nearly a dozen others around me armed to the teeth to pick up the fight before I have to put my hands on someone. In 3 combat deployments since 9/11 I have known Soldiers who have killed enemy with firearms, and one friend who used some Judo throw that broke a guys neck, but no knife fights.
