MMA stars "Train the Troops" at military bases in recent visits across the U.S.

To my right, UFC fighter Tim Credeur and top Brazilian jiu-jitsu black belt and trainer Tim "Panda" Burill are demonstrating a particularly vicious guillotine choke/neck crank hybrid.  

"This is grimy, bro," Credeur tells the students gathered around him. "Like if you were in my gym and did this, you'd be taking a day off grimy, but for you guys this is a perfect way to end the fight."

As I look around, Tim Kennedy, Gray Maynard, Damacio Page, and Jorge Rivera are all working on similarly ill-intentioned techniques with groupf of deploying U.S. soldiers. It's a session of "Train the Troops," and organizer Lex McMahon hopes to bring the program to a military installation near you.
