The Modern Army Combatives Program was started by the service in 1995 at Fort Benning, Georgia, with a mission to train soldiers to fight hand-to-hand and to sharpen the warrior mind.
Rather than beat the enemy into a pulp, MACP is intended to teach a soldier to subdue the enemy enough to grab another weapon.
It's not like the Army is training MMA fighters here.
The average infantry trooper learns the basics of combatives, such as grappling and controlling a resisting opponent's body. Soldiers who compete in the tournaments held by the Army are those who take their Modern Army Combatives skills to the next level.
More advanced combatives skills draw from Muay Thai, Boxing, Greco-Roman Wrestling, Brazilian Jiu-Jitsu, and Sambo martial arts styles, among others. It becomes more complex when training with weapons as well.
The footage compilation below comes from the 2015 Modern Army Combatives Tournament held at Joint Base Lewis-McChord, Wash. The first round of competition was for basic combatives, the second round through the finals featured more advanced techniques.
The finals featured a "Tactical Enclosure" – also known as a cage – with open striking.
