 Getting over obstacles, pulling fellow squad members, and climbing to the top of ropes were all part of an event for Marines to earn the right to become Marine Corps Martial Arts program or McMap instructors. McMap is a class where Marines learn a variety of fighting techniques from bayonet techniques to ground fighting. They'll be able to mentor Marines and instruct Marines on Marine Corps Martial Arts program. The students tackled the obstacle course, sparred with pugil sticks and then got in some ground fighting. Today was the last day for the participants and also the hardest challenge of completing the three week course. Once we become instructors you're going to have young guys who can push, who can run and you have to be able to outperform them or at least be at a level to where you don't show weakness. Wevington also says this course was the hardest thing he has ever done physically and added that it's just as much of a mental challenge as it is a physical one.
