 Personally, I think the hardest part that they have to understand with McMap is the teamwork mentality. A lot of individuals lose that sight when they come out of her crew training in an FTP and comm school, but I like to train them as a team, one team, one fight. It's important for Marines to know and understand McMap as a baseline of a type of martial art style. Me growing up in a small town never had a fight in my life in my day and then coming to the Marine Corps potentially have to dig deep and ultimately save a Marine's life that day. It puts you outside of your comfort zone. It's challenging, you have to have mental fortitude to do it and if you don't have mental fortitude, I highly recommend doing McMap because it's going to help build up. Because you may not be able to get the techniques every time, but having that mental agility and fortitude is going to allow you to practice better and finally get those moves.
