I stumbled across this video by accident while meandering through the halls of YouTube and thought that everyone would benefit from it. This is a 20 minute video from Pat McNamara. He spent 22 years in Special Operations and now has his own training company alongside a few books, like Sentinel and T.A.P.S.
In this video, he is demonstrating the various malfunctions of the AR platform and how to clear them with members of the 10th Mountain Division.
Speaking of training, how is yours going?
