One of the best “do it live” hours of white space training I ever delivered- we had something fall through last minute, my platoon was gonna be without an hour of training on a parade night. So I went to CQ, pulled two C9s, put them both on a table in the classroom. One I left assembled, the other I detail stripped. Spent the lesson going into absolute granule detail on every tiny step of what’s happening with the gun during the firing cycle, what can go wrong and cause different stoppages, and what mechanically was happening with the gun. It bridged the troops from knowing the step by step drills to understanding what’s actually going on inside all the parts of the gun, round, and link, and why different things happen and why different things work to remedy.
I had nothing prepped for it, it was pure experience-based. We need that level of understanding for all the kit in use.
