If you need to polish, Ill need a grinder, I got out of the army 28 years ago.
I got out in 2008, but I did a lot of NRA and Tactical courses up until 2010. The best one I did was in Quad-City, Illinois. It was a 300m distance, 80 foot tower climb, shoot 12 targets, decend, run 150m, 150 m prone 12 movers, 6 innocent 6 targets 4 meters apart. Another 75m shoot from wall edge, engage popups. 70m run, opening door 1 second shoot/no shoot pistol. And it was a 16 minute timed course. I did it in 7 mins 100% accuracy.
Edit, there was some gas mask shooting in there somewhere after the 75m wall.
