All these competition techiques are ok in my book for midrange engagement, but fiddling the sight to set it at 500m and shooting little 2x4 rectangle at a cadence of 1 rd/sec at 7 yards are wrong. This is not "close range shooting" - it is just simulating long range shots with a small target at close range, like the cadats shooting .22 conversion kits in the basement at 20yards to simulate shooting at 200 yards.
Well, if you look at these "close range" shooting for the same reason the Cadats shoot in the basment , there is nothing wrong. However, if the objective is to teach soldiers to put down human beings at close range, I found the design of the matches as well as the gaming techniques very troubling.
