When I was on active duty in the US Army as a lower-enlisted(E-1 to E-4), we(our basic training class/plt & advanced course) were taught to "shoot to wound" or cause the enemy in combat to tie up 3 soldiers on the "battlefield"( the wounded enemy + 2 "battle buddies").
That seems strange to me. I don't doubt that you are telling the truth, but I have always been taught to shoot to center of mass in the Marine Corps. Even if you are off a bit, you still stand a pretty good chance at hitting something. While it is true that the primary goal is to incapacitate the target so that they are incapable of returning fire, one of the quickest and most effective ways to do that is to kill them.
