Always has been that way, just ask the USMC and Army if their training was not a give factor in Iraq and Afghanistan. And that is also why they now spend so much time on marksmanship. They did a 180 degree turn from the Vietnam 'spray-n-pray' to precise marksmanship (and the optics help to!)
Yes, skill is not everything but again, but all other things being equal, it does help.
