I'm very sad about the fact that you don't see your target once you hit them in sniper mode.
But, the NPC's are so stupid when you snipe at them and miss, I've only missed a few targets at over 200 yrds. but when i did the guy whent prone, PRONE.
Who goes PRONE when your being shot at from in front with no cover. If your going prone do it under cover as a sniper nothing else
