Re: Risk to the shooter
A couple of points: the muzzle flash may not be noticeable at that distance, the sniper is likely firing very slowly - may be a minute between shots, and standard assault rifle only has an effective range of about 300 meters. Depending on how noisy the area was another rifle might not have been noticed. Also, snipers are trained to find tactical positions that make return fire difficult. The part most do not realize is sniper rifles are optimizing for 1000m + ranges while the standard issue infantry assault rifle is effective out to about 300m. Actually one of the best cures for a sniper is an artillery barrage, as a howitzer has a longer range and much bigger bang.
