PlanD, I was aiming for his foot, not his leg... I was qualified as an Expert Marksman with the M-16, .45, 9mm, and M-203....
I can tell u from my personal combat experience that the muzzle flash from an enemies weapon makes a great aiming point... Muzzle brakes and flash suppressors only work so good.. Most of my combat happened at night, or in the morning darkness...
Basic SEAL manouvering in combat is based on a simple concept: Throw as much lead into a given target area in the shortest period of time while withdrawing and call in air support or artillery... This massive onslaught of firepower is meant to overwhelm the enemy and make them think that the engaging force is larger than 10 men.... But then again, 3 M-60's on full auto, an M-79 autoloader, and 6 M-16's on full auto make for a rather convincing argument...
Point is, when ur are in combat, be it Iraq, Somolia or Omaha Beach, you were shooting to kill whatever ur errant bullets might hit....
