Fact is, know one knows til it happens. Variables abound here in hypothesizing. Where is the wound, how far was shooter, shot with what, direct hit or ricochet? Hopefully, if you have been trained in some aspect of warfighting or LE, that training will kick in. It may or may not. Example: After getting out of the Corps and combat, being trained in CQB and feeling on top of my game, I was shot in a drive by at work. Main road was 75 feet from loading yard, was hit with a .25 at 6 a.m. in Nov, so very low light. Recognized gunshot(training), took cover(training),waited for threat to pass as I was not allowed to posses a weapon on company property. @ approx 1 minute into event, a co-worker (former Army medic) noticed a dark stain spread across my upper thigh as we were behind the truck. His training kicked in as mine went out the door. Looked down,saw the blood and started to collapse. He put pressure on the center of wound while someone called 911. Ambulance arrived and heard the words "femoral artery severed". Within 4 and a half mins of being shot, I was in the hospital being operated on. Later found out Dr. told my wife if not for the Medic and that the hospital was 2 mins from scene, I would have bled out. As much as it pains me to say, this Jarhead owes his life to an Army dog. Kidding aside, his training kicked in while mine did not. The gist of this you can't KNOW until it ACTUALLY happens. You would like to think you can handle the things you have been trained for, all you can do hope it kicks in.
