just a thought thought.....
it depends where the bullet hits, obviously if its in the head, then it will pretty much rip your head off (7.62), but if in the leg, it will knock you over and you will be screaming in pain(assuming it doesnt hit an artery). so lets assume we have a gunner(IN A TANK), he is a nervious person, and is scared of the noise the gun makes. he sees some one, pulls the trigger, and off the rounds go. he is weak, so he cant hold it very well so it sprays like mad. the likely hood of the round going through his head or heart is reduced a lot, so about 3 rounds would go into him killing....eventually, but anyway its C&C generals, like i previously said, so accuracy aint a problem. and this situation is unlikely
lol
have you ever fired a .22 rifle or .303? (small bore) there bullets are tiny, and if shot somewhere in the body(apart from heart,head or lungs) it wouldnt kill you.
heres why..
when you fire the gun, lets say it produces 3000j of energy(maybe more/less depends on gun). about 1000j(joules) would go into you, and the rest of it would carry oin straight through you. so thats 2000j wasted. if its was a 7.62 round, it would produce even more, say 5000j or 5kj. again about 1000/2000 would go into, and the rest would exit you body. however, as it is such a big round, it would make a big hole right through your body, maxamising damage, as it would have taken out several major arteries/veins. if it was a .22 round, it would leave a small wound, but enough for you to die of blood loss, depending if it hit an artery/vein. Hunting rounds are specifically designed to counter this. when they hit a target, the bullet mushrooms and splits, so it doesnt leave the target, but stays in its body. if the gun produced 3000j of energy, all of the energy(exclude that lost on the way to the target,depending on how far it is) would stay in the target, increasing damage, and the force would knock it back and kill it, depends on the target again, say a rabit and a fox. put it this way, it takes about 50 pound, (maybe less) per square inch to knock a full sized human being to the floor. a 7.62 round would produce ABOUT 1500(possibly more) pound per square inch........ enough to kill. that concludes are physics lesson for today:P
