No problem. I'll work it out myself.
Of course, games give more practice than anyone gets in real life.
But it is just game playing. Wargamers tend to propagate what I call the myth of the "Kung Fu Master".
Meaning that the warrier can be skilled enough with his rifle, tank, plane, or sub to keep himself alive. I say it is a myth, since combat is a highly statistical experience. For most who are exposed, the numbers game will catch up with you.
So, why the myth?
(1) What fun would gaming be if the player was not in control, but the universal dice roller was?
(2) In real life, we do need to convince ourselves that dangerous activities are under our control. If not, we would be suffer PSDT before even seeing the worst.
So, we players drive our tanks, planes, and subs with great expertise. However, for ultimate realism you would more or less would die in the game no matter what you do given adequate playing time. For example, the best evasive techniques could be used, but someone with no idea of what they were doing would push a DC over the side just blowing holes in the water and that would be you. That's realism, but makes for rotten game play.
