On the battlefield itself, no one will move if you are not moving. I used to tell my company commanders “If I, the battalion commander, will not go to a fire position, open fire and then give commands, no one will move. And if you company commanders will not be the first one to climb to fire position, every other tank crew will find some excuse not to climb, and we have to do it the first time.” You don’t have time. You somehow — I believe that many good commanders in the field just somehow can make their overall judgment very quickly. I can compare it to something in which I’m very weak but I watch it. The way that tennis players are responding. They’re not calculating. If you were to write the Newtonian equations of the moving of the tennis ball, what you should have done, or not to mention the Schrödinger equations of it, you will never end it. You’ve got to do what should be done and you don’t assess whether you should do it this way or this way, just do what should be done.
