it's one thing i always wondered. isn't it better to load before training? at college ROTC, we were prevented from touching any part of the '105 while the gunner and assistant gunner were setting trajectory. the reason was even a slight movement will throw the aim off. but i'm pretty sure loading a live round after this would create a bigger deviation, no matter how infinitessimal. also, it gives a moving target more lead in leaving one's aiming area. this, even during line-of-sight shooting, like in the case of an '88 anti-tank gun. so why?
