Tracers work both ways. If you take more than your fair share of objectives, you will get more than your fair share of objectives to take. When both sides are convinced they will lose, they're both right. The more a weapon costs, the farther you will have to send it away to be repaired. Military Intelligence is a contradiction.
Radar tends to fail at night and in bad weather, and especially during both.
Weather ain't neutral. The Cavalry doesn't always come to the rescue. Napalm is an area support weapon. Mines are equal opportunity weapons. B-52s are the ultimate close support weapon.
