Tracers work both ways. The only thing more accurate than incoming enemy fire is incoming friendly fire. Make it tough for the enemy to get in any you can't get out. If you take more than your fair share of objectives, you will have more than your fair share of objectives to take. When both sides are convinced that they are about to lose, they are both right.
Professional soldiers are predictable, but the world is full of amateurs.
