Tracer rounds are projectiles trails that can be seen after a weapon is fired.
In Combat Arms, about one out of every five bullets is a tracer bullet. They are most often used to trace a shot back to the person who fired it, hence the name.
The S2 Suppressor can reduce the amount of tracers you fire.
- Turning off "Flare" in the settings menu will eliminate tracers from your screen, which can actually prove to be a handicap.
