1. tracer bullet; star shell; flare bomb
2. Tracer ammunitionTracer ammunition (tracers) are bullets that are built with a small pyrotechnic charge in their base. Ignited by the burning powder, the pyrotechnic composition burns very brightly, making the projectile visible to the naked eye. This enables the shooter to follow the bullet trajectory in order to make aiming corrections. When used, tracers are usually loaded as every fifth round in machine gun belts, referred to as four-to-one tracer.
