A 'tracer bullet' is a type of ammunition that leaves a visible trail when fired, allowing the shooter to see the bullet's path 💥. It contains a pyrotechnic compound that burns brightly during flight. Unlike regular bullets, tracers are designed to be seen, not just to inflict damage. Think of them as fiery darts that illuminate the trajectory of gunfire. They help soldiers adjust their aim in low-light conditions and can also be used for signaling.
