What is the main purpose of a tracer round?

The primary purpose of a tracer round is to aid in tracking projectile flight. Tracer rounds are specially designed munitions that contain a small pyrotechnic charge in their base, which ignites when fired, creating a visible trail in the air. This visual cue allows gunners to see the trajectory of their rounds in real-time, making it easier to adjust their aim for future shots. By observing the path of the tracer, operators can quickly identify whether they are hitting the target or missing, thus improving their accuracy during engagements.

While marking targets for air strikes is a significant function in some contexts, it is not the main role of tracer rounds. Similarly, tracer rounds do not explode on impact like conventional explosive rounds, nor are they designed to simulate weapon noise. Their unique feature lies in the visibility they provide, which is critical for effective targeting and adjustments in combat situations.
