Why is feedback from tracer rounds important for a gunner?

Feedback from tracer rounds is vital for a gunner because it allows for real-time adjustments to maximize effectiveness. Tracer rounds emit a visible streak of light, enabling the gunner to observe the trajectory and impact of their fire. This immediate visual feedback reveals whether rounds are hitting the intended target or if adjustments in aim or elevation are necessary. Consequently, the gunner can make swift corrections to improve accuracy and effectiveness in engaging targets.

While the other options provide interesting insights into different aspects of military operations or shooter morale, they do not directly address the primary function of tracer rounds in giving instant feedback essential for refining shooting performance on the battlefield.
