In which battle drill do troops react to indirect fire?

The correct choice pertains to the protocols established for responding to indirect fire, which is a critical aspect of troop safety and battlefield awareness. Battle Drill 9 specifically focuses on the actions soldiers should take when they are under indirect fire, which includes artillery, mortars, or rockets. This drill emphasizes immediate reactions such as seeking cover, maintaining communication, and ensuring accountability of personnel.

Understanding this drill is crucial because indirect fire can occur unexpectedly and represents a significant threat on the battlefield. Soldiers must be trained to respond quickly and effectively to minimize casualties and maintain operational integrity. The structure of this drill reinforces the importance of quick decision-making and situational awareness in high-stress environments, which is a fundamental skill for a Cavalry Scout.

In contrast, the other battle drills emphasize different scenarios, such as reacting to enemy contact or actions on contact, but do not specifically address the immediate responses required for indirect fire threats.
