What is the first battle drill as defined in military training?

The first battle drill as defined in military training is "React to Contact." This drill is fundamental for soldiers, as it provides a structured response to engaging enemy forces effectively. The ability to react quickly and decisively when contact is made is critical for maintaining the initiative and ensuring the safety of the unit.

The drill typically includes specific actions such as taking cover, returning fire, and assessing the situation to formulate an appropriate response. The importance of this drill lies in its focus on immediate actions that can be performed under stress, allowing soldiers to react instinctively in combat scenarios.

Other options, such as conducting squad or platoon assaults, build upon the foundational skills developed in the React to Contact drill. They emphasize more complex operations that require prior experience with immediate responses in combat situations. Establishing security is also an essential task, but it often occurs after the initial contact has been made and does not represent the immediate reaction necessary in a contact situation.
