Which of the following is a method of control from ATP 3-09.30?

Each of the listed options represents a method of control as outlined in ATP 3-09.30, which is the Army's reference for fire support operations and procedures.

“Fire When Ready” is a method that allows troops to engage targets at their discretion, providing flexibility when conditions are favorable for the engagement. This method ensures that soldiers can act promptly without needing to wait for further instructions, enhancing responsiveness in dynamic combat scenarios.

“At My Command” requires troops to wait for a specific command before firing, which allows the fire support team leader to manage the timing and sequence of fires. This method is particularly useful in coordinated attacks or when timing is critical to mission success.

“Cannot Observe” is a control method used when the observer is unable to see the target or effects. In this case, the observer designates a reference and communicates the intended engagement to ensure clarity and effectiveness in the strike.

Since each of these methods is valid and included in the framework of controls for directing fires, it confirms that all options—Fire When Ready, At My Command, and Cannot Observe—are recognized methods from ATP 3-09.30, making the comprehensive answer accurate.
