Which phrase is used to maintain positive control of the SOF Gunship or Army Attack Aviation during an engagement?

The phrase "At My Command" is used to maintain positive control of the Special Operations Forces (SOF) Gunship or Army Attack Aviation during an engagement because it indicates that the person in a position of authority is giving specific instructions for when to engage or initiate fire. This command establishes clear communication and control within a potentially chaotic environment, allowing troops to synchronize their actions and avoid friendly fire incidents. It ensures that everyone involved understands that engagement will not take place until the commander explicitly states to do so. This is crucial in military operations where precision and timing can drastically affect mission success and the safety of personnel.

Other options may convey different commands, but they do not emphasize the same level of control and timing as "At My Command," making it the most appropriate choice for ensuring coordinated efforts among units.
