What command is used to signify readiness before starting any exercise?

The command used to signify readiness before starting any exercise is "Attention, MOVE." This command is essential as it establishes a clear expectation that participants are to focus and prepare for the upcoming activity. The "Attention" command directs individuals to adopt a proper posture and mindset, ensuring that everyone is alert and ready to proceed with the exercise. Following this command with "MOVE" initiates the physical activity, providing a seamless transition from a state of readiness to action.

In contrast, the other commands do not convey the same level of readiness and focus required before starting an exercise. For example, "Standby, MOVE" suggests a less formal readiness state, while "Ready, MOVE" or "Prepare, MOVE" may not have the same commanding authority in military contexts. The correct terminology is crucial to maintain discipline and consistency in physical readiness training, making "Attention, MOVE" the appropriate choice.
