Which command is NOT part of the preparatory and execution commands for the maneuver under fire event?

The command "Prepare. Sprint!" is not part of the established preparatory and execution commands for the maneuver under fire event in combat fitness training. This event requires specific command structures to ensure clarity and uniformity in execution among the participants. The recognized commands set clear expectations for when soldiers should prepare and execute their movements during the drill.

The command "Set. Action!" indicates that the Marines should transition from a prepared stance to active engagement, which aligns with the intent of the maneuver under fire, emphasizing readiness and movement. Similarly, "Ready. Go!" creates a distinct cue for readiness followed by immediate action, ensuring a swift response. "Start. Move!" functions similarly by indicating the initiation of activity, prompting troops to transition into action.

In contrast, "Prepare. Sprint!" introduces non-standard terminology that does not fit within the typical framework of commands used in these drills. The absence of a clearly defined execution marker, as found in the other commands, detracts from the training's intent and may lead to confusion during high-pressure situations. Thus, this command does not effectively convey the necessary immediate transition from preparation to action that is crucial in maneuver under fire scenarios.
