In which position do the first rank start the Military Movement Drill 1?

The first rank starts the Military Movement Drill 1 in the starting position. This position is crucial as it allows soldiers to be poised and ready to execute the movements of the drill effectively. Beginning from the starting position ensures that all soldiers have a standardized stance, which promotes uniformity and discipline during the drill. It helps establish the correct posture and readiness before any movements are initiated.

The other options do not accurately represent the appropriate beginning stance for this drill. For example, standing at ease implies a more relaxed state, which is not suitable for the commencement of a structured physical activity. Family formation does not pertain to the individual positioning necessary for the drill's commencement. Starting in a kneeling position would not suit the drill, as it requires mobility and readiness to execute movements efficiently from a standing posture.
