When should the command "squad halt" be given during marching?

The command "squad halt" is given when either foot strikes the ground, which is crucial during marching because it allows for a smooth and coordinated stop. This timing ensures that all members of the squad can effectively respond to the command at the same moment, which is essential for maintaining order and discipline during movement.

By executing the command at this point, it allows soldiers to complete their forward motion and come to a halt in a uniform and synchronized manner, which exemplifies the characteristics of military precision. Each individual's reaction to the command is critical, and aligning the halt with the moment either foot hits the ground ensures that the full squad can stop cohesively.

Other choices, while they may seem logical at first glance, do not reflect the practical application and timing necessary for this command in marching settings.
