In marching commands, what does "Stand at ease" allow soldiers to do?

The command "Stand at ease" allows soldiers to relax their stance while still maintaining their position in formation. This means that they can shift their weight, adjust their posture, and breathe more comfortably, but they must remain in place and attentive to their surroundings. This command serves to give the troops a moment of relief from the rigors of strict attention while ensuring that they do not lose their military bearing or discipline.

By contrast, options such as moving freely in formation or stepping out of formation suggest a level of mobility and freedom that is not permitted under this command. Engaging in casual conversation is also not allowed, as soldiers must remain alert and ready for further instructions. The essence of "Stand at ease" is to strike a balance between maintaining military decorum and allowing a moment for physical relaxation.
