What does it mean to hold a position of "rest" in military formations?

Holding a position of "rest" in military formations refers specifically to "standing at ease." When soldiers are commanded to stand at ease, it signifies that they are not in a state of immediate readiness for movement or action, but they must maintain a posture that is disciplined and proper. This position allows for a degree of relaxation while still being prepared to respond to commands if necessary.

In this position, soldiers shift their weight off one foot and may place their hands at their sides or behind their backs. While they are not completely relaxed, they do not have to maintain the rigid stance associated with more alert positions. This balance is important in military settings, as it helps maintain discipline and order, even in moments when active engagement is not necessary.

The other options, while they may have some elements related to military conduct, do not accurately capture the specific definition of "rest" in this context. The concept of a state of readiness implies preparedness for immediate action, taking a break suggests a more casual pause from activity, and a command to move directs soldiers into action, which contradicts the relaxed nature of standing at ease.
