Which of the following is NOT a rest position given at halt?

The correct answer is "Ready position" because it does not qualify as a rest position given at halt. When troops are commanded to rest at a halt, they are typically allowed to take a less formal posture, which is represented by the commands "Parade rest," "Stand at ease," and "At ease."

In "Parade rest," soldiers maintain a position that is military in nature, but allows for some relaxation. "Stand at ease" requires soldiers to keep their feet shoulder-width apart, with hands placed behind their back, while still maintaining a degree of military posture. "At ease" allows for even more relaxed posture while still retaining a sense of alertness and readiness.

On the other hand, the "Ready position" is a stance associated with being prepared for immediate action, which includes keeping a straight posture and alertness rather than a relaxed state. Therefore, it does not fit into the category of rest positions provided at a halt. Understanding these distinctions is crucial for comprehending military drill and ceremonies.
