What is the difference between Attention and At Ease?

• A. Attention requires no talking and a strict posture; At Ease allows limited movement and talking in a controlled manner.
• B. Attention allows talking; At Ease prohibits talking.
• C. Attention is a casual posture; At Ease is rigid.
• D. At Ease requires no talking and a strict posture.

Answer: (A)

The difference being tested is how formal and quiet each stance is. Attention is the most formal and rigid position: you stand with a straight body, heels together, feet aligned, arms at your sides, head and eyes forward, and you remain completely still and silent. At Ease relaxes that level of discipline: you can shift your weight and adjust your stance a bit, and you’re allowed to speak in a controlled, softer tone when permitted.

So the best match says that Attention requires no talking and a strict posture, while At Ease allows limited movement and talking in a controlled manner. The other statements mix up who can talk or how strict the posture is, which contradicts how these drill stances are used.
