The one on the right looks like a rock. On the left, not so much. I'm not sure what position that's called when they have their hands clasped in front of them. I don't recall it in the Drill and Ceremonies manual, but they are not together. Marine on the right has his feet at the rest position, shoulder width apart. The guy on the left has his feet at attention. Right hand Marine's cap is squared away better.

I suspect if their 1st Sgt is watching, he is steaming! 😏
