Looks photoshopped... the guard on the right is an exact replica of the guard on the left. Perhaps, they are identical twins.
I read somewhere a while back...they are.
Nah, the one on the left has more ribbons. Not identical.
No, the looks like the guy on the right is a MSgt and the one on the left is Sr MSgt, I think.
Regarding Michelle's attire, you can dress casually but still look put together. That's her problem - she looks sloppy. Maybe she needs to shop somewhere like Talbots vs. J Crew.
