This could be a humorless fake. 

 Cool!

So what's the deal with the "arab guy" having a wedding band, or some kind of jewelry, on his left hand?

These funny cultural awareness classes the Army has been teaching us say you don't shake the arabs' left hand, 'coz that's the one they wipe their @ss with (and don't always wash their hand afterwards with soap and hot water).

 

Why would you wear jewelry on the hand you wipe your @ss with?

And the wearing of wedding bands at all (on the left hand), isn't that a predominantly christian/catholic/western belief?

Why would you adhere to western customs in that fashion if you're muslim?

(or at least, wouldn't that betray your religious convictions to surrounding muslims who might not take so kindly to your christian/catholic/western displays of beliefs?)

 

I'll give it that the "arab" guy's mustache isn't US military regulation (unless he's Navy, maybe?),

but his teeth seem rather healthy and his general appearance (principally his fairly clean, well-kept hands/nails) doesn't give the appearance of the livestock tender or hard-laboring illiterate Iraqi (Afghani?) stiff he's being portrayed to be.

 

Probably a US foreign ally working alongside us over there, agreed to assist in faking such a picture.
