Question about Iraq and the employment picture

I'd appreciate input from people on a question of mine.

How many men and women in Iraq are Reserves and Nat'l Guard?

I'm wondering, because that probably means most of them left a job back in the US that someone else is filling. When they all come home, they get their old jobs back (I think that's the law).
So, that means that the people who have been filling those positions will be unemployed. And those unemployed numbers will go back up. If they aren't assured of their old jobs then they will be unemployed and the numbers will go back up.

So...either way...the "low unemployment numbers" trumpeted by capt. oxycotin, shill o'lielly. et al are artificial in the sense that they are dependent upon the soldiers staying in the Middle East.

Is my analysis correct or am I way off?
