Knowing how Uncle S. hates to let a certain class of folks go 180 days, I'm not too sure what will go on, but I'd really be surprised if they don't come home then. If they DO stay in Iraq, then I suppose PFC Edskid Jr. will go outside the tent, loudly curse the scenery in a general way to no one in particular, and then get ready for another day. In his case, he can't go back to college until the class rotation is right, so that might be one advantage he has over someone with a job and family.
He's only been in the unit for two years, but he already knows that the Army can be like the weather in Iowa: wait a while and it will get worse... or better.
....but their orders say up to a year...
