So he's back in Baghdad and it's 105 degrees. Quite a change from the snow he experienced when he was here. The chopper which was to ferry him back to the FOB was cancelled, as were all chopper sorties. Instead he's to phone his squad (why am I thinking of ET?) and they will send someone to get him.
They will be moving to another FOB, so he asks you to hold off on packages in case he gets a new mail address. It probably wouldn't be any different other than the zip code, but he'd rather not have to have packages "catch up" to him - he's not sure they do that very well
