After being in the receiving end of uncle sams mailing system It doesnt matter how fast you ship it to an apo or fpo the mail once it leaves there it can take months to arrive in its final destination. I would not waste the extra money on the priority mailings as they do you no good. I do know that the APO mail center is In Miami Florida and the FPO mail center is out of San Francisco California. YThe mail going overseas is always shipped on flights over seas as space is available. weapons and medical supplies are priority. Next comes food. after that is items that are required for maintenance ect. then comes the Mail. I hope this doesnt cause anyone dispare. but it is how they work it.
