How long does it take for package to arrive Iraq?

My husband is currently deployed to Iraq and it takes anywhere from 5-7 days for him to get a package. I usually send letters priority or in a priority box to him because if I dont it can take anywhere from 10-14 days to just get a letter. I have been lucky sometimes with shipping and some packages have gotten there in 3 days worth of time...but I think that was just luck with the connecting flight to bring the packages over and space available. They will only take what they have room for. If they have ammo or supplies to send over to the troops they most definitely will send that stuff first before any mail which can delay delivery of your package(s).
