In regards to your moving questions. As a 1st LT, you will be allotted 12,500lbs w/out Dependants and 13,500lbs with Dependants. Which means the Air Force will pay up to that number of poundage to be moved. If your total house goods way more than that then you would need to ship them abroad on your own dime or store it at a friends house for 3 years ;) As a family of 4 we didn't even come close to 13,000lbs!! Because you are moving abroad you cannot do a DITY move, the AF has to move you.
I have heard several people say they leave a lot of their electronics and kitchen items that plug in, behind in storage when they move overseas because they use a different plug system, wattage or something to that effect over there. Like if you try to plug in your hair dryer it will explode unless you buy special adapters for every single item you plug in. U.S. stuff isn't compatible over there. I wish I had more knowledge on this but I don't. I do know my friend when she headed over there was able to buy a toaster, hair dryer, blender, etc for dirt cheap b/c everyone that goes there needs it and then at the base thrift store people leave it there when they're ready to come back to the States.
I would suggest that as soon as you get orders to have your stuff shipped overseas. It will take roughly 3 months for your goods to be shipped overseas. The AF can load your stuff up from a storage unit, but you will have to be present and they will unbox EVERYTHING and then re pack it. Silly I know, but they are reliable for the items so that is their protocol.
