Looks like it is time for some good ole' GMT....

Ok, here is how it goes. If the Navy provides you with housing, i.e. BEQ, Barracks, Ship's berthing, then they don't have to pay you to live out in town. If there are no barracks or BEQ available the Navy has to pay you to live out in town. At A school and power school BEQ is provided. At Prototype it is not. As previously stated, if you go surface you live on the ship in port and sub guys get BEQs. Now, if you are an E4 you can live out in town but it will be on YOUR dime unless you are over your 4 year point. You will not get BAH(money for an apartment). If you are an E5 you do get BAH if you live out in town.
As far as the stuff in your apartment, things like TV, Video games, and stuff like that you can put in your BEQ. Stuff like furniture is less likely to find its way into your BEQ. It is a matter of what you plan on doing. If you plan on reenlisting right away(not avisable, wait until you get a good idea of what you are going to be doing for those 6 years) then you will be give E5 and can start living out in town with BAH. Thus you will need furniture. If you already have some from Protoype, that leaves you more money to blow on fast cars and fast women. If you choose not to re-up, then you can store your furniture untill you either decide to sell it or you move out into town, whether it is payed for or not. You can rent furniture while you are at prototype if you choose too. Usually it isn't too much a month and you get completely furnished. Of course it is money down the drain, but at least you don't have to worry about what you are going to have to do with it later. Best advice, if you are going to spend money on furniture, don't buy cheap so you have to replace it 4 years later when you run off and get married. Buy something that is nice enough to keep for a long time. Get a good mattress.
Hope that helps some more. Now if you will make sure you name is on the Training attendence sheet I would greatly appreciate it. Oh and don't sign anyone else's name that wasn't here either.
