Car Loan

I have an 06 rsx that i bought with a 625 credit score and pay like 500 a month w/ 9-11% interest i think. when i bought it i had 3,000 in credit card debt and had only had a credit history of 2 years. now that i am 21 and have 3 years of credit history, and have paid off all my debt down to 0, plus made payments on this car for 1 year, i was planning on refinancing the car this year. i am doing this mainly so i can afford the car when i am in the army this year, however i was wondering if the army can provide any discount (like a credit union) for re-financing if i sign an allotment or something so the creditor is sure they will get their money. someone have any info on this? @ kathy i know how a credit union works and i believe my credit is at something like 710, but i know the army has a lot of discount worked out with various institutions and i was wondering if being the army would help lend me credit for something like a refi. obviousely i would only be doing this once i have been in for at least 6 months.
