I'm currently serving Active Duty in the USAF and I returned from a regular 6 month deployment earlier this month. My last day of R&R was the 19th and I returned to regular duty on the 20th. I was told I would not be getting a day off for Memorial Day because I was on R&R earlier in the month. This does not sound right to me and was looking for some more input on this, preferably a regulation because I've searched around and can't find anything connecting holidays and R&R.

I just got back from the dealer and need a co-signor for a car. Personally I think it's dumb that dealerships won't just sell you the car without a co-signor if based off your income you have plenty of money to pay the monthly payments so why use a co-signor?

Edit: I'm active duty military, 20 yr old male, with a 672 credit score.
