I am a nursing student as well and graduate in December. I am planning on going Army when I graduate. The reasons I chose Army is because the deployment is (supposed to be 3 months)..but you may have multiple deployments within a year and the Navy deployments are 1 year or longer from what I understand...you will also have the possibility of being stuck on a ship at sea for whatever time...My army buddy is also an RN stationed at walter reed..his housing allowance is $1600 a month but he shares a townhome with another officer and pockets the leftover money...from what he tells me he has every available amenity there is to use on base..the exchange, gym, etc. and as far as boot camp, he said its more classroom time than pt, but the pt is very easy stuff. sorry i cannot give you more info about the NAVY but I hope this helps somewhat..
