Bottom line, is that I know a few NN...here's a collective of how they feel (and yes, they are all hot):
As a Navy Nurse...you'll be asked to serve with the US Navy, Marine Corps, Army, and Air Force. The expertise that you bring will be used, and then you'll be asked to work in a field that you've never considered before. IE, if you're a pediatric nurse, you will get ER experience. If you're an ER nurse, you'll get surgical experience....they move you around to what they need and if you have ever had a chance to do a little of anything, you'll be used where you need.
I've served alongside of nurses that worked in Guantanamo Bay, Cuba, keeping terrorists alive who have been hunger striking and I'm currently very close with a gal in Afghanistan taking care of our seriously injured troops...you'll never know what tomorrow will bring, but my God...that's what keeps us lovin' our daily lives...
In many ways, it's alot like being a pilot, which is what this website is about...but it's important what you do and it's amazing that there are those that are interested in serving like you are. DO it, don't go AF and you'll have a blast. If you don't love it, get out after a few years and you'll be better for saying that you've served along some of the most amazing sailors, soldiers, marines, and airmen in the world.
(Bonus if you're a hottie)
