Though the military does have some excellent benefits for education, you when considering whether to go active duty or reserves (which includes the Air National Guard), there is quite a bit to consider. While active duty service makes you eligible for tuition reimbursement of courses that you take, understand that you will be working 40+ hours a week, probably on a varied schedule. Once you are done with your service, though, the GI Bill (and the fact that you will be considered 'independent' for financial aid purposes (which otherwise requires you to be 26yrs old, married, an emancipated minor, etc) provides quite an advantage over a civilian.
Long story short, consider all parts of the Air Force: Active, Reserves, and Guard.
With all deference to AFRescueMedic, I disagree on the subject of hands-on patient care in the AF. With the current level of deployments, all company grade officer (Lieutenants and Captains) RNs, with VERY FEW exceptions, are now on notice that they will be practicing nursing in a forward area, which is very much hands-on.
I work in an ICU in San Antonio and can personally attest to the level of hands-on care that I perform daily. In over 5 years of AF nursing experience, I have been hands-on, working shifts, for all but about 3 months of the time. 2 Years med-surg, 1 year ER, and now going on 2 years ICU. Though most of our bases have downsized their clinics, the staff from the Super Clinics are sent here to attend trauma training and refresher in preparation for deployment.
We may have our share of 'clipboard nurses', but that won't be a concern for anyone until they have been in for several years...
