One of my best buds is an ex-Major/flight nurse. She loved working in the AF, she flew on C-9s for a tour and met her husband a pilot of the C-9.
She tells me that with the nursing shortage on the civie side, AF life is a little more stable. I am refering to work hours and duties. She loved nursing in the AF, but dual military couple got more difficult as they both got higher in rank. She finally bailed as an 0-4, her husband now wearing a star.
There is also a difference in the civie world, as a nurse in a hosptial you can stay a regular floor nurse for your entire career. In the military as you rise in rank, you will be expected to supervise other nurses and lead them. You maybe sent to jobs that you don't always like, but there are no strikes about hours, benefits or lay-offs to cut cost.
Basically she will like the work and when she is sick of it she can leave and write her ticket for where she wants to live and work. Where else can you live in Germany, work for 4 years and then move to Alaska.
