If you were told your career was over today what would you look at as a potential fall back career in the private sector

If you're a field oriented Soldier, look at a construction related career. The pay is pretty good and you're outside not always stuck in some office or cubicle. My first good paying job after serving as a Field Artillery Officer was working in a chicken plant as a supervisor. Never being satisfied with that and shift work I finally ended up in building material sales. I'd also look into Junior College or technical college teaching.

Honestly right now if my career was over.... I'd look two places. The first being the police force back home, and the second would be at the private security companies that are protecting the pot fields in Colorado and Washington.

International Development or International Relations would be the ideal sector to fall back on - potentially getting hired on at a small NGO to gain a baseline understanding of project/program management before trying to apply at one of the major international development or international relations organizations.
