First, please allow me to say thanks for your service to our country.  
In response to your question, I would suggest going to a local community college and making a visit to their career counseling department.  I'm getting the feeling that you want to do something different but aren't quite sure what.  Please correct me if I am wrong.  I'm in a similar boat as you (although my career is not in the military).  I am 47 as well and I have spent over 24 years as an electronics test engineer at my company and I just needed a change.  Mid life crisis, boredom, you fill in the blank.  

  I went to the local community college and took a very long interest and aptitudes survey.  Turns out that I need a high tech kind of field with more people interaction.  I chose nursing as the one to best fit the bill.  I'm graduating one month from today with my degree.  Based on my clinical rotations and how much I have enjoyed it, it was the right thing to do.  Hope this helps.
