technically you don’t even need a war. They can say they need some specialty that a particular person had in the service or even a need for members at their rank or assignments or such. I mean take that with a grain of salt but its what I have been lead to believe with conversations with folk who had been in. You can apparently resign your commission and then you can so go take a leap but you lose all benefits at that point. And for some, maybe, honor bullshit or whathaveyou.
