You're far more marketable outside of flying becuase:
1. You know how to lead and motivate people. To the unknowing, they think you bark and the boys jump. To those of us who know, depending on that method means they'll manage to screw it up unless you use the leadership tools you are taught and learn. It takes more skill than it seems to.
2. You can manage complex processes and commonly, budgets.
3. You understand how to work in a structured environment (i.e. follow operations procedures, understand OSHA).
4. Demonstrated ability to make rapid, accurate decisions in a pressured environment (i.e. with people shooting at you!)
5. Responsibility for your actions and an ability to see the big picture.
6. Work ethic, trainability, blah blah blah
Generalizations, of course.
You can end up in a scenario (like me) where you're short on the PIC time to get hired by a major due to being in a multiplace aircraft and never doing an IP tour.
In reality, a significant portion (50%+ from my experience) of aviators that leave the military go to non-flying jobs. Many of those never fly again - I was always amazed at the folks that never got their FAA equivilency done.
I got hired by several regionals, a cargo airline and probably would have been hired by a fractional, but instead I'm working as a management consultant. QOL, Benefits and $$ smoke check the flying world, I thouroughly enjoy the work (some may not) and I fly on the weekends for fun. And I find it is more fun when you're not being paid to do it!
But ---
It all depends on what motivates you to get out of bed in the morning!
