Ray, 18+ years ago I retired from the Army as a euphonium player/musician. Believe me, that doesn't translate well into civilian life. There isn't an overwhelming market for euph players and the few that there are have things more or less locked down.

Six months before I retired, I graduated with a BA in Management -- essentially a worthless degree.
But, at the time, it was enough to get me into pharmaceutical quality assurance -- specifically handling complaints. And I got into other things as well, but I'll save the long story for another time.
In my view ANY science degree is of value. Whether chem E, mech E, or whatever, it's all good in the job market. As BD notes, you'll do well when you're finished.
Good luck, and THANK YOU for your dedicated service!
