I served in the U.S.Navy, 1980-1986, as a crypto-linguist with a TSC, and am a traditional Conservative (Goldwater-type).
Firmly, I believe active duty military service ought to be one of the eligibility requirements to serve in the Congress and the Presidency (V.P., too!.) If not enshrined in the Constitution, then unwritten and customary.
Fortunately, the Founders were smarter than making military a prerequisite for elected office. It helps keep the overlap between civilian government and armed services to a minimum. Military careers didn’t do too much for a slew of liberals or democrats that I can name off the top of my head.
I’d also hate to think the multiple seizures I experienced in Basic Training and effectively ending my enlistment would prevent me from running for Congress at some future date. Just so I don’t keep you in suspense, I was later found to have a cerebral AVM. That’s not something that can be faked.
