Listen up, politicians.

Whether you’re running for president of the United States, any seat in Congress, the statehouse or a seat at City Hall, take care when referencing any military experience.

There will be folks out here who are listening to your every word.

Roy McDowell is running for mayor of Amarillo. He’d been referring in public statements to his military service “in Vietnam.” Turns out McDowell didn’t serve in-country, but served during the Vietnam War era.

Why bring this up? Because some of us who actually did serve in Vietnam are keenly aware of these things and want to be sure that all vets — whose service is honorable — portray their service honestly.

Is this a deal-breaker? Probably not, but McDowell and other politicians need to be acutely aware that the world is watching and listening.

He’s not the first politician to fudge a little. U.S. Sen. Richard Blumenthal, D-Conn., did a doozy of a job mischaracterizing his own military service before being elected to the Senate. He, too, said he’d served in Vietnam when he hadn’t. Bad call, senator.

This also reminds me of a young man whose acquaintance I made some years ago. He told my wife and me he “flew helicopters” in Bosnia and Kosovo in the mid-1990s. When he said he “flew,” I assumed immediately he piloted them. We would talk about his experience “flying” Apache choppers for the Army. I assumed, of course, that he either was a warrant officer or was commissioned. He well might have flown aboard the choppers, but perhaps as a crew member.

Why make that leap? Well, years later, I happened to be browsing through his office and discovered his discharge certificate on a wall. It listed his rank as private, E-1. What? How could he have “flown” helicopters if he’s a mere enlisted man — and a buck private to boot?

Take great care, politicians. If you fudge on your service record, you can be caught.
