“When you take off your uniform, you can behave like any other civilian, and they do.”

And your oath comes off with the uniform?

[centurion316]

You take the oath when you receive your commission, you are literally, a commissioned officer of the United States. When you retire, you no longer hold any commission, you have certain retirement benefits and, by courtesy, your title. You are no longer bound by the oath. No different than a President or a Senator. Not part of the government any more.
