I served in the USAF for 20 years.
So did the guys the military decided were murderers, which is possible even in a combat zone..a long standing ROE. They too wore a uniform and served. Sometimes the difference gets blurred in the heat of battle, and I've never had to face a choice like that, but the people of experience who judged their cases saw murder.
But I make an example of the fact a uniform does not make it's wearer a sterling character.
However neither does it negate the earned respect a wearer deserves. The uniform is a symbol, like the flag, and deserves our respect. Obviously, in the case of Vindman, that respect has shifted to Shifty Donald in certain circles. What irony! A Prez gets caught in a bald-face unconstitutional bribe in front of a whole bunch of people and expects them to cover his butt, and a patriot calls him on it, thru proper channels, and the cult of 38% goes ballistic..not over the crime but over the exposure. Amazing!
