An officer of the Armed Forces is not “loyal to Trump”. He is loyal to the Constitutional requirement that the President of the United States is the Commander and Chief of the Armed Forces of the United States.
Loyalty to a man is how the third world military leaders view their responsibility.
Thanks for the lesson in semantics, but I took that oath and understand what it means.
Resisters, insubordinates and others in the officer cadre seeking to thwart the will of or work against POTUS (like this a-hole, Vindman, Mattis etc.) can and should be dealt in the harshest possible terms - and there's nothing "third world" about it. People get sent to Djibouti all the time.
I can't be the first person telling you life in the military can gets difficult when you piss off or work against your commanders.
