I, (NAME), do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God.
Is it bearing true faith and allegiance to the Constitution to follow the orders of a person who may not meet the Constitutional requirements to be President? I think not.
I suspect he's unaware of the facts on Obummer's eligibility.
