Speaking of obfuscating, a service member who "disobeys an order simply because he or she does not politically of [sic] ideologically agree with the Commander-in-Chief" isn't at all the same thing as refusing an unlawful order -so maybe drop that gambit.
Further, is it a failure on the Congress members' part not to "add that 'no-no' to their 'simple reminder' of the law to active duty and reserve military members" when it's the obligation of both active and reserve personnel to, at the very least, be sufficiently knowledgeable of the Constitution, conversant with the UCMJ to uphold the Oath they knowingly took when they entered the military? Seriously, if it's taught in basic training that "military personnel have the right and obligation to disobey an unlawful order," is it not incumbent upon said personnel to know what constitutes an unlawful order?
