Defining the failure to follow an order given by an commissioned officer is simply a commissioned officer giving an order to a subordinate, and the subordinate not fulfilling the task for an unacceptable reason such as a mismanagement of time or the subordinate is just not doing what he or she was ordered to do as long as it is a lawful order. A Lawful Order is an order given to you by someone appointed over you by higher authority which you are legally bound to obey and that does not require you to break the law to obey.
A Direct Order can only be given by a commissioned officer, who has received their commission from the President of the United States. A direct order must also not be in conflict with established law which means it must not require you to break the law.
Any order which would require you to break the law is an unlawful order and you are duty bound not only to disobey the order, but to report it to competent authority as soon as possible.
Any person who violates or fails to obey any lawful order or regulation, having knowledge of any other lawful order issued by a member of the military, failing to obey the order which is his or her duty to obey, or is rundown in the performance of his duties shall be punished as a court-martial may direct. When given a order by a Non Commissioned Officer it is to be presumed it is a lawful order. If it is not that is the only time you may refuse to do that order but you must be tactful on how you say that you refuse to do that order. If you do not obey the order or regulation that is given to you by th Non Commissioned Officer it falls under disrespect and it is very disrespectful to not obey the Non Commissioned Officer. You don't have to respect the person just the rank. The Non Commissioned Officer has been in long enough to earn that rank and the responsibility that come with it. By not doing what the Non Commissioned Officer told you may be also holding a mission or you may be wasting the Non Commissioned Officers time to deal with other solider. There are many things that can happen if you don not obey an order or regulation given to you by a Non commissionedOfficer like for instance writing an RBI, giving a class, or possible a article 15, etc. Failure to obey lawful order falls under article 92.
Disrespect to a Non Commissioned Officer is a serious offense. It shows lack of military bearing and lack of self control....
