Flag officers, Generals and Admirals, depending on how many stars they have, may have two types of assistants. One is called an "Aide de Camp" or just "Aide". This is an officer who's duty is to manage the flag officer's schedule, and basically do what the flag officer needs him to do. The other type of assistant is called an "Executive Assistant" who assists the flag level officer in performing flag level duties. This is normally an O-6 level job (Cols and Navy Capts). Both are incredibly demanding jobs, and only top quality officers are selected for these duties.
