A commander in the Army is a commanding officer or team leader. Another way to look at the term is that the rank of commander in the Navy or Coast Guard is the equivalent of a lieutenant colonel in the Army. These field-grade Army officers command a battalion, a fighting or support force numbering between 300 and 1,000 men and women. Noted by the silver oak leaves on their shoulders, lieutenant colonels are two steps below general officer status.
