How can you find a list of the military ranking system?

A complete list of military ranks and their associated insignias is available from Military.com. The site provides an index of rankings for all five branches of the United States military, including the Army, the Navy, the Air Force, the Marine Corps and the Coast Guard.

Rankings listed on Military.com are divided between enlisted rankings and officer rankings. Enlisted officers are assigned levels E1 through E9 across the United States military, though their titles vary between the service branches. Titles for commissioned officers also vary significantly. For example, in the Army, the highest ranking is that of general. In the Navy, the equivalent position is admiral.
