Commander is a naval rank which is also sometimes used as a military title depending on the individual customs of a given military service. Commander is also used as a rank or title in some organizations outside of the armed forces, particularly in terrestrial and/or interplanetary police and law enforcement.
In terms of authority in relation to other ranks, a General is the equivalent to an Air Marshall in the Air Force or an Admiral in navies and space patrol units.
