MACO Major Rank Insignia
Major is a military rank, the equivalent of which is used by the service organizations of many civilizations. As a traditional grade, Major is a line officer of a fighting organization, below a Colonel and above a Captain. In comparison to naval ranking systems, this rank is equivalent to the naval lieutenant commander rank. Some rank systems include an additional rank, Lieutenant Colonel, that is superior to Major and inferior to Colonel.
This grade exists in some form in many other culture's rank arrangements, such as the Romulan Tal Shiar and the Bajoran Militia.
Some rank systems use the term major in conjunction with other ranks to create a different grade, Major General or Sergeant Major for example.
The insignia for a MACO Major is a gold oak leaf. The oak leaf insignia appears to be carried over from the USA system insignia for Major.
Majors typically serve as the primary Staff Officer for brigades and task force command regarding personnel, logistical and operational missions.
