Republic Armed Forces Military Ranks

The Republic Armed Forces follows fairly closely the standards set by the Star League (both versions in its rank structure. This system is familiar both to Inner Sphere soldiers through their training, as well as to warriors of Clan origin through their society’s veneration of the original League.[1]


Commanding General[edit]

The commanding general is the supreme commander of the Republic’s military, whose authority is surpassed only by the Exarch. They are selected by the Exarch based on recommendations presented by the Council of Paladins, and there is no limit on the term of service.[1]

General / Admiral[edit]

Generals are in charge of the prefectural forces or administrative divisions within the RAF. These include Military Intelligence, the Special Forces Command, Requisitions and Replacement, or the Civilian Relations Bureau. The naval-equivalent rank of Admiral is the supreme commander of the Republic Navy.[1]

Lieutenant General / Vice Admiral[edit]

Lieutenant generals are placed in charge of sub-commands within the RAF’s administrative divisions or military forces on a planetary scale. The Vice Admiral rank is used for the commander of national level naval organizations such as the WarShip Command and the Border Fleet, as well as the heads of naval staff commands.[1]

Brigadier General / Rear Admiral[edit]

This rank is traditionally used for the commander of a prefecture’s Hastati Sentinels line unit or the CO of an independent brigade. The naval-equivalent rank of Rear Admiral is given to those who command either one of the Republic’s WarShips or a Prefecture flotilla within the Border Fleet.[1]

The rank of Commodore denotes the commander of a regular RAF line unit’s aerospace fighter support and transport assets.

Major / Captain[edit]

Majors command battalion-level units or field staff organizations, as well as backing regiment-level officers as XOs. Naval Captains command single JumpShips attached to an RAF line unit, individual vessels within a Border Fleet flotilla or part of the WarShip Command’s support squadrons.[1]

Captain / Commander[edit]

A Captain is the commanding officer of a company-level unit or executive officers for Majors. Commanders act as executive officers on individual vessels, DropShip commanders, and leaders of aerospace fighter wings.[1]


Lieutenants command lance or squadron-size units. In the Navy, Lieutenants fill positions as executive officers on DropShips or commanders of aerospace fighter squadrons.[1]

Master Sergeant[edit]

The senior NCO in a unit receives the rank of Master Sergeant.[1]
