Joint Chiefs of Staff (KDTA)

The Joint Chiefs of Staff, also simply known as the Joint Chiefs, were a command organization within the Galactic Empire, comprised of the individual heads of the separate branches of the Imperial Military. Members of the Joint Chiefs usually held the rank of Grand Admiral or Grand General, though Generals, Admirals, and Fleet Admirals also were allowed to serve on the Joint Chiefs.

Individuals who held the ranks of Colonel (for ground-based forces) or Rear Admiral or Vice Admiral (for naval forces) were also allowed to serve on the Joint Chiefs, but usually were holding their positions on an interim basis only.

Organization

 * Chairman of the Joint Chiefs of Staff: The overall leader of the Imperial Military, usually exclusively holding the rank of Grand Admiral or Grand General. Sometimes referred to as the Supreme Commander. The Chairman of the Joint Chiefs was also a member of the Imperial High Command, and was the only member of the Joint Chiefs to be a member.
 * Vice Chairman of the Joint Chiefs of Staff: The second-in-command to the Chairman, and therefore the second highest-ranking military officer in the Empire. Also usually holds the rank of Grand Admiral or Grand General, but can be a General, Admiral, or Fleet Admiral. In the absence of the chairman, the vice chairman presides over the meetings of the Joint Chiefs of Staff. He may also perform such duties as the chairman may prescribe.
 * Chief of Staff of the Imperial Army: The leader of the Imperial Army, sometimes referred to as simply the Chief of the Imperial Army. This rank was usually held by either a General or Grand General, but a Colonel could hold the rank in an acting capacity as well.
 * Chief of Staff of the Imperial Navy: The leader of the Imperial Navy, sometimes known as simply Chief of the Imperial Navy. This rank was usually held by a Grand Admiral, Fleet Admiral, or Admiral, but a Rear Admiral or Vice Admiral could hold the position in an acting capacity.
 * Commandant of the Stormtrooper Corps: The leader of the Stormtrooper Corps. Though nominally under the jurisdiction of the Imperial Army, due to the constant expansion of the Stormtrooper Corps, the Commandant of the Stormtrooper Corps eventually gained its own seat on the Joint Chiefs of Staff. The Commandant was usually a General or Grand General, though a Colonel could be Commandant in an acting capacity if required.
 * Chief of Special Operations: The head of the Imperial Special Forces, or SpecForce. The position was also known as Chief of SpecForce.
 * Chief of Military Intelligence: The head of the Imperial Military's intelligence division, which overall functioned as the Empire's primary intelligence organization.
 * Chief of Military Research:
 * Commandant of the Imperial Reserve Corps: The leader of the Imperial Reserve Corps, which functioned as the overall reserve/auxiliary force of the Imperial Military. Typically held by a General or Admiral, but a Colonel, Rear Admiral, or Vice Admiral could hold the position in an interim capacity.
