The Council of Admirals was formed by the Alliance of Independent Systems. The Council is a union of ships made up of a percentage of the fleets of Systems contained within the Alliance. The main purpose of the Council is to respond swiftly, with force, to threats outside of the Alliance without official government authorization beforehand.
"The Council of Admirals is a six-person body comprising the leaders of the six largest military forces in the Alliance. In addition to selecting the prime minister, the Council also commands the Alliance Defence Force, a vast flotilla of ships contributed by each of the Alliance's member systems. The Council of Admirals is free to deploy the Defence Force without the approval of the Assembly, making it extremely powerful."
