The Terran Hegemony was humanity's original interstellar empire, comprising of the planets surrounding Terra. For centuries the heads of House Cameron would be the first among equals in dealings with the various Great Houses.
By 2570 when the first Star League ascended to full maturity after the Reunification War, the Hegemony's military was largely a second-line militia. The most elite formations of the HAF had been folded into the SLDF as Royal Divisions. The units available to the Hegemony during the Star League represent what is typically found in defensive garrisons. This also includes fearsome technology incapable of leaving system such as the SDS drone networks and giant installations like the Rattler.
