The Interplanetary Strategic Alliance (ISA) is a member of the Alliance of Nations, meant to protect ISA occupied colonies and enforce them will by any means. The ISA acts as the main policing and defensive body for the citizens, and the main revenue gathering party for the local government. Each ISA command is directly subordinate to local colonial governmental authority, which in turn is subordinate to the Allied interplanetary authority. Since each ISA Command is an independent unit of each colony, it is not linked to the military command of the Allies. As a result, the ISA Command's budget and strength are determined by the funds each local colonial administration provides.
