ECOAS (Earth COlony ASteroid) is a special task force established by the Earth Federation Forces in U.C. 0096. It was formed not long after the second Neo Zeon war. It was created as a clandestine group meant to do "wetwork", a.k.a. black-ops-type missions that are off the records. Because of its secretive and independent nature, ECOAS has its own command system that even Londo Bell has no authority over them directly. The task force first saw combat in Mobile Suit Gundam Unicorn.
