Kidou Senshi Gundam: Tekketsu no Orphans

Definition

Over three hundred years have passed since the Calamity War, the great conflict between Earth and its outer space colonies. Now Earth is ruled over by four economic blocs, and the military organization Gjallarhorn is responsible for keeping the peace. Mars, on the other hand, depends heavily on Earth's economy.
