what needs doing?

The United Nations Space Command was formed by the United Nations during the Interplanetary War. After the UNSC victory, overpopulation on Earth became a major issue in the early 22nd century. This issue was resolved and disaster averted by colonizing and constructing vast cities on other planets in the Orion Arm of the galaxy, the Inner Colonies and later the Outer Colonies. The UNSC's defensive military force is the UNSC Defense Force, and consists of the UNSC Air Force, the UNSC Army, the UNSC Marine Corps and the UNSC Navy.
