Asmara

Asmara was a UNSC Colony in an unspecified system. Sometime relatively early in the Human-Covenant War a battle took place on Asmara, which involved Gage Yevgenny's team of Orbital Drop Shock Troopers. One ODST to die in the battle was Mason, after a Sangheili speared him along with ten other ODST's with an Energy Sword before Gage got off a near point-blank shot with a missile launcher.

The colony's fate is unknown, however in all probability it was destroyed by the Covenant.
