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 ODSTs with an Energy Sword before Gage got off a near point-blank shot with a missile launcher.

The colony was one of the first eight to be destroyed by the Covenant, being destroyed sometime in the first four years of the Human-Covenant War.

Trivia
The colony is likely named for the city of Asmara, the capital of Eritrea.
