Glorious Advance

The Glorious Advance is a Phantom dropship used by the Covenant.

Background
In 2552, it was attached to the Flagship of the Fleet of Particular Justice, the Seeker of Truth. When the Infinite Succor was attacked, a team of Special Operations Elites and Special Operations Grunts, led by Rtas 'Vadumee, was dispatched to secure it and traveled from the Flagship to it onboard the Glorious Advance. It was later radioed by 'Vadumee and picked him up just before the Infinite Succor was destroyed.

Trivia

 * This is one of the two known cases where the Covenant have named individual dropships, although they are all probably named, just unknown to players and the UNSC.
