In 2552, it was attached to the flagship of the Fleet of Particular Justice, the Seeker of Truth. When the Infinite Succor was attacked by an unknown enemy, a team of Special Operations Sangheili and Unggoy, led by Rtas 'Vadumee, was dispatched to secure it. The Glorious Advance transported 'Vadumee and his troops to the Infinite Succor. It was later radioed by 'Vadumee and picked him up just before the Infinite Succor was destroyed.
