Security Fleet

From Halopedia, the Halo wiki

The Security Fleet was a Forerunner naval unit or category of naval units.[1]

When the Flood began actively attacking the Forerunner ecumene's core systems late to the Forerunner-Flood war, the Security, Suppression and Emergency Circumstance fleets were all ordered by Forerunner Fleet Command to defend the core systems from infection by the Flood; however, they could not stop the parasite from overrunning the ecumene.
