ONI Signal Corps
From Halopedia, the Halo wiki
The ONI Signal Corps is a sub-branch of the Office of Naval Intelligence, staffed by members of the UNSC Navy and Marine Corps.[1] One of the Corps' roles is to send ships to unpopulated sections of human-controlled space to broadcast a large collection of radio transmissions in an attempt to confuse the Covenant and stop them from finding colonies. One of their operations in the Human-Covenant War was the Radio Beacon Deployment Program.[2]
