Operation: BRAVADO

Operation: BRAVADO was a classified operation of the Office of Naval Intelligence Section Three.

History
On May 20th, 2544, in her personal journal, Doctor Halsey makes note of the project, stating how aside from the fact that it has proven useful in fighting back the Covenant threat, that she knew nothing of the operation.

At 1:00pm on July 18th, 2552, the head of ONI Section Three, Hieronymus Michael Stanforth sent a response message to Margaret Orlenda Parangosky, the director of ONI, providing her with information on the events of the recent Battle of Sigma Octanus IV. In his message, he mentioned numerous UNSC vessels, such as the Leviathan, the Coenwulf, the Cradle, and the Iroquois. He also made note of numerous locations on Sigma Octanus IV, such as Caracas, Huiren, Côte d'Azur, Silma and Enfield, describing them as having become "parking lots" in the battle. After stating that the Covenant were transmitting some data from the planet before he had managed to destroy the beacon, he referenced Onyx, Meridian, Arcadia, and the Babd Catha Forerunner complex that Doctor Halsey was excavating on Reach. He claimed that 18 Covenant vessels were destroyed in the battle, and that it may take years for the planet to recover. Supposedly, this data is all relevant to BRAVADO.
