[b]Conflict:[/b] Insurrection

[b]Date:[/b] 2545-2548

[b]Outcome:[/b] Mission Objective Accomplished. Results are Ongoing. [i](See: [b]Operation: WOODPECKER[/b] for further details)[/i]

[u][b]Overview[/b][/u]

[b]Operation: HUMMINGBIRD[/b] was one of many Sub-Operations authorized by the Office of Naval Intelligence Section-III, under the umbrella of [b]Operation: TREBUCHET[/b], that were performed outside of the Epsilon Eridani and Eridanus systems. These so-called 'Black Operations', which took place during 2525-2550, were never meant to exist on record outside of Section-III's databases. Reasons being because the focus was supposed to be seen as fighting the Covenant and [b]Operation: TREBUCHET[/b] had been 'officially' deactivated. As such, much of the data of these other 'Black Operations' has now been expunged. This report has not been altered, however, due to the continued events caused by this Operation. [i](See: [b]Operation: WOODPECKER[/b] for further details)[/i]

The objective of [b]Operation: HUMMINGBIRD[/b] was to infiltrate the Insurrectionist faction known as the United Rebel Front on the planet Victoria, by way of a double agent, to remain informed on the current movements of Insurrectionist Forces amongst all UNSC controlled systems. The target of this Operation was Insurrectionist Jonathan Anders; A known high-level Commander and well-respected Militant of Camp New Hope. After the capture and compromisation of the target, they were kept accountable and cooperative via blackmailing methods. 

A specially drafted team was selected to perform this Operation. The 37th Tactical Deep Ground Surveillance Unit; An ODST Task Force, separate from UNSC Marine Corps control and answering directly to Section-III, was composed especially for the aforementioned 'Black Operations'. Five members of this Unit were chosen to complete the Mission Objective. The sixth and final member, Specialist Jason Anders [i](Now promoted to Corporal)[/i], who was, at the time serving in the 53rd Armoured Division on Actium, was ordered to be redeployed within the UNSC Marine Corps and immediately assigned to the 37th Tactical Unit. Specialist Anders' inclusion for this Operation was seen as a failsafe in the event of non-compliance from the target. [i]Gunnery Sergeant Matthew D. Brown, who lead the team, was ordered that, in the event of non-compliance, he and the remainder of the team were to torture and threaten the life of Specialist Anders, after revealing his identity, to assure the target's cooperation.*[/i]
