United Nations Space Command Emergency Priority Order 098831A-1

The Cole Protocol, otherwise known as United Nations Space Command Emergency Priority Order 098831A-1 is a command enacted by Vice Admiral Preston Cole to prevent the Covenant from finding the location of Earth. Essentially, it is an order preventing Covenant retrival of data that contains the location of Earth, and forbids retreating vessels from setting Slipspace course to Earth, as the Covenant are able to track Slipspace travel and find Earth's location. The policy also states that to prevent capture, any UNSC or Human vessel is to self destruct, after wiping all data matrices, to prevent the advance of the Covenant.
All UNSC personnel were commanded to read the Cole Protocol under NAVCOM UNSC Emergency Priority Order 098831A-1.

The Protocol

Article 1
United Nations Space Command Emergency Priority Order 098831A-1 Encryption Code: Red Public Key: file/ rst light/ From: UNSC/NAVCOM Fleet H.T. Ward To: ALL UNSC PERSONNEL Subject: General Order 098831A-1 ("The Cole Protocol ) Classification: RESTRICTED (BGX Directive) The Cole Protocol To safeguard the Inner Colonies and Earth, all UNSC vessels or stations must not be captured with intact navigation databases that may lead Covenant forces to human civilian population centers. If any Covenant forces are detected:

1. Activate selective purge of databases on all ship-based and planetary data networks.
2. Initiate triple-screen check to ensure all data has been erased and all backups neutralized.
3. Execute viral data scavengers (Download from UNSCTTP://EPWW:COLEPROTOCOL/Virtualscav/fbr.091)
4. If retreating from Covenant forces, all ships must enter Slipstream space with randomized vectors NOT directed toward Earth, the Inner Colonies, or any other human population center.
5. In case of imminent capture by Covenant forces, all UNSC vessels MUST self-destruct.

Violation of this directive will be considered TREASON and pursuant to UNSC Military law articles JAG 845-P and JAG 7556-L, such violations are punishable by life imprisonment or execution.
*It should be noted that Lieutenant Wagner broke Article 1 but was later pardoned.

Article 2
This article is never directly stated, though Captain Keyes uses it while his ship is crashing on Installation 04. Captain Keyes says "I'm initiating the Cole Protocol, Article 2. We're abandoning the Autumn. That means you, too, Cortana." Later saying, "Destruction or capture of a shipboard AI is absolutely unacceptable."
This implies that Article 2 directs personnel, or at least those with sensitive information, to avoid capture. Whilst it is not apparent to what lengths UNSC personnel are to go to ensure this, apparently in the case of AI's the worst case scenario only allows them to be hidden rather than terminated. Strangely, in First Strike there does not seem to be any attempt to recover any potentially surviving AI's.

Subsection 7
No [captured] Covenant craft may be taken to human controlled space without an exhaustive search for tracking systems that could lead the Covenant to Human bases.
Few had even heard of subsection seven because it was little more than a technicality, before the Ascendant Justice was captured. Because the humans could not completely search the ship, they instead planned to take it to Reach and try to return with a more prepared team.
*Note the number 7 in the subsection title.
