Article 428-A

Article 428-A is a UNSC protocol in effect in 2552. The protocol forbids soldiers from discussing matters related to classified missions to any personnel who do not have the clearance. This includes anyone, even an AI, who questions the soldier before they are debriefed. Violation of this protocol requires the person questioned to report the offense to their superior officer and are possibly court marshaled.

The AI Lysithea posted at HIGHCOM Facility Bravo-6 is designed to test soldiers' adherence to this protocol, among other things, by questioning them about missions when they talk to her.
