IFF tags identifying UNSC soldiers.

Identification friend or foe, or IFF, is a system used by the UNSC and Covenant to tag friendly or hostile units for easy identification on a heads-up display or motion tracker.[1][2] The equipment of a friendly unit generates a signal on a specific frequency, which is interpreted as a "friendly" signal by the receiver. If a signal is not generated, then unit is tagged as a hostile. Friendly units appear as yellow dots on the motion tracker, while the crosshairs of a HUD turn green when pointed at them. Hostile units show up as red on a motion tracker, and the HUD crosshairs turn red.

All UNSC personnel are implanted with a neural interface containing an IFF transponder.[3] Additionally, most UNSC ships, ranging from civilian freighters to UNSC Navy warships, possess IFF transponders displaying their identity, allegiance, and classification.[4]

During the fall of High Charity, John-117 managed to rescue several UNSC Marine prisoners of war. This was due to Cortana identifying their IFF transponders, which were still with the Marines.[5]
