'''Identification of Friend or Foe'''<ref>'''[[Halo: Contact Harvest]]''', ''page 178''</ref> is a system used by the [[UNSC]] to tag friendly or hostile units for easy identification on a [[Heads Up Display]] or [[Motion Sensor]].<ref>'''[[wikipedia:Identification friend or foe|IFF at Wikipedia]]'''</ref> 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.

In the ''[[Halo 2]]'' level, ''[[Gravemind (level)|Gravemind]]'', [[John-117]] managed to rescue a dozen UNSC Prisoners of War. This was due to [[Cortana]] identifying their "IFF Transponders", which were still with the Marines.

Most UNSC ships, ranging from civilian [[Freighter]]s to [[UNSC Navy]] [[warships]], possess IFF transponders displaying their identity, allegiance, and classification.<ref>'''Halo: Contact Harvest''', ''page 176''</ref>
