-'''''Identification of Friend or Foe'''''<ref>''[[Halo: Contact Harvest]]'', pg. 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 tracker<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 reciever. If a signal is not generated, then unit is tagged as a hostile. Friendly units appear as yellow dots on the moption 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.<ref>'''Halo: Mortal Dictata''', ''page 292''</ref> Weapons like the [[MLRS-2 Hydra]] use an integrated IFF interrogator in its targeting systems to prevent friendly units from being targeted by the guidance system.{{Ref/Game|HI|In-game Hydra weapon|Detail=[[:File:HINF HydraIFF.png|Decal details]]}} Additionally, 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>

+Following the [[Human-Covenant War|fall]] of the Covenant, the [[Swords of Sanghelios]] and [[Jul 'Mdama]]'s [[Jul 'Mdama's Covenant faction|Covenant]] utilized "semi-feral" associated intelligences to operate {{Pattern|Upisa'weri|Shrike}} turrets. As these constructs had been long abandoned, they could not communicate with modern [[Sangheili]] and had to be carefully monitored and locked down prior to activation due to their inability to understand contemporary IFF systems and codeword usage.<ref>[https://www.halowaypoint.com/en-us/universe/weapons/shrike-turret '''Halo Waypoint''': ''Shrike Turret'']</ref>
