The '''TR/9 Antipersonnel Mine''' ('''TR/9 AP Mine'''){{Ref/Site|Id=Bnet|URL=https://halo.bungie.net/stats/halo3/careerstats.aspx?player=Sniper%20X%20Remix|Site=Bungie.net|Page=Halo 3 Career Stats|D=23|M=07|Y=2019}}, commonly known to [[United Nations Space Command]] forces as the '''trip mine''', '''"Tripper"''', '''"Skippy"''', '''"Automatic Guard"''', "'''Invisible Fence"''' or simply '''"Mine"''',{{Ref/Book|Id=Enc09|Enc09|Page=342}} is a [[landmine]] developed by the the UNSC.{{Ref/Book|Id=EVG|EVG|Page=47}}

==Overview==
===Design details===
The TR/9 takes a circular form, with six fins protruding off the side. The centre of the disc has another four fins that, when the mine is activated, rotate upward. The mine's activation also sees it light up and emit a high-pitched beeping noise. The mine can use trip wires or [[laser]] beams to trigger the detonator, when something large enough gets within range.{{Ref/Reuse|Enc09}} Despite its flower-like appearance, the TR/9 trip mine is not the [[Lotus anti-tank mine]].

===Usage===
The tripmine is employed for defensive usage, and is used in siege warfare and guerrilla tactics. They are used in the defence of perimeters or placed alongside enemy paths.{{Ref/Reuse|Enc09}}

==Operational history==
The TR/9 trip mine was originally developed for UNSC forces, though as with many pieces of equipment, was often stolen and deployed by [[Covenant]] loyalist [[Jiralhanae]] forces during the later stages of the [[Human-Covenant War]].{{Ref/Reuse|EVG}} Jiralhanae equipped with these mines were deployed during the [[Battle for Earth]] and [[Battle of Installation 00]] in late [[2552]].{{Ref/Game|H3|Trip Mine in-game equipment}} In the [[Post-Covenant War conflicts|post-war]] era, [[Jiralhanae Jumper]]s allied with [[Merg Vol's Covenant]] also employed the TR/9 trip mines.{{Ref/Level|HSA|Mission 16: Escape from the Southern Fields}}

==Gameplay==
*Sometimes, while playing in [[multiplayer]] or [[campaign]], players can either accidentally run or drive over their own trip mines or those of their teammate(s).
*A trip mine's distinctive beeping and orange glow makes it easy to detect.
*The trip mine will only stay active for 90 seconds before spontaneously exploding.
*Trip mines can be detonated from a distance by weapons fire, and are therefore only useful when unnoticed.
*The trip mine is often difficult to use in [[split-screen]] local games due to the sound it makes when deployed, causing other players to [[screenwatch]].

==Production notes==
In earlier stages of [[Development of Halo 3|development]], the trip mine in ''Halo 3'' had a Covenant-themed texture, featuring purple metal and blue lights. This [[Cut Halo 3 weapons|cut variant]] can be found in the files of the ''[[Halo 3 Beta]]'', though unused.{{Ref/Twitter|Kashiiera|1485054590542307330|Kiera キ|Quote=Today I learned a covenant tripmine exists in the Halo 3 Beta|D=13|M=02|Y=2022}}{{Ref/Twitter|Kashiiera|1492585987490426880|Kiera キ|Quote=I could make it different, the H3 beta only had the model and textures leftover not the actual equipment :(|D=13|M=02|Y=2022}} In the ''Halo 3 Beta'', deployed trip mines could stick to the bottom of a motionless vehicle. If the vehicle then moved, the mine would explode, killing all players inside of it.

==Trivia==
{{Linkbox|gameplay=yes}}
*The trip mine's [[heads-up display]] icon, along with that of the [[Z-4190 bubble shield|bubble shield]], can be used in a ''Halo 3'' [[Emblem]].
*Trip mines can be used to [[Overload glitch (Halo 3)|overload]] a map or [[Flying Elephant|launch an Elephant]].
