The '''TR/9 Antipersonnel Mine''', commonly known as the '''trip mine''', is a [[Mine|landmine]] used by the [[United Nations Space Command]].
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 UNSC.{{Ref/Book|Id=EVG|EVG|Page=47}}


==Overview==
==Overview==
The Trip Mine is deployed as an anti-infantry or anti-vehicle weapon. It is sensitive to either proximity, pressure or both, and can be detonated by [[weapon]]s fire or the close proximity or impact of a [[vehicle]] or infantryman. It is apparently capable of detecting the anti-gravity generators found on [[Covenant]] vehicles.<ref>'''Halo 3''', campaign level ''Crow's Nest'' (''"Used by Brutes"'')</ref> The mine will explode after ninety seconds if not detonated before then.  It will not detonate, however, if a player crouch-walks over it. The technology it uses to detect nearby objects may be similar in nature to that of the [[Motion tracker]], which also fails to detect stationary vehicles and slow, crouched players.
===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]].


Once deployed, it can be identified by a high-pitched beeping noise, four inner spokes that rise up, and a distinctive flashing bright orange light on its top. Its blast radius is considerably larger than a [[grenade]] or rocket explosion, throwing vehicles and personnel into the air. Despite this blast radius, however, Trip Mines can only slightly injure [[SPARTAN-II Program|Spartan]]s and [[Elite]]s positioned near the edge of the blast radius, and it takes two direct hits with a Trip Mine to kill a Spartan or Elite. It will, however, kill [[Jiralhanae|Brutes]], [[Unggoy|Grunts]], [[Kig-yar|Jackals]], and unwary [[UNSC Marine Corps|Marines]], even if they are on the edge of the blast. The greater damage to Brutes may be due to the fact that their armor has no shielding and is weaker than the [[MJOLNIR Powered Assault Armor|Mark VI]] and [[Elite]] shielding.
===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}}


The Trip Mine spawns by default on [[Sandtrap (Level)|Sandtrap]], [[Rat's Nest (Level)|Rat's Nest]], and [[Avalanche (Level)|Avalanche]]. [[Jump Pack Brute]]s have been seen deploying the mines against nearby players in [[Tsavo Highway (Level)|Tsavo Highway]]. Destroying a vehicle with the Trip Mine in [[Campaign]] or [[Matchmaking]] will unlock the [[We're In For Some Chop]] [[achievement]].
==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}}


==Tactics==
==Gameplay==
*The most important thing to note when deploying a Trip Mine is to inform your allies. Unwary teammates may activate your Mine, resulting in a [[betrayal]].
*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).
*In Campaign, you should destroy activated trip mines as you leave an area, as marines are scripted to run certain paths, and if an un-detonated trip mine is in the way, they may simply walk over it, killing as many as three or four of them.
*A trip mine's distinctive beeping and orange glow makes it easy to detect.
*When fleeing an enemy vehicle, it may be wise to deploy a Trip Mine in its path. Such a move may kill the occupants of the vehicle, though it also poses a risk to the player trying to flee.
*The trip mine will only stay active for 90 seconds before spontaneously exploding.
*A Trip Mine is a useful counter to a [[Bubble Shield]]. Throwing a mine into an occupied Bubble Shield will almost always result in its detonation, and the resulting blast will be contained within the shield, killing only its occupants. If the explosion destroys the shield generator, however, it may "escape" the shield.
*Trip mines can be detonated from a distance by weapons fire, and are therefore only useful when unnoticed.
*If you deploy a Trip Mine on top of a [[Man Cannon]], the mine will go flying out into the battlefield. In the [[Halo 3 Beta]], the Trip Mine would sometimes disappear entirely when thrown into the Man Cannon. It would still explode if someone or something goes within the activation radius.
*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]].
*One of the most evil tricks, as [[Bungie]] has mentioned, is to deploy a mine in the exact position where it spawns. Some players will notice that the mine is armed, but many players will attempt to collect it, resulting in a kill (if the player's shield is almost depleted) which would certainly not have happened if the player was attentive. This tactic can easily result in a betrayal, however, so teammates should be warned.
*Trip Mines can be used to block doors, hallways, sniper perches, and other areas.
*If a player walks slow enough or crouch-walks over a Trip Mine, it will not explode.
*A Trip Mine's beeping tends to reveal its presence, but by hiding it around a corner or over a ledge, a player can prevent the mine's orange glow from compounding the problem.
*Throwing a Trip Mine underneath a vehicle will mask its glow, muffle its beeping, and turn the vehicle into a deathtrap.
*In [[Capture the Flag]], a player can place a Trip Mine by their own [[flag]]. It will kill any opponents that are trying to steal the flag. This tactic works very well when one flag gets the win; a good deal of players will be focused on getting the flag, so the Trip Mine would be ignored until it detonates.
*In multiplayer, [[Banshee]]s are commonly used to splatter enemies. If you happen to see a Banshee angling toward you and boosting, drop a Trip Mine. The explosion will probably kill both of you, but is usually still desirable, as Banshees are often hard to kill.
*On Avalanche, slip a trip mine under the most valuable vehicle at the enemy base, since they know it is underneath one of the vehicles, they will most likely take the [[Scorpion]], [[Wraith]] or [[Hornet]], resulting in severe damage or death.
*If a player has low shields and an enemy is chasing him/her, a good tactic is to throw the Trip Mine down. If the attacker comes around the corner, the resulting explosion will deplete their shields, allowing the defender to finish them off with a [[headshot]]. If the attacker hears the beeping and stays back, the defender will have a chance for their shields to recharge.
*If two players are in close combat and one is about to die, the losing player can deploy a Trip Mine right at the other player, as an act of vengeful suicide.
*Try making Trip Mines land upside down by bouncing off a wall or solid object, because they are much harder to see, since the light is pointed into the floor/ground.


==Disadvantages==
==Production notes==
*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).
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 equipment#Covenant trip mine|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.

*The shape of the Trip Mine resembles the German made [[Wikipedia:Teller_mine|Tellermine]] series of anti-tank mines developed and used during the Second World War; both mines are hand carried to their targets and are sometimes tossed into the way of an enemy tank in hopes of destroying it.

"A simple proximity mine that reacts to pressure or movement."
— Bungie.net stats description[3]

The TR/9 Antipersonnel Mine (TR/9 AP Mine)[3], commonly known to United Nations Space Command forces as the trip mine, "Tripper", "Skippy", "Automatic Guard", "Invisible Fence" or simply "Mine",[2] is a landmine developed by the UNSC.[1]

Overview[edit]

Design details[edit]

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.[2] Despite its flower-like appearance, the TR/9 trip mine is not the Lotus anti-tank mine.

Usage[edit]

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.[2]

Operational history[edit]

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.[1] Jiralhanae equipped with these mines were deployed during the Battle for Earth and Battle of Installation 00 in late 2552.[4] In the post-war era, Jiralhanae Jumpers allied with Merg Vol's Covenant also employed the TR/9 trip mines.[5]

Gameplay[edit]

  • 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[edit]

In earlier stages of development, the trip mine in Halo 3 had a Covenant-themed texture, featuring purple metal and blue lights. This cut variant can be found in the files of the Halo 3 Beta, though unused.[6][7] 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.
