The '''TR/9 Antipersonnel Mine''', otherwise known as the '''Trip Mine''' or '''Mine''', is an [[UNSC]] [[Equipment]] item usable only in [[Halo 3]].
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 activated by proximity, or impact of a [[vehicle]] or personnel. 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. The Trip Mine cannot be deactivated once deployed, but it will explode after about ninety seconds if it's not triggered. However, it can be destroyed by any weapon.  There is no device that can remotely detonate the mine. The Trip Mine, while having a larger blast radius than a [[Frag Grenade]], will only slightly injure a [[Spartan]] or [[Elite]] when they are positioned, near the edge of the blast radius. It will; however, kill [[Brutes]] and unwary [[Marines]], even if they are on the edge of the blast. The greater damage to Marines and Brutes may be due to the fact that their armor is weaker than the Mark VI and Elite shielding. The fragments will slip through their armor, thus killing them.
===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]].
It is possible to avoid detonating an activated Trip Mine. Notice that when a player crouches while moving forward, he or she doesn't show up on the motion tracker.  So if a player is crouched, that player can safely bypass the trip mines.


The Trip Mine spawns by default on [[Sandtrap]], [[Rat's Nest]], and [[Avalanche]]. Destroying an enemy vehicle with the trip mine in [[campaign]] or [[multiplayer]] will unlock the "[[We're In For Some Chop]]" [[achievement]]. Brutes with jet packs will deploy Trip Mines if you are close by. In multiplayer, a single Trip Mine is incapable of killing a player, it will only injure them. On foot, a player must have two or more Mines available, to kill someone with a full shield without the assistance of a weapon or grenade. This is impractical because a player cannot carry multiple Trip Mines, and the player's victim will most likely avoid a second Trip Mine. Vehicles that use   
===Usage===
anti-gravity ( [[Ghosts]] and [[Wraiths]]) can also be damaged or destroyed by the mines.  A vehicle that doesn't touch the mine, but gets close can cause it to detonate.
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}}


Also, in multiplayer maps, Trip Mines can be used as part of a known [[glitch]], commonly called overloading a map, to disable certain parts of a map, such as [[Gravity lift]]s, [[Man Cannon]]s, [[Brute mine|Sandtrap's minefield]], and [[Snowbound]]'s [[Automated Plasma Turret|Automated Turrets]]/ guardians.
==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==
*When running away from an enemy vehicle, a Mine can be deployed in front of the approaching vehicle. This may kill the occupants of the vehicle, but it carries the risk of killing the player who deployed it.
*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).
*Try to combine the powers of the Trip Mine with different pieces of Equipment to make interesting effects. For example, its useful to drop a trip mine into an enemy [[Bubble Shield]]. The resulting blast will be contained within the Bubble Shield, killing your opponent but keeping the player who deployed it from receiving any damage in return.
*A trip mine's distinctive beeping and orange glow makes it easy to detect.
*If you deploy a Trip Mine on top of a Man Cannon, the mine will go flying out into the battle field. Throughout 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 will only stay active for 90 seconds before spontaneously exploding.
*One of the most evil tricks, as [[Bungie]] mentioned before, is to deploy a mine in the exact position where it spawns. Some players will notice that the mine is armed (by noticing its distinct audio and visual cues), but most players will attempt to collect it, resulting in a kill which would certainly not have happened if the player is attentive. However, this tactic can kill teammates, it is wise to communicate with them beforehand.
*Trip mines can be detonated from a distance by weapons fire, and are therefore only useful when unnoticed.
*Trip Mines are the only equipment currently in multiplayer that can directly kill enemies.
*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]].
*Place Trip Mines in doorways or Sniper perches, someone will step on it eventually.
*Throwing a Fragmentation Grenade at a Trip Mine can cause extra damage.
*If a player walks slow enough or crouch-walks over a Trip Mine, it will not explode. Although you are doomed if any enemy sees you doing this.[[Image:Tripmineexplosion.jpg|200px|right|thumb|The general form of a Trip Mine's explosion.]]
*The Trip Mine's glow and beeping sound gives it away (as mentioned in disadvantages), although, it can be placed on the one side of a hill, as an example, so the driver of a vehicle will still hear it, but not see it as they are passing from the other side. The Trip Mine will detonate when the vehicle passes over the hill.
*Another tactic is to throw a Trip Mine under a vehicle, so it is harder to see and the sound is muffled. When a player moves while in the vehicle he or she will activate the trip mine. This works especially well on enemy aircraft.
*In [[Capture the Flag]], a player can place a Trip Mine by their own [[flag]]. It will kill any opponents trying to steal the flag. This tactic works very well when one flag gets the win. A good deal of players are focusing on getting the flag, so the Mine would be ignored until it detonates.
* In the level [[Tsavo Highway]], Trip Mines are a useful way of destroying the [[Brute Chopper]]s by throwing it at the Chopper once it starts charging at you. They are a one hit kill on lower difficulties, allowing players to unlock the "We're in for some Chop" achievement. To make this easier, a [[Plasma Pistol]] overload can be used to disable the Chopper. When it is stationary, a Trip Mine can be placed right in front of it, guaranteeing death for the enemy.  
*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.
*If a player has low shields and an enemy is chasing him/her, a good tactic is to throw the Trip Mine down. So when the enemy comes around the corner, it will explode, taking down his/her shields. He/she can then be finished off with a shot from a [[Battle Rifle]]. If the opponent hears the beeping and doesn't come around the corner, it gives the player chance for your his/her shields to recharge.
*Always remember where you left your Trip Mines and tell your teammates as well to avoid betrayal
*If you deploy a Trip Mine on a occupied vehicle, it is possible for it to explode immediately either destroying or disabling the vehicle. But it's most likely to kill you also.
*A single Trip Mine can kill a player, however it will generally only completely lower their shields.
*It can be thrown straight at a players face at point blank as a sacrifice if your shields are down.
*Trip Mines can be bounced off overshield powerups
*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.
*The mine is effective against running brutes,or ghosts, but it is good against all vehicles.
*A Trip Mine plus a fragmentation granade is an effective way to take out that annoying bunny-hopping camper. Just throw the Mine, toss a frag, and watch the beautiful fireworks.


==Disadvantages==
==Production notes==
[[Image:19499384-Full.jpg|200px|thumb|right|An inactive Trip Mine.]]
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. If the vehicle then moved, the mine would explode, killing all players inside of it.
*Sometimes, while playing in multiplayer or campaign, you can either accidentally run, or drive over your own self-activated Trip Mines or in [[Co-Op]] you can obliviously run over your teammate's Trip Mine. Without proper communication, you may also end up killing your own teammates with this device.
*Be aware about where you are tossing the Mine and don't forget its location.
*Players can be clever and use their enemy's Trip Mines against them, by luring them into the blast radius.
*It is easy for an enemy to see a Trip Mine, that you have deployed due to it's glow. Additionally it makes a distinct beeping noise.
*While it could instantly destroy vehicles in the Beta, it now only takes down shields; however, for whatever reason, most riders in a vehicle will be killed by directly driving over a Trip Mine in the final version of Halo 3, even though their vehicle may suffer only minor damage.
*In high ground the trip mine can be used to barricade the openings in the base, namely the knocked down wall and small hutlike building on the western side outside the base.
*The Trip Mine is fairly small, so vehicles could easily evade it but if the vehicle evades it but is close enough, the mine will explode.
*The Trip Mine will only stay active for 90 seconds, so if you have a place wired with Trip Mines they might go off before another player steps on one.
*Although powerful in the Halo 3 Beta, the Trip Mine was significantly reduced in power in the final release. Dispute and unrest about this change still continues on the Halo 3 forums.
*If shot, the trip mine will explode, which makes it easy to avoid if you shoot it from a far enough range.
*The Trip Mine is often difficult to use in split-screen local games due to the sound it makes when deployed, alerting the other players to "screen peek".
*As depicted in th Halo 3 weapon overwiew from Machinima's very own SoDaGod, the Tripmine is like a "ninja with headlights". This is because the trimine can be heard before seen or vie versa.


== Trivia ==
==Trivia==
*Even though it's said that this is [[UNSC]] equipment, the [[Brutes]] with jet packs always have one ready to use and no [[UNSC]] Marine/ [[ODST]] has been seen holding one.
{{Linkbox|gameplay=yes}}
*It was hypothesized that the Trip Mine may be the book-aforementioned [[Lotus Anti Tank Mine]] or they may be both made by the same manufacturer. However, it is unlikely the Trip Mine is the Lotus Anti-Tank Mine because a [[Scorpion Tank]] can easily drive over a Trip Mine and survive the explosion. It is possible that the Trip Mine is the [[Antlion Anti-Personnel Mine]] due to its similar operation.
*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]].
*The Trip Mine along with the [[Power Drain]], is the best equipment choice to get the achievement "[[We're in for some Chop]]", as it can easily destroy a [[Brute Chopper]] with appropriate effortlessness.
*Trip mines can be used to [[Overload glitch (Halo 3)|overload]] a map or [[Flying Elephant|launch an Elephant]].
*The Trip Mine logo, along with the [[Bubble Shield]] logo is a [[Halo 3]] Multiplayer [[emblem]].
*Trip Mines can be used to overload a map, deactivating certain parts of the map, such as the Automated Plasma Turrets in Snowbound, the [[Brute Landmine]]s in [[Sandtrap]], or the giant lifts in [[Blackout]], [[Guardian]], and [[Construct]]. To overload, you must place a great deal of trip mines through use of a glitch. After many are placed, all you have to do is shoot them!
*During the initial unveiling of ''[[Halo 3]]'', a [[Bungie]] employee claimed that, "The Trip Mine is probably going to be used as a 'I got you' weapon as people only seem to drop it right before being splattered".{{fact}}
*It's nearly impossible to kill [[Jackal]]s with a Trip Mine because Jackals fight and move in crouching positions.
*You can throw a Mine down on an opponent and follow with a grenade or a headshot for a guaranteed kill with normal shields.
*In the [[Halo 3 Beta]], deployed Trip Mines could stick to the bottom of a motionless vehicle. If the vehicle then moves, the Trip Mine explodes, killing all players inside with normal shields.
*It is possible to traverse a Trip Mine if one crouch walks over the top. Note however, that this only works if you are moving slow enough as to not appear on radar.
*Sometimes, a Trip Mine will fly straight forward so if you throw it into the air, it would disappear eventually like any bullet or projectile.
*It was described as a "Ninja with fog lights in his pockets" and the fact that you had to hide it, or people would see it by Sodagod in his description of ''[[Halo 3]]'' Equipment on the web series Inside Halo.
*After 90 seconds the Trip Mine will engage in a different "alarm" noise right before it automatically goes off.
*You can kill a pack of [[Brute]]s with a single Trip Mine.
*The Trip Mine is a great way to kill [[Covenant]] troops because they are always moving around. Try to throw them into large groups.
*If you set it off, while looking down at it you will see your body split in half for a moment.

"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.
