Jumpmine

Though not an official name, the Brute Landmine can be seen on the multiplayer level Sandtrap. If the player moves outside of the map's border, these mines will automatically eject themselves from a buried position, rise vertically about two-three meters above the ground and detonate in a manner similar to a UNSC fragmentation grenade.

These mines are located on Sandtrap and have a dual function of keeping people from entering and exiting the temple area. The mine itself looks very similar to a larger version of the Brute Spike Grenade, without the handle or the three main spikes on the top edges, and is extremely effective against vehicles and infantry.

Since the mine is designed to explode above a target, it can shower the crews of vehicles like the Mongoose or Prowler, or regular infantry that are foolish to venture into the minefield, with explosive debris. The mine is less effective against aerial targets (because it will explode only a relatively short height above the ground) unless the player is flying relatively low to the ground. The mines can hurt players even if Invincibility is turned on, if they are in a Bubble Shield or behind a Deployable Cover, similar to the Automated Plasma Turrets in Snowbound.

Trivia

 * If by chance a player finds a spot outside the perimeter where they aren't tripping the mines, they can see that the mines aren't entirely buried, as the top of the mine's heads can be visible in sparse groups of five or six.
 * Only some vehicles can outrun the mine's blast, these being the Warthog, Ghost (with boost), Chopper and the Mongoose.
 * Two direct hits from a landmine will kill a player when traveling across the mine field on foot, with the first one taking down the shields and the second one delivering the killing blow.
 * When the player speed is turned up beyond 200%, a player can easily outrun the mines' damage radius. When the player's speed is 300% and the player's gravity is 50% they can outrun the mines with even more relative ease.
 * When high above the minefield, the mines will still come above ground and explode, but because of the mine's short jump height, it can't hurt the player unless they're really close to the ground.
 * Overloading the map with Trip Mines will prevent the mines from popping up and harming the player, though it is possible to randomly come back. The absence of the mines is only limited to the current game being played.
 * The mines make the exact same noise as a Frag Grenade when exploding.
 * The mines are activated by a thin orange beam, which is fired from one of the Easter Eggs in Sandtrap. The beam is commonly mistaken for a Sentinel Beam.
 * They will stick to the bottom of vehicles and will slightly curve towards them, hinting at the mines being magnetically driven.
 * The landmine bears similarities to the WWII-era S-mine, more commonly known as the "Bouncing Betty".
