Covenant Mine

Thought not an official name, the Covenant Mine can be seen on the multiplayer level Sandtrap. If the player runs out of the map's border, these mines will automatically eject themselves from a buried position, fly vertically about 2-3 meters above the ground, and detonate in a manner similar to a UNSC M9 Fragmentation Grenade. The mine itself looks much like a Brute Spike Grenade without a handle, 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 with explosive energy. The mine is useless against aerial targets, because it will explode only a relatively short distance above the ground. It terms of story value, the mines may have been set up by the Brutes to form a defensive perimeter around the Forerunner artifacts they were digging up in Sandtrap.
