Locust

"Locust" is the name applied to a series of Covenant quadrupedal mining platforms.

Summary
Locusts are quadrupedal mining platfroms that are part of a larger class of constructs known as Excavators. Out of nine tiers of Excavators they are classed tier-one on its scale.

Banished Locust

 * Banished Locust - The Banished utilize modified Locusts armed with unstable focus cannons, making them more dangerous than their Covenant counterparts.

Type-30 Locust

 * Type-30 Locust - A variant of the Locust seen during the Human-Covenant War.

Trivia
Like all known Excavators, the Locust is named after an insect rather than a supernatural entity like most Covenant vehicles. Locusts are members of the grasshopper family that are infamously known for rapidly stripping fields of crops. The walker's similar "building killer" usage may be the reason for the vehicle's name.
