The HRUNTING/YGGDRASIL Mark IX Armor Defense System, also known as the Mantis, is an armored fighting vehicle. It appears in Halo 4's campaign, multiplayer, and in a few Spartan Ops missions.


The Mantis is a powered exoskeleton armor defense system similar to the Cyclops. However, where as the Cyclops was designed only for labor and modified to function in combat, the Mantis was created specifically for combat as an evolution of an earlier model.

It is equipped with several weapon and defense systems, including armor plating, energy shielding, two weapon pods on either side of the cockpit, and a stomp ability. The weapon pods typically contain a machine gun on the right pod and a five-shot rocket launcher on the left pod, but these can be replaced with other weapons.


The Mantis is heavily armed and well-protected. With full shields, it is powerful enough to withstand a single Spartan Laser shot. The machine gun can shred infantry and the missile pod can demolish vehicles. The stomping ability will destroy almost every vehicle or infantry. It can also be air-dropped by D79H-TC Pelicans.


The Mantis is relatively slow and can be easily outmaneuvered by smaller, faster vehicles. The Mantis is also susceptible to being boarded from the rear by enemy players. Like other vehicles, it can be stunned for a few seconds using a fully-charged shot from a Plasma Pistol. After a stomp attack, the vehicle is unable to move for a few seconds, but the head of the vehicle can still turn and shoot. Its shield recharges slowly.
