Multi-Tasking Machines
Although there official name is unknown, Johnson saw these in the Harvests capital city of Utgard. They are a series of JOTUNs that are capable of doing a large variety of different things.

Prototypes
One of the prototypes was on a Human freighter, This End Up, commanded by Henry "Hank" Gibson, who was killed in the resulting fight with the Covenant. When the Covenant attacked the vessel, the Huragok Lighter Than Some saw the prototype and built three vehicles based on it that would be later known as the Type-25 Rapid Assault Vehicle, which is also known as the "Brute Chopper". It would later see service with the Covenant and the loyalists by the commanding officers of the Covenant Army, the Jiralhanae or Brutes.

The machine Gibson was carrying was a massive machine designed to till wide swaths of earth. It has six massive wheels and a large beam with spikes on the front to carry around the earth.

Others
There is little or nothing known about JOTUN's Series 1 and 3 machines.
