The jamming vehicle was a human vehicle that was used in the war with the Hierarchy. It was used to jam enemy targeting and sight.
The jammer was a mildly armoured and fast unit and could not attack enemies directly. Instead, it reduced enemy sight ranges, their targeting abilities, and made the closest thing the humans had to a virus.
the jammer was used in several unimportant battles against the heirarchy. Most were destroyed due to their lack of weapons.
