Wherever it's impossible to build a Chimera Core, the engineers of Epsilon Headquarters just take one of its heads, mount of on a small 4-wheeled buggy, add some navigational control mechanisms and call it a Hazequad. They then send these drones into battle zones in order to have them deploy and generate a psychic illusion field of a decent size, enough to turn HQ's units invisible and prepare an ambush. The Hazequad's presence is not concealed, though, so it will most likely be the first target of an enemy attack. It might be wise to deploy more than one at a designated position.
The Hazequad can be used as a substitute for the Chimera Core defensively: the cheap cost, ability to relocate and lack of power and ground control requirement at the cost of smaller radius and weaker health allows these mobile stealth generators to be amassed in greater numbers as part of Headquarters' doctrine to shroud their forces.
Multiple Hazequads that are deployed to maximize their radius' effectiveness can also be used by a proselyte to hide their forces as they advance in the battlefield towards an undefended base or an unprepared strike force.
It may also be used as a decoy against ground assault, airstrikes and support powers.
