This is an armor addition to the basic I-07 GA unit ( [[link] ) Basically the armor is just worn like regular armor on top of the basic exoskeletal frame of the GA itself. This specific modification is for long range combat and sniping functions. Its fixed railgun is a product of experimental railgun technologies gone right. the railgun allows free movement of the GA's arms and manipulation of external objects and weapons. The chest piece does restrict movement but it compensates by performing additional functions; such as recoil compensation, walking, running, target acquisition, communications, etc. This unit still utilizes its original thrusters along with additional jump jets to allow long range jumps. They're known as thumpers to the enemy, and archers to allied forces.
Performance: Land- 50~ mph Marine- Take off only. Underwater functions nonexistent Air- 200 MPH (Through jumps. Sustained flight impossible.)
And this inspires me ideas for my 'roboxers'
