This is the Unmanned IFV dubbed 'Project Ocelot' in tracked config with some slight differences.

It now carries a L55 version of the gun, as the tracks provide a platform able to handle the more powerful version of the gun.

It looses some speed and range with the tracks, but added mounts for external fuel tanks can double its fuel capacity and range.

Emergency lighting (Project Ocelot isn't just a front-line fighting vehicle. so both versions offer lights and siren to warn people to move in a civil environment, The tracked variant has a metal cover on the top of the lights, making it less noticeable from the air)

I Made this a separate image as to not cause more confusion then necessary for people who have already seen the 6x6 version, and as the vehicle is easily changed between both if needed.
