Standard tracked APC of the Brick Isle Defense Forces.
APC development tested several different turret designs. The final two are pictured here.
The first turret is unmanned with 25 mm cannon and two antitank missiles.
The second turret is lower profile and contains only the 25 mm gun. While it is technically unmanned in operation there is ability to reload and service from inside more easily than the other turret.
Another key feature of the later designs is the two firing parts on either side.
In the field a long whip antenna is often mounted for improved radio communications.
Pictures below show gun-only turret configuration.
