The Aptrax was designed to be the APC that would typically be carried by the Enforcer landing craft.  The main design limitations were the width and the length.  In addition I wanted the finished design to have a 'low clearance' look similar to the APC in the movie Aliens.

The resulting design came out looking like some sort of heavily armored car.  The Aptrax has one driver and enough space for 5 Blactron soldiers (6 in a pinch).  Other features include a rotating heavy blaster turret in front and a grenade launching array in the back.
