well based on how many combat units I have drawn for  dusty I was trying to draw some more urban oriented, this is a CAT unit (Construction Assistance Techoid) a sturdy techoid designed for construction labor, it has strong armor and also his artificial muscles are capable of moving incredible weights, also its equipped with lots of tools, to avoid the use of the unit for evil purposes the CAT unit battery works for only 15 minutes and needs to stay connected in order to work for long periods of time.
