I love Czech engineering, and this is a fascinating beast. The 30mm twin anti-aircraft turret is a stand-alone unit that drops onto the truck body, that is specifically designed to accept it. The chassis is a 6x6 unit that uses offset-hub final drives, that gives excellent ground clearance. Think Unimog. The 6-wheel-drive system uses two of the same rear diff/axle units, eliminating the need to pass the drive through the middle diff. All the important bits are tucked neatly away under the armour. On top of all that, it's a good looking unit!
