The Razorback combines the engine of a pre-Schism prime mover with a tracked rear unit, reducing speed and economy but greatly improving offroad performance. Further modifications vary depending on intended roles; some Razorbacks are more heavily armoured, others are more heavily armed, and others again are stripped down to increase their carrying capacity.
- Razorbacks use diesel engines which originally pulled road trains of 100 tons or more. A slightly shortened camshaft powers the tracks via forward drive wheels. As the front wheels are used for turning, drivers need no special training, though unlike fully tracked vehicles Razorbacks cannot turn on the spot.
- The cab-behind-engine layout is preferred for combat vehicles as it offers drivers more protection; the cab is also more easily lowered and armoured. Prime movers with cab-over layouts are more commonly used for civilian roles.
- The sleeping compartment formerly fitted behind the cab is replaced with a weapon mount. The open-topped barbette seen here provides less protection than a fully enclosed turret but better visibility. The main 75mm gun is used against hard targets; the 12.7mm machine gun is used for close range defence.
- The rear tray is also open-topped but its armoured sides and tailgate shield its occupants and cargo from low-trajectory fire. The external perforated plates add another layer of protection and can be used as anchor points for tarpaulins and/or extra gear.
- Though Razorbacks are more resilient than most wheeled vehicles, their large size and high profiles leave them vulnerable to pre-Schism armour and weapons used to counter it. Razorbacks usually work in tandem with lighter, faster vehicles equipped to deal with aircraft, tanks or rocket-equipped infantry.
