Notes: This is a fire support variant of the Steyr 4K 7FA-KSPz armored personnel carrier. The basic chassis is topped with a turret mounting a 90mm French or NATO gun, and ammunition is carried instead of most passengers. Two passengers are retained as scouts so the vehicle can be used for reconnaissance. The top hatch is replaced by the turret, but all other hatches are retained, and two hatches are in the turret for the commander and gunner. This vehicle is used in small numbers by Switzerland and Greece.

Notes: This is a 4K 7FA KSPz armored personnel carrier modified to carry the Rasit ground surveillance radar and a computerized management system as well as extra radios and a datalink system to higher headquarters. The M-2HB turret is removed in this vehicle. The radar has a range of 30 km and may be operated by a cable at a range of 30 meters.

Notes: While the chassis of this light tank is of Austrian design, the turret is a modified form of that found on the AMX-13. The Kürassier, however, is afforded with a better night vision suite and better fire control than the AMX-13, and uses a 105mm gun as standard. The turret uses the same two-magazine system with 6 rounds each, and as with the AMX-13, the spent shell casings are ejected out of the rear of the turret. There are three light tank variations of the SK-105 in service; export customers such as Argentina, Bolivia, Morocco, and Tunisia mostly use the SK-105/A1; the SK-105/A2 is the version most commonly encountered in Austrian service; and the SK-105/A3 was the newest version, in limited production before and during the war. In addition, appliqué armor of the same capabilities as that available for the AMX-13 is available for the SK-105 (however, an AMX-13 kit will not fit the SK-105 and vice versa).
