Notes: The S-Tank is a radical departure from normal tank design. A Swedish MBT, the S-Tank is fully amphibious and has a very low profile since it has no turret. The suspension causes the vehicle to elevate and depress the gun and the S-Tank is able to pivot 360º very rapidly by track movement. A dozer blade is standard equipment and can be used to clear obstacles and blow mines. (Any hull front hit is 50% likely to hit the dozer blade, which has an armor value of 10 and acts as spaced armor). The S-Tank has two engines, one diesel and one gas turbine; the diesel is normally used on roads and the less economical gas turbine is used cross-country and in combat for better power response. The driver sits to the left of the commander and doubles as gunner, meaning that only a very skilled driver/gunner can fire on the move. The commander has a weapons mount by his hatch on the right center deck (NMT). A radio operator sits behind the driver and can also double as gunner if need be. The S-Tank is amphibious with preparation; a large fording screen must be erected, taking a 15 minutes. The main gun is noteworthy; it is a 105mm rifled gun 62 calibers long.

The Striv-103C is the only known variant; it is somewhat larger and has "fencepost" armor on the front of the hull to predetonate HE-type rounds. This provides the equivalent of spaced armor, but only for the upper hull. It also has a more powerful diesel engine and two Lyran smoke mortars.

Notes: This Swedish tank is a Leopard 2A5 that has been put through a significant upgrade program. Key improvements have been made in armor protection, night vision, and fuel economy. The vehicle is otherwise similar to the Leopard 2A5, but the armor on the hull front, turret front, and turret sides has a distinctive wedge shape.
