From Wikipedia
Stridsvagn 122 is a Swedish main battle tank that, like the German Leopard 2A5, is based on the German Leopard 2 Improved variant using such newer technology as command, control, and fire-control systems, reinforced armour, and long-term combat capacity. Externally, the vehicle is distinguished from the Leopard 2A5 by the French GALIX smoke dispensers, different storage bins, and the thicker crew hatches.
