The Stridsvagn M/41 SII was a Swedish licence built Czech TNH medium tank. The M/41 SII was part of a second batch of tanks ordered in June 1942 which featured an improved engine and thicker frontal armour compared with the SI although it was armed with the same 37mm Bofors M/38 gun. The last 16 vehicles were converted into Stormartillerivagn M/43 armed with a 75mm gun. Production of the SII stopped in 1944 after a total of 106 SII had been produced.
