Stridsvagn m/39 and m/40 light tanks
Sweden did not possess a large tank force at the start of WWII and the m/39 tank (entering service in 1941) was the newest she had, despite only 20 being built. It was very similar to the earlier m/38 (based on the L-60 of 1934). In 1941 the provision of bolting on 35mm of additional armor plate to the front during wartime was added; this became known as the m/40. However, since the extra weight caused faster wear on the tanks, the armor was not fitted during peacetime.
The Stridsvagn m/40 has a crew of three. The commander sits in the turret and loads the cannon. Also in the turret is the gunner, who fires the cannon and MG. The driver sits in the body. The commander manually traverses the turret at 3 degrees per second. The m/40 uses 4.8 gallons per hour at routine usage.

Design Notes
The design weight was reduced 7% to match historical weight and gSpeed
was reduced from the 34mph design speed. Chassis cost, weight and HP
were divided by two. Turret armor is Expensive.
Without the added armor, frontal DR is 6o and weight 8.7 rons.
