The Panzer II was designed before the experience of the Spanish Civil War of 1936-39 showed that shell-proof armour was required for tanks to survive on a modern battlefield. Prior to that, armour was designed to stop machine gun fire and High Explosive shell fragments.The Panzer II A, B, and C had 14 mm of slightly sloped homogeneous steel armour on the sides, front, and back, with 10 mm of armour on the top and bottom. Many IIC were given increased armour in the front. Starting with the D model, the front armour was increased to 30 mm. The Model F had 35 mm front armour and 20 mm side armour.
