Passage: By 1942, light tanks were considered inadequate by the Red Army, unable to keep up with the T-34 medium tank and unable to penetrate the armour of most German tanks, but they could be produced by small factories that were unable to handle the large components of medium and heavy tanks.  The T-70 was an attempt to remedy some of the shortcomings of the T-60 scout tank, which had very poor cross-country mobility, thin armour, and an inadequate 20-mm gun.  It also replaced the very short production run of the T-50 light infantry tank, which was more sophisticated, but also much too complicated and expensive to produce.

Question: What type of armour did the T-60 scout tank have?
