I love the expression on both character's faces. Although, Nonna wins this round!
As it should be expected.
The CV.33, as the other tankettes (Carden-Lloyd, TKS, T-27 and Type 94), simply wasn't designed to go against armour; against anything that had even 15 mm of armor protection and a gun, it was simply overwhelmed.
Cause both tanks used in Spanish Civil War on different sizes. USSR suported Spanish Republic, Whil Italy and Germany supported The Francoists.
Anyway, Spanish tankmen had much lower qualification, which, in principle, reduced the advantage of some tanks over others, although the BT at that time was almost the best Medium Tank (no joking) in Europe.
