I recall reading that in the Rif War at least one inferior FT-17 tank of the oppressive bourgeoisie imperialists was taken out by a brave local anti-imperialist pushing a sword or long dagger through a weak spot (vision slit?) and to the capitalist lackey crewman inside. (There probably would not have been much room to dodge inside, even if you knew such a blade was aimed at.)
As far as I know, no T-18 was ever taken out by such attack, again proving the superiority of the Soviet design!
