Panzerbefehlswagen (command tank) III ausf E or F in Greece, fitted with a 37 mm gun and two coaxial machine guns (1940).
Yes, who is that guy on the back of the tank? looks British or Greek.. heres more info.
This is the same prisoner showned in "Panzerbefehlswagen III", but a photo taken from a diferent angle. Scanned this photo from a old book I have (from 1968), much lower quality when compared with the first photo but a curiosity nonetheless.
Two Pics in one.
