It's a little esoteric, a good system but I was lookin for this guy -> to rep the Sixth Army and "fash", "fascist", "nazi", "wehrmacht" and others did not work
EDIT: he has "ustase" as a keyword, Croatian fash! Might as fuckin well be a nazi, close enough. As a bonus, NATOpedia claims that ~6000 Croatian Home Guard members served in the 6th army when it was crushed by Soviet forces.
