This probably won't happen. The easiest way for Bytro to circumvent German law regarding the use of Nazi iconography, which was a integral part of this historical timeline, was to remove the ability for anyone to change the flag and leaders name.
I like this, and even though it creates problems because of Nazi flags and stuff, I don't think the problem is too serious. In 3 years or so I played S1914, I only saw 1 reference to Nazism, and in CoW I've seen one, as an alliance flag. So I think it should be introduced. And if anybody DARES put anything Nazi, I vote for their account to be deleted, and no more accounts can b e created from that IP address.

That is why it should be optional to change the flag. Maybe we could have an option to change flags during the game, instead of before the round starts. Either way, you will still know what country it was.
I voted against the idea for many, many reasons. However, if this option were available only to High Command (HC) members and implemented only by a Game Operator (CoW Staff) upon HC player request; then I could probably change my vote.
