Yet still making it difficult to move fast forward with the flag after you have dropped it and you have defeated some enemies. And by the way how to "choose battallion 1" for example when the flag is like that? Sounds complicated to actually make it.
just make it just like they do with the chainmail surcoats
6 different chainmail with different colored surcoats and one with heraldic pattern.
make 6 polearms with different flags and one with a heraldic pattern.
problem solved
