So I really am aware that this is a game first and foremost but on the subject of command units in a long range unit how accurate is the inclusion of musicians and standard bearers?

I am a fan of history but certainly not a professor on the subject(hopefully one of you are) and I can't ever remember hearing about standards or musicians being used in units of bowmen.

So realizing that this is indeed a game does anyone have any issues with command groups in archer units for fluff purposes?

Those with little regard for fluff Im sure will not but for those who do what is your opinion and am I wrong and were standards and music commonly used to inspire units of archers on the battlefield?
