Being a rabid Anglo-Saxon, I think you're overdoing the effect here.
With only a musket in hand, I can perceive the morale impact. With
automatic weapons, I'm not so sure.
And imagine how hard it is to hear "flower of Scotland" in the middle
of an artillery barrage.. The English fans manage to drown out every
visiting team's national anthem by simple whistles.
So, what about a pipes bonus card, whereby all sections within a
radius of the piper can move. Same as a German blitzkreig card, i.e.
they can't fire or spot, just go forward.
In terms of melee bonus, I would say that the Scots should be classed
as "agressive", as would other shock troops, as once in hand to hand
I'm not sure how much effect the pipes themselves would have. Perhaps
Germans of average and below fighting ability should have a
supression point inflicted if within a certain radius of the pipes?
