well about giving the sniper a mosin nagant it does not have to be scoped, many snipers had unscoped mosin nagants though i don't think they were asigned snipers, they just sniped anyway.edit: though another way to represent the sniping without scope culd be to ad the sniper abillety brits have to the partisans meybe so for some munitions they will snipe a unit with a unscoped rifle.
dont forget the kar98k scoped
