More than that, it seems a logical solution to solve the effect of people running backwards to avoid a stab. Now you can run faster than they can backstep
AND it works wonders for byonet charges, which I will suggest shortly....
Ok, you forced my hand
When byonets are selected, allow there to be a single commo-rose option like with grenades, for commanders it's CHARGE, and for anyone else it is CHARGE, but tied to the only charge option that goes 'AAAGH!', or DEUTCHLAND!!!.
People actually do fear charging knifemen, and this can be best used in mass charges for squads as a feasible tactic against an enemy also wielding rifles, or even smgs. With shouting added, it will certainly make them fire amiss... But yer, it will be a desperate strategy.
