Alternate Artillery Rule

[Mr Grumpy]

this rule looks to have a major impact playing the Russians in Kursk - playing through one turn of the North battle, I inflicted roughly 1600 German casualities with artillery fire using the alt rule vs. under 800 with the normal art setting

Would think that the ability to aim Katyushas on a specific target within a 1KM square would be limited

That is the effect of this rule, it is down to the player (knowing this rule is in effect) to not stack a huge amount of units in any one hex, the fact you caused 1600 casualties suggests that hex was packed tight with troops.
