I heard their was a paper on the effects of single fire and stack fire to the effect that firing guns one at a time was better. Dose any one know about this?
In the game individual fire usually results in higher casualties than stack fire. It has been a long time since I saw a full evaluation of the two means of firing so I can give the actual numbers. It basically has to do with how the game creates a minimum and maximum kill numbers and generates the random casualty number. It has mostly to do with the minimum number. It can't be negative. So if a stack of units say five generates a 0-25 possible kill if fired as stack, the individual fire might cause more casualties because they might have individually 0-10 range. The reason being that the minimum got cut off at 0.
Here I am going to say "trust me" because I am to lazy to run all the math to prove it.

With large fire stack, large in that they produce fire ranges of say 100-200 range it statistically doesn't matter but my random rolls then to be snake eyes so I usually fire individually anyway to average out the bad luck.
There is one big exception. Artillery. Because when you fire at artillery it is all or nothing, you either hit or miss entirely, you want to maximize the fire against it for each roll of the die.
