Thought I'd post my two pence worth.

As far as limiting the use of z fire I think the best course of action is to come to an agreement with your foe before starting a PBEM rather than adjusting the code which does allow for realism. I can think of two main "realistic" uses for it.

1. For HMG/MMG units.

Using mmg / hmgs to fire on a map location that they can't see is a tactic used in real life. I've seen a modern British Army SF (sustianed fire) platoon do this using 7.62 gpmg. By elvating the gun mount to the correct angle and using an equation to calaculate fall of shot or the beaten zone it is possible to use mmgs/hmgs to put suppressing fire onto the reverse slope of a hill etc that the gunners can not actually see.

2. To use any unit to put suppressing fire onto a location they can see that they susepct any enemy postions to be located eg treeline building etc. In game terms you fire at a hex in los that does not yet contain a visible enemy unit that has been spotted by the firer, but you think one might be there.

I have encountered PBEM foes who use a wide varitey of units to put up a wall of fire using z fire. In real life this needs the right equipment and more importantly the right knowledge to do this. Troops do not randomly fire all of their weapon systems into the air in the hope a few odd rounds might land in the general direction of the enemy. Its wastefull of ammo, it gives your postions away and you may hit friendlies.

To recall one of my old skill at arms instructors, "if you can't see it you can't kill it".
