Rules for the use of "z"

[roman]

In another thread there was talk of restrictions on the use of "z". Said to be a gray area but I think you can get to agree on basic criteria. I never had problems with that until I played with Mr. Z :).
I think we can use two lines of approach.
a) use in attack
b) use in defense

a)
1) can shoot with "z" only with machine guns and artillery support.
2) The infantry can only fire suppression fire on targets that have been identified and covered with smoke. (z is a good countermeasure against the smoke)
This is an important point because it is difficult when a whole company enemy hits you with the z. It becomes a senseless shooting. It could put a maximum number of shots.

b)
1) equal to b 1
2) equal to b1. You can shoot with infantry when this is pinned by enemy artillery fire. Although the enemy is not covered in smoke but is covered by the field.


It's just a suggestion. Together we can make this clear dark.
