The "shoot on the move" fix only impacts older tanks (the setting is by weapon by vehicle, so a vehicle may, concievably, have some fire on the move weapons (like MGs) and some stop-to-shoot weapons, like main guns.

The effectiveness is handled. It is set in the game rules, so that each scenario can replicate different unit training levels and effectiveness.

Weapons either do, or do not, fire on the move. Your vehicls will not take "pot shots" when they know they can't hit (unless you set them to suppress a target area).
