What Smed and Von Luck said....
One more thing...the rules explain this but not very clearly.
Global OP fire and Individual OP fire settings.
If they conflict, the game will default to the shorter setting between the two.
So...if you want units to fire individually and as you set them to fire...you should first click on an empty hex....and set everything on the OP fire window to LONG.
Then...go to your individual units and set them as you desire and they should shoot when you tell them to.
One further question for the real grognards out there....if you have an AA unit and you turn it OFF for soft targets/infantry/etc...will it still trigger on an air attack at the beginning of a turn? This matters to some of us...so stop laughing...(:O)
If Smedley, Von Luck, and Umbro don't know we may have to resort to the Jason for the "final answer"....
