Campaign Series Mod to change platoon.oob

[Sean]

For Campaign Series WEST FRONT.

How can I limit visibility in a Scenario?
I noticed that some German Weapons fire 20 hexes and I would like to limit that to 13/14 to 16 maybe.
The USA weapons seem limited to 14 hexes so maybe that is a good number.

So can I limit visibility so the German Units cannot see the far targets?
And if so where do I make such a change?

I had a look at Scenario and Map editor and could not seem to find option.
Also looked at main.pdt and did not see an option either.
I could change the weapon.pdt ,but I would prefer not to edit lots of weapon lines.

Ideas?

Edit,
had another look at the Scenario Editor.
Under "Heading" ,
"Visibility" ,the scenario I was looking at , a random scenario ,had "1-16(20)" ,entered here.
I will change this value I think,
curious why it has a range and a value though.
