You keep using that word. I do not think it means what you think it means.
Ahhh....my misspent youth...
This one seems easier to grasp than others I've tried and this example of play is very helpful. I had a couple of questions though...
That was my goal.
1. When a unit enters the map is that considered movement? So even if the unit didn't move beyond that first hex if it wanted to fire it would be considered assault fire?
Yes to both.
2. In example #3 towards the bottom it says, "The Germans decline fire and the decoy in G4 is removed as well as the conceal marker in H3." Why are the units revealed? Does it have to do with the reduced US unit in E5?
Yes, the American squad has LOS to them such that they are in open ground (no positive terrain modifier). They would also be removed if the squad was adjacent (even if it had a positive terrain modifier).
3. In example #5 if the German unit had missed its second Op Fire proficiency check against the now adjacent US unit would it still not be used? Still remain under op fire?
Yes to both.
4. In example #6 when the German unit attempts Final Op Fire its proficiency is reduced by one for moving in the open and adjacent. Why isn't it reduced by two
I meant one each - that is why the number they need to succeed is a 3. Their proficiency of 4 is reduced by one each so their prof is a 2. With a morale of 5, they need a 3 to pass.
