So as I beat my brain in coming up with all sorts of numbers (and also that phone app!), here is my biggest challenge:
Trained vs. Veteran
I consider this question to be the "Holy Grail" in FoW as an American player. Think Cobra, then ask yourself do you want the 2nd Armored or the 3rd Armored?
I am still working on the calculations on this.
[EDITORIAL NOTE: I am NOT this nerdy. Really. I promise.]
The competing interest here has to do with the point differences in the two forces and the fact that you are now 16.5% more likely to get hit by those pesky Germans. I am referring to the fact that the "to hit" on trained is 3+ and veteran is 4+. You then weigh that against the "but I can get more attack dice by having more units" argument.
In a tournament several months ago, I went CT instead of CV. The results were mixed. What I really noticed is that my AOP had a tougher time ranging in artillery. In fact, I would argue that the biggest difference in trained v. veteran comes in on artillery.
But our "guts" can be wrong. Just see the math on the one chance at a 5+ versus two chances at a 6. My gut says if you are running Cobra and you are using armored which will force you to almost always attack, go for the attack dice. But I could be wrong. So I am still trying to get the calculations correct.
Of course, any and all feedback is welcome here!
