I think I've located the discrepancy. On page 11 of bigger battles, at the bottom of the page, there is a list of firing modifiers and the only +1 modifiers are for Concentrated Fire, Large Target (vehicle or big dinosaur or such), and artillery/crewed weapon shooting at a Close Order unit. However, on the QRS, while the Large Target and Close order modifiers are listed, there is no Concentrated Fire - just "aimed" fire. I think this is a "misprint" of sorts or an oversight in editing. So, we should read "aimed" fire on the QRS as "concentrated fire".
So the win goes to Elk101, since only Close Order units can use Concentrated Fire.
And, Harry, perhaps the biggest difference between FFOL basic and bigger battles is that in BB, each unit only gets one "action" from my reading of the rules rather than the two actions in the basic or "core" rules. The only exception being as listed above for maneuver getting to move/shoot or shoot/move with the -1 modifier to firing.
If I am incorrect about only one action, please point me to where that is defined in the rules. I'm pretty sure it is just the one action, part of what keeps the game moving - and, frankly, in my opinion, makes for a little fairer game. Both versions still fun, though.
It is these little bits of difference that cause my concern with multiple variations of the rules. Not horrible, just at times confusing, especially if using multiple versions of the rules in near proximity to each other time wise, say BB in the AM and core in the evening.
For Jaye, if you read this - and I am correct in my analysis about the discrepancy, can we get a new and corrected QRS as a free download on the site, please? And perhaps clarify for us the two actions versus one action. I like the one action, makes the game move faster.
Cheers!
