The example on page 9 covers that exactly, I think.
Example: You declare that your A-10 will attack Units in the Hex directly in front of the A-10. GBU-12’s can attack Units in that Hex, as well as Units in the same Hex as your A-10.
Ah geez. Guess I should read the examples huh. That's the trouble when all the rules are new. Sometimes you don't see the forest for the trees. I completely missed that. Thanks again.
