Strategic Operations, p234:
If the aerospace Unit is attacking anything in the ground Unit’s hex, the ground Unit may attack the aerospace Unit at short range.
Do you still adjust the range for altitude as per the Ground-to-Air attacks section on p234?
I`m aware that you do for TW and the miniatures rules and the paragraph in Strat. Ops. p234 is a bit ambigious that could be read either way.
