Yes transports can load during combat movement and drop off. Assuming that they have the movements available.
I asked this on the A&A revised forum, but was reminded that that version doesn’t quite work the same way as A&AE works, so hopefully someone here can help me understand this better.
I was always under the impression that, as the defending player, your fighters take no part in a SBR unless the attacker sends his fighters as escorts for his bombers. If that is so, what is the attacker’s incentive to send his fighters along in the first place? It would seem to me that doing so would only serve to put his bombers at risk. We’ve played under this impression since Europe first came out….are we totally missing something? :?
