The only new ship we have seen on one side is a troop deployment ship and nowhere in the original trilogy do we see that side deploy troops from a ship. I could see it an hanger or something but it doesn’t make sense for it to appear in combat.
The only time troops are deployed is in ROTJ and that’s with an Imperial ship (the wrong kind but that’s a different fix).
Oh, of course. We definitely don’t need a new scene where Rebel troops are landed. If it were to happen, just having it stuck in a hanger or flying along with a fleet or something would suffice for me.
