The best I seem able to do is to force them to capture the planet, even if they have weapons (at least, I think it worked this way). Otherwise, the troop transport will just fire at the planet until it either runs out of ammo, or the planet has been fully glassed.

It will not be of much help to you, but... Capturing planets work fine when there is no treaty, and so the problem is likely of having both weapons (a Warship role) and troops on board the ship. You should be able to force the ship to act as a warship, or as a troop transport, but both during the same battle doesn't seem possible (unless I am missing something here).

I never mix mine BUT, if a person wanted to, why wouldn't a strategy with a primary movement of "Drop Troops" and a secondary movement of "Optimal Range" work on a troop ship with weapons? Seems like the game would move to try to drop troops (and if it couldn't due to not being close enough or platforms on the surface, it would revert to its secondary movement orders...Optimal range).
