Not currently, no,
but,
you load all of your troops into it, it walks to the battle site and unloads the troops for 1UPT combat. What if instead of unloading, your stack inside the commander just had a combat with the stack inside the enemy's commander?
All I'm saying is that commanders are a potential vehicle for giving SoD-style combat as an option, for those players who might prefer it.
What if the enemy doesn't have their troops loaded inside a "commander" and instead just has them spammed all over their territory? Is there going to be some benefit to having the units inside the commander, other than movement logistics? Because if not, why not just bring back the SoD? Why the extra unit?
There are certainly tactical benefits to moving units separately in the 1UPT system. I have a lot of questions for how the commander is going to work in practice, but I guess we will just have to wait and see.
The way you are describing the functionality of a commander sounds alot like a transport... sort of like a Civ 4 galleon, but on land instead of in the water. I actually miss the water transport system of Civ 4 and I don't particularly like that units just insta-transform into boats whenever you move them onto a water tile.
Where did the boat come from? The army certainly wasn't carrying a boat around with them. Where did the boat go when they disembark back onto land? Why can't I, as an opponent, burn the boat so they can't escape?
Total War: Three Kingdoms uses a version of this (and pretty much disables Naval combat, other than mandatory auto-resolve with minimal animation), but you have to embark/disembark at designated pier/port tiles. Total War: Rome 2 uses distinct transport ships and warships, like Civ 4. I wonder if the commander in Civ 7 will also double as a giant naval transport.
One other thing that is nagging me about the commander system, is how the unloading works. So lets say I see a commander unit approaching, presumably loaded with units. Can I just swarm a bunch of unit spam around the commander unit to prevent it from having any tiles to "unload" its cargo onto?
Again, I know we just have to wait to see how it works, but I'm not that optimistic.
