I have (for the moment) two troop transports each with "Troop Capacity 50,000 tons". The highest level garrison unit, the Corps command with three divisions under them, is 70000 tons (due to having 1000 supply trucks). I would have thought that two such troop transports would, working together, be able to transport the unit. I expect now that is not the case, that no unit may exceed the capacity of a single transport. All the subordinate units they had under their command were just shy of 5000 CP/tons, and 'could' be transported.
I have no idea if it is possible to transfer some of those trucks out of that unit. Shoot, I'd settle for just deleting them. I cannot for the life of me figure out how to cause them to upgrade the build, despite reducing the number of supply trucks to 550 in the template and telling them to update, which would bring them under the 50,000 mark. I do NOT want to have to scrap the whole unit or have to build those STOs again along with new forces, they were freaking expensive!
Is there a video tutorial out there maybe that visually steps us through exactly what buttons to push to make this happen?
