I believe no ultimate unit is affected by vehicle/air upgrades, but there are many other units I am confused about.
For example, the mini scarabs that the hunter leader makes…do they count as infantry units or vehicle units? Do they even get affected by upgrades?
Anders sentinels, do they receive air upgrades?
Sgt Johnsons Walkers, are they all effected by vehicle upgrades?
Hero units, do they receive infantry upgrades? What if its Sgt johnson in his walker, or forge’s vehicle?
Is there any information out there that lists what is affected or not affected by all upgrades?
