Also can other assets be used, especially those that are local? In Caucasus for example, redfor can use both the A-50 and the KJ-2000 Awacs. Whereas in the PG map, they can use the Iranian A-50 Adnan Awacs.
Another good example is when a base is captured, the cargo plane coming to deliver the SAM sites and other systems can be local to the map as well, like an Iranian IL-76 or C-130 for Redfor in PG map, while the C-17s or C-130s for blue could be Kuwaiti or UAE
