I’ve thought about this a lot, and it could be implemented amazingly with both of these ways, , campaigns, multiple for if you want a story with the way you play, like using the Apache and little bird for air support, and black hawk for transport, along with both tanks having their own campaigns, such as invading enemy bases with the regular tank, and providing anti air with the SPAA tank, or you could put those two together, with the assault class it could be missions of raiding houses strategically to complete an objective, for engineer it could go with the vehicle missions, allowing you to attack vehicles with the rpg or talon, and repairing vehicles that you are in, for medic it could be providing support with an assault type mission and healing any fallen teammates, and recon letting you spy on enemies to give information to HQ, with all of these being co-op or single player, along with a big campaign consisting of everything, I personally think it would be an amazing addition to the game
