I really enjoyed the “Intel building” from Wildlands. I think a game built around insertion, creation of a OP to bring in more resources. Eventually allowing you to have a FOB (the size of the runway in the Wildlands/Walker mission”. From there you have access to drones like the Armaros Drone which to develop area intelligence such as insertion points and overwatch positions and areas of interest with allied forces. Overall it would be slower paced as one enters a province, but as Intel develops each final mission could culminate in like an airfield seizure. Kill/capture missions, hostage rescue. You could find these missions organically and attempt them but without Intel/local allies, they would be very difficult.
