Yesterday I came up with this idea - but I don’t know if it’s possible to bring this into the game.
What about an event which is pretty rare - say once between 2 server restarts, that somewhere on the map will spawn a convoy (like the convoy wrecks) - but instead of standing still with a few zombies and loot spawning there will be moving cars or convoys.
For example: At some random time there will spawn 1 Truck 1 Humvee and 1 Sarka at tisy and it will cross the map down to balota or vybor and then move back and/or move up to the edge of the map where it will despawn. Each vehicle is full of npcs and drivable. If you manage to kill the whole or part of the squad you will be able to get all of a few cars and eventual loot in the cars or npcs (I don’t know if you could make npcs lootable). If you attack them they will stop and attack you or they will try to get away by driving faster. This doesn’t have to be military, could also be a simple civilian car or convoy.
It’s probably a really hard or even unrealistic thing to realise but It would be an amazing super rare event which makes a lot of noise because of the fighting.
One problem I see: if routes are blocked they may collide. So the cars might need something like a no collision model for the time they are driving.
