I often will run a zeus mission over the top of an ALiVE mission, it works great.
Last time I just placed a helicopter wreck down, a couple of units scattered around set to unconscious and give them some injuries, then dropped down a couple of civilians and gave them the intel action using achilles and gave him a path up to and around the chopper. That intel told my guys that the civilian had seen taliban fighters take 3 hostages off to a nearby village.
Then I just cuffed 3 friendly units placed them in buildings around the town and gave my guys the mission.
I had to baby sit things in zeus to add a few more enemy forces and reinforcements but it worked well.
I also have a convoy supply side mission that I've been working on. I've got about 9-12 hidden markers placed in certain towns around the map. You head into one of the hangars and ace interact with a laptop and it spawns 3 crates of supplies and gives you the location to deliver them. Those crates will only fit in the HEMTT trucks (again using ace) so it forces the players to have to defend the truck while you deliver the supplies. Once they're unloaded at the target location the civilian hostility is reduced in the area.
That normally keeps us busy at least half the night if not all night depending on how much goes wrong.
