You will get this achievement by completing any 18 different co-op missions with someone else, on any difficulty. To get this quick, you can just do the first 6 mission of every campaign on easy, the last 3 are most of the time the hardest.
Playing with someone else makes the mission a lot easier, because normally you get a computer as ally, and that's pretty hard to work together with.
