I don't see what people are complaining about with this DLC. This is the best DLC I have played so far in Arma III (haven't gotten around to all of them, but I definitely recommend this over things like Contact. Yes, it's a collection of short campaigns, 2 - 3 missions each, but they are all well written for singleplayer stuff. Yes, the AI can be finicky, but no more then the main game.
I thoroughly enjoyed replaying missions in different roles. The infantry missions did get a little annoying. Running across an open field with iron sights or something similar is definitely the start of a bad day, but that's the only thing that bothered me.
