brownfella@hotmail.co.uk 15 Posted July 25, 2012 (edited) If you buy Operation arrowhead and install with Arma II that is all you need. You do not need the Private Military or British Forces add-on to play Dayz. I suggest using sixupdater if you are not familiar with running mods. Hope this helps.EDIT: once you install armaII and arrowhead that is when it becomes combined ops. you cannot buy anything called combined ops.
