whoa whoa, I wasn't trying to start an argument over that, I'm on your side here (I'm an ork player afterall). Believe me, I was so peeved about the guy telling me it was models within 6 inches (which if CLEARLY not right since that literally ignores the wording of the power) I had to come on here and rant about it to vent.
My group of friends have decided to treat the KFF as a mobile cover. That isn't really as good as my interpretation, but it does mean they let units standing BEHIND the KFF get cover as well, which leads to some interesting circumstances. My personal belief is that if a model is within 6 inches, the unit that model belongs to gets the KFF benefit. However, I've gotta go with what the majority of the people I play with say or else we'll just spend the whole time arguing and that doesn't really make the game very enjoyable
