The old Heavy Support slot used to be only slightly less of a no-brainer than the old Elites slot; two squads of XV88s and a Hammerhead, with the number of the former depending on the size of the game. Enough has changed, though, that it's not always so easy to decide. And, as Martha Stewart used to say, that's a good thing.
I just have to say this; the opening to Dredd is awful. It's just really, really bad. It consists of a freeway chase and a mall shootout, and while the action is decently staged, it in no way, shape or form looks like the kind of world Judge Dredd should be operating in. It looks like it's taking place in a particularly rundown section of contemporary Los Angeles. It's about as underwhelming as an opening can be, really.
Which is annoying, because the rest of this movie is pretty great.
