It looks like you'll have to buy 3 Agressors in order to have all the 2-ship combinations though...
Huh?
Not enough cardboard inserts, is my guess. Assuming FFG only gives you two per pack, then you'd need a third pack to field both of the IG variants that are on the obverse/reverse of a given insert.
Edit: But I don't think that's it either. With two packs, you get two copies of each tile, which means you don't run into that issue, right?
