Do flying skirmishers, like Ripperdactyls, also have a spaced out formation? This is maybe an obvious question, but I've just always imagined them having a tight formation. Thanks!
... until they get into close combat, at which point you need to rank them close together like regular rank and file troops. It actually works to your advantage to have them spread out, at least for Terradons - it gives you a wider footprint for the "Drop Rocks" special rule.
