EDIT:
Big change this version is that artillery pieces are gone and Support Weapons are back to being Tarantulas. Oh, and Scouts are now wildly different. That's about it, honestly.
Explanation for changes can be found in the update post (much) later in this thread.

Fixed typo in Attack Bike unit entry, removed Scout from Land Speeder Storm, and revised the wording of the Support Weapons entry.
This'll be the last update for a while. I'm fairly confident in most of these changes, and the ones I'm not confident in other people are.
That, and I think it's time the list breathed for a while.Lies and calumny.
