Hi,
On the GW site you can download the complete Armada book. It is available as seperate pdf's. (Starts with To Cleanse the Stars, last one is To Unite the Stars, oh and the pdf beneath that, with the scenarios etc).
You will only miss 2 pages of the book. These contain attack ratings & reserve rules. But this page is available on this forum in a thread by me.
And the FAQ2010 also contains that information.
FAQ2010 is not yet official. Will be. We hope.
