Looking at the description, this is not "new" - it's the existing Uplifting Primer and the existing Munitorum Manual thrown together in a single book.
That said, I would recommend this to anyone who does not yet own them. They do conflict with
GW fluff a bit (obviously referring to technical details and doctrinal information, not the ludicrous propaganda on how weak the xenos are), but they are a very fun read and written in a very stylish, suitably grimdark manner. Excellent inspiration to get into the right mood for an
IG game, or a session of the Only War P&P.
For this price, it's a steal.
