For those looking for holiday reads and last minute gifts I recommend the following two items:
1. Fighter Combat: Tactics and Maneuvering, by Robert Shaw
http://astore.amazon.com/jas5-20/detail/0870210599
This is mentioned in our J5 training manuals as a reference and recommended read. While a bit dry, it is absolutely worth the time and effort - I'm actually reading it while I'm away for the holidays. It's particularly good because it explains how the different tactics can be combined together in succession to change the nature of the engagement. I see a lot of fights where pilots get stuck into a level or slightly nose down turn and just sit there hoping to win the turn for a guns tracking shot. I used to do that a lot myself, and then a wingman or a latecomer to the fight would come down and bag me if my opponent didn't outturn me himself. This will help you figure out ways of breaking out of situations like that and ending the fight quicker so that those annoying Spads and such don't have time to come down on you unawares or just line up for a pass on your level turn and fill you full of holes with a snapshot.
Lots of other great concepts and information we could practice and use in ROF like Shotais, vertical/barrel roll weaves, placement/coordination of fighter sweeps/CAPs around targets, 2 on 2 engagement tactics to isolate 1 bogey and then concentrate on a second, etc.
2. The Zeppelin in Combat: A History of the German Naval Airship Division
http://www.amazon.com/The-Zeppelin-Comb ... at+history
Because zeppelins are cool and I still hold out hope that we're going to see them on the Channel Map as AI units as escort (German) and interception (British) objectives. Also interesting because this guy has done so much research on both sides that this book is arguably more accurate and definitive than the "official" records maintained by the British Imperial War Museum regarding the fate of certain airships during the war.
