Hi Icemaster — Warpath Across the Pacific IS awesome and worth every penny. The number of high-quality photos from strafing runs is staggering—we're talking about being able to see Japanese sailors bobbing in the water next to their belly-up ship and soldiers hunkering down in their AA pits. It also contains tons of great nose-art photos and is a superbly researched book.
As far as A-20s go, the same publisher offers Rampage of the Roarin' 20s, a book about the 312th BG. It is virtually identical in format to the previously mentioned book and again, well worth the money.
If you want to go into extreme technical detail about the B-25, check out B-25 Mitchell The Ultimate Look by William Wolf. He literally covers everything from rivets and fasteners to oil and fuel pumps, rescue equipment, radios, armament, and on and on.
Osprey Publishing is scheduled to release A-26 Invader Units of WW2 this October.
