Most profiles are presented for the first time, alongside markings derivations, including squadron heraldry and codes. Frequent airframe reassignments between units resulted in wide-ranging and oft-changing unit markings and nose art. Until now there has been a paucity of material about several units, particularly those in the Thirteenth Air Force. This volume also rectifies past mistakes which continue to be perpetrated, especially those representing the early Australian theatre.

Wide ranging primary reference material is cited including official Australian assignment data, squadron records, colour slides and movies, maintenance logs, diaries, wreck site inspections and factory specifications. A brief history of each unit and the rationale of its unit markings accompanies the text.

The author is world-renowned for his expertise on the Pacific air war. Never before have USAAF Pacific P-40s and their colourful artwork been illustrated with such accuracy and detail.
