This collection of squadron histories has been prepared by the USAF Historical Division to complement the Division's book, Air Force Combat Units of World War II. The 1,226 units covered by this volume are the combat (tactical) squadrons that were active between 7 December 1941 and 2 September 1945. Each squadron is traced from its beginning through 5 March 1963, the fiftieth anniversary of the organization of the 1st Aero (later Bombardment) Squadron, the first Army unit to be equipped with aircraft for tactical operations. For each squadron there is a statement of the official lineage and data on the unit's assignments, stations, aircraft and missiles, operations, service streamers, campaign participation, decorations, and emblem.

This paper clearly shows the immediate relevancy of historical study to current events. One of the most common criticisms of the U.S. plan to invade Iraq in 2003 is that too few troops were used. The argument often fails to satisfy anyone for there is no standard against which to judge. A figure of 20 troops per 1000 of the local population is often mentioned as the standard, but as McGrath shows, that figure was arrived at with some questionable assumptions. By analyzing seven military operations from the last 100 years, he arrives at an average number of military forces per 1000 of the population that have been employed in what would generally be considered successful military campaigns. He also points out a variety of important factors affecting those numbers-from geography to local forces employed to supplement soldiers on the battlefield, to the use of contractors-among others.
