Featuring over a thousand photos from the National Archives, diagrams, and detailed specifications, Hunnicutt's Half-Track remains the definitive development history of half-track vehicles for the military historian, professional soldier, and tank restorer. In this ambitious work, Hunnicutt details the developmental history of half-tracks, examining its modifications and effectiveness. Products of a pre-war development program, half-track vehicles served in all theaters of operation from the first to the final days of WWII, and many models remained active long after the Korean War. The armored half-track was one of few vehicles available to equip the new divisions being formed just prior to WWII. Part I traces the early development beginning with the slow half-track of WWI to the faster vehicles developed after the evaluation of the French Citroen-Kegresse P17 in 1931. These vehicles were unarmored half-track cars and trucks intended for use as prime movers and reconnaissance vehicles.In 1938, the half-track suspension was installed on the M2A1 scout car, and the converted vehicle became the half-track personnel carrier T7. This was the first armored half-track, but tests showed that it was underpowered. Based upon the experience with the T7, a new vehicle was designed in 1939 and designated as the half-track scout car T14. Using the half-track suspension from the T7 and a more powerful engine, it became the prototype for all of the half-tracks produced during WWII.In Part II, the development and production of half-tracks during WWII is described showing the many roles for which it was adapted. In addition to the original armored scout car, the basic chassis was adapted as a personnel carrier, mortar carrier, tank destroyer, self-propelled artillery, and other specialized applications. Some of these vehicles were temporary expedients, but others were so successful that they remained in use until long after WWII.Part III briefly describes some half-track operations during WWII and Korea. However, it is not intended to be an operational history, but to illustrate the effectiveness of the half-track in active service.
