The M42 Duster was a tracked antiaircraft vehicle developed by Cadillac for the US Army in the early 1950s. The vehicle adapted the Bofors 40 mm AA gun to a modified M41T41 tank chassis. Although never particularly prolific in the intended air defense role, the Duster did find a niche during the Vietnam War. The M42 was relatively small and agile, and the high rate of fire and loud report from its guns were quite intimidating. These traits, along with simple availability, resulted in the type being pressed into ground combat against infantry and light vehicles, for which it received moderate acclaim. This volume includes over 300 photos of this quirky vehicle. Every nook and cranny of the interior and exterior is shown, along with many fascinating combat photos.
