This study of the evolving uniforms and personal equipment used by US ground forces in the Korean War features new full-color artwork and previously unpublished photographs. In June 1950, US soldiers and Marines deployed in the Korean War were dressed and equipped largely as they had been in the closing stages of World War II, but by 1953 major innovations had transformed their appearance. Featuring eight pages of specially commissioned artwork alongside carefully chosen photographs, some never previously published, this study charts the evolution of the US troops’ uniforms and gear through three years of bitter fighting. The deployment of a US expeditionary force in Korea entailed uniform and equipment shortages and resulted in widespread improvisation among the troops. The rapid movement of the first stages of the conflict made resupply very difficult, a situation compounded by the need for cold-weather clothing. In 1951, the beginnings of position warfare offered the opportunity for soldiers and Marines to customize their uniforms and gear. Flak jackets were introduced in both services. The infantryman’s basic load lightened substantially, with men on the line often requiring little more than their fatigues, flak vest, and helmet. All of these developments are explained and depicted in this fully illustrated study from an authority of the uniforms and personal gear of the Korean War period.
