The Signal Corps : the emergency (to December 1941)
This volume traces the course which the Signal Corps followed between the first and second world wars, a period of planning and preparation. The reader can here follow from birth the history of Army radar and mobile radio, the first steps taken in the conversion of the civilian communications industry to war production, the expansion of training facilities, and the beginnings of the far-flung communications network that eventually encircled the globe. -- From the Foreword
