William K. Emerson's Encyclopedia of United States Army Insignia and Uniforms is the first comprehensive, well-illustrated, fully researched, and completely documented history of U.S. Army branch insignia and the uniforms on which those insignia were worn. More than two thousand photographs illustrate the actual branch insignia used by men and women of the U.S. Army during war and peace from American independence to the present. This book tells the story of the major army branches - infantry, artillery, cavalry, and engineers - as well as the service and support branches comprising doctors and nurses, chaplains, musicians, quartermasters, military police, and the many others whom have made up the U.S. Army.
