The Royal Green Jackets are widely acknowledged as innovators who developed much of the thinking of the British infantry in the fields of tactics and training, mobility and marksmanship, equipment, management and individual initiative from the 18th century onwards. They were the first to wear green uniforms as camouflage rather than red and to fire the more accurate rifle instead of muskets. This book examines the history of the component regiments of the Royal Green Jackets and describes the action of individual regiments in the Napoleonic Wars, Boer War, and World Wars.
