This 1917 manual of musketry training is designed to instruct all infantry ranks in the use and care of their rifles, even under the gruelling battle conditions of the western front in the fourth year of the Great War. It is also aimed at instructing Commanding officers to make the best use of their men's firepower under all conditions. There are chapters on the care and maintenance of arms; on visual training and distance judging; fire discipline and range firing; and section, platoon and company training.
