Officers' Field Bag, or Musette Bag. The officers' field bag is the container in which he carries personal items of equipment to provide for his necessities and comforts while on the march, away from the base camp or bivouac, and in the absence of his bedding roll. It is a necessary and convenient article. The officer will wish to have with him facilities with which to eat, a minimum of articles with which to wash and shave, some articles of clothing for replacement, and other small conveniences. On field service never let yourself become separated from your musette bag! The truck with bedding rolls may not come forward, or it may go astray; but if you have the essentials with you some of the discomforts are avoidable
