Note 24 — Chapter VI · FIRE DIRECTION AND CONTROL

All subordinate commanders are responsible for keeping their respective superiors, as well as neighbouring commanders, regularly informed of the progress of events, and of important changes in the situation as they occur. All ranks should notice what takes place within their view and hearing, and report anything of importance accurately and at once to their immediate superior, who must pass the information on to the higher commanders and to neighbouring units. This is the foundation of co-operation in war, and is essential not only in battle, but at every stage of a campaign.—Infantry Training, 1914.
