2. _Operations_, by which his plans are carried out. Each of these headings comprises an immense amount of detailed work, which cannot be here dwelt on further than to indicate its general scope. 1. _Intelligence_ means collecting information about the enemy and the theatre of war, from every possible source, and arranging for its transmission to Head-Quarters, to be examined and collated, and then laid before the Commander. This subject also includes everything connected with maps and topographical information, as well as Press Censorship, and provision of interpreters and guides. 2. _Operations_ include: (_a_) Working out details of dispositions and movements of troops, as to their _units_ and _numbers_, with especial attention to _place_ and _time_, and attention to the security of the troops in movement and at rest. (_b_) Embodying the Commander’s plans in clear and concise “Operation Orders.” (_c_) Transmitting these Orders with certainty and despatch. (_d_) Watching, and ensuring, their due execution. The services of _Inter-communication_ must be carried on under the control of the General Staff, so as to ensure the rapid transmission of Information to, and Orders from, Head-Quarters. But in addition to the above responsibilities which fall on the General Staff, there are also Staff duties involved in assisting the Commander to keep his Command in a state of efficiency, which depends on the following requirements: First, that its organization, discipline, health, and numbers be kept up. Secondly, that its material wants be met. These duties do not bear directly on the fighting, and so do not fall to the General Staff, but to the other branches. THE ADJUTANT-GENERAL’S BRANCH (A.G.) Duties under the first heading are undertaken by the Staff of the _Adjutant-General_, which deals with the following matters affecting the personnel of the Command: discipline, law, and police; pay, interior economy, and routine Orders; casualties and returns; appointments, promotions, and rewards; reinforcements, and organization of improvised units and local levies; the disposal of prisoners; collecting the wounded and burying the dead. All possible office work in connection with these matters should be done at the Base, so as not to burden the Troops in the Field with clerical work carried on under difficulties. Since the Adjutant-General’s Branch is responsible for the _health_ of the Force, the Medical Services are placed under its control in the British Service. In foreign armies they are administered by their own Heads at Head-Quarters of Divisions and Army Corps, under the control of the General Staff. THE QUARTER-MASTER-GENERAL’S BRANCH (Q.M.G.)
