Facility of Subdivision
The British organization is so planned that the Force can be readily divided, when required, into two Armies, each of which can be provided with its proportion of Strategic and Protective Cavalry, and of Army Troops, without disorganizing and rearranging those Formations.
This principle has been carried throughout the Force. Thus, the Cavalry Division can supply any detached Brigade with the Divisional Troops required—namely, a Battery of Horse Artillery, a Field Troop of Engineers, a Section of the Wireless Telegraph Company, a Field Ambulance, and a Company of A.S.C. to form the Brigade T. and S. Column, there being one of each of these Divisional Units for each Brigade to be detached.
Similarly, the Cavalry Brigade can detach one of its Regiments provided with Sections from the Field Troop of Engineers, the Field Ambulance, and the A.S.C. Company, so as to be self-contained.
In exactly the same manner, the Division of Infantry can at any time detach a Brigade provided with its due proportion of all Arms and Administrative Services, without confusion and delay.
The Infantry Brigade, also, can detach Battalions equally self-contained; and the Artillery Brigade can allot a Section of its Ammunition Column to any Battery which it may be desirable to detach.
