Engineers and departmental units are divided into companies of varying strengths, according to the part they are called on to play when the division is constituted. Thus it is self-evident that an average division will require more Engineers, who do all the field work of construction and demolition, than it will Army Ordnance men, who attend to the equipment of the division--fitting out with clothing, provision of transport vehicles, etc. The number of men of departmental corps allotted to each division in the field varies with the strength of the division and with its distance from its base of supplies. There is a permanent and outstanding difference between the British Army as a whole and any Continental army as a whole. In the case of the Continental army--no matter which one is chosen for purposes of comparison, the conscript system renders it a part of the nation concerned, identifies the army with the nation, and incidentally takes out the element of freedom. A man in a conscript army is serving because he must, and, no matter how patriotic he may be, there are times when this is brought home to him very forcibly by the discipline without which no army could exist. In the British Army, on the other hand, the men serving are there by their own choice; this fact gives them a sense that the discipline, no matter how distasteful it may be, is a necessity to their training--by their enlistment they chose to undergo it. But the British Army, until the present war linked it on to the man in the street, was not a part of the nation, but a thing distinct from the nation; it was a profession apart, and none too enviable a profession, in the opinion of many, but something to be avoided by men in equivalent walks of civilian life.
