SOME MILITARY TERMS. Before we proceed, we must clearly understand some terms which are used in war. In reading newspapers we frequently meet with the term army corps. A modern army is made up of a certain number of _army corps_, each of which is a complete army in itself. At the beginning of a campaign we may reckon an army corps to consist roughly of 40,000 men of all arms, under the command of a general. An army corps is divided as a rule into two _divisions_, and each division is also a complete little army in itself. Study this little table, and you will see the composition of a British division. Total Officers No. of No. of Guns, No. of Vehicles, and Men. Horses. including including Machine those of Guns. the Artillery. 1 Headquarters 82 54 -- 7 3 Infantry Brigades 12,165 741 24 309 1 Headquarters Divisional Artillery 22 20 -- 2 3 Field Artillery Brigades 2,385 2,244 54 240 1 Field Artillery (Howitzer) Brigade 755 697 18 67 1 Heavy Battery and Ammunition Column 198 144 4 19 1 Divisional Ammunition Column 568 709 -- 110 1 Headquarters Divisional Engineers 13 8 -- 3 2 Field Companies of Engineers 434 152 -- 102 1 Signal Company 162 80 -- 53 1 Cavalry Squadron 159 167 -- 9 1 Divisional Train 428 378 -- 176 3 Field Ambulances 702 198 -- 72 18,073 5,592 100 1,169 Such a division on the march would cover from head to tail about 15¾ miles. The supreme head of all the army corps which form an army is a commander-in-chief, or generalissimo, who is assisted by what is called the supreme general staff. The commander-in-chief and his staff are the brain and driving force of the army as a whole. It will interest you to learn how the commander-in-chief and his staff are linked up with every part of the army.
