COMMAND, in military engineering, the height measured vertically of the crest of a fortified work above the natural sur face of the surrounding ground. In military organization it is used, in a general sense, to mean the whole number of troops under a particular officer's command, e.g., "General A's command," especially when comprised of fractions of different units or forma tions. In a specific sense it is applied in the British and Indian armies to the highest and largest nature of commands which exist in peace time. These are on a territorial basis, and in them are stationed a varying number of divisions and brigades. The troops at home are distributed among the Aldershot, Eastern, Northern, Scottish Southern and Western Commands, besides certain "dis tricts." The commands are usually sub-divided territorially into "areas." The army in India is divided territorially into the Northern, Western, Eastern and Southern Commands.
