CAMP (from Lat. campus, field), a term used more par ticularly in a military sense, but also generally for a temporarily organized place of food and shelter in open country, as opposed to ordinary housing (see CAMPING-OUT). The shelter of troops in the field has always been of the greatest importance to their well-being, and from the earliest times tents and other temporary shelters have been employed as much as possible when it is not feasible or advisable to quarter the troops in barracks or in houses. The applied sense of the word "camp" as a military post of any kind comes from the practice which prevailed in the Roman army of fortifying every encampment. In modern war fare the word is used in two ways. In the wider sense, "camp" is opposed to "billets," "cantonments" or "quarters," in which the troops are scattered amongst the houses of towns or villages for food and shelter. In a purely military camp the soldiers live and sleep in an area of open ground allotted for their sole use. They are thus kept in a state of concentration and readiness for immediate action, and are under better disciplinary control than when in quarters, but they suffer more from the weather and from the want of comfort and warmth. In the restricted sense "camp" implies tents for all ranks, and is thus opposed to "bivouac," in which the only shelter is that afforded by impro vised screens, etc., or at most small tentes d'abri carried in sec tions by the men themselves. For training purposes in peace time, standing camps are formed. These may be considered simply as temporary barracks. An entrenched camp is an area of ground occupied by, or suitable for, the camps of large bodies of troops, and protected by fortifications.
