Shelter-half

Military field equipment

A shelter-half is a simple kind of partial tent designed to provide temporary shelter and concealment when combined with one or more sections. Two sheets of canvas or a similar material are fastened together with snaps, straps or buttons to form a larger surface. The shelter-half is then erected using poles, ropes, pegs, and whatever tools are on hand, forming an inverted V structure. Small tents like these are often called pup tents in American English.
