In the Canadian Forces this is normally referred to as a ground sheet, but is also called a half shelter. It is issued with no poles, pegs, or strings, and generally paracord is used to secure it to trees and other surroundings. 

These are all in good shape with any holes and /or tears repaired properly where needed

One half shelter is great for a waterproof lean to shelter. With two half shelters you can zip them together to make a tent.

great survival item
