You must have read the "what is billeting?" article and are now wondering what a woobie is. A woobie is one of the military's greatest gifts to humanity. It is also called a Poncho Liner. (Please don't actually use it to line a poncho or you will just end up in a wet mess.) The woobie is a blanket that is highly regarded by veterans due to its comfort, warmth, light weight, and ability to fit in any bag. Just google "what is a woobie" if you would like more info regarding this American treasure.
