I saw a television show on the Discovery channel that shows Marines going through basic training. One of the scenes showed the soldiers using a cloth, a little smaller than a towel, with the major components of the M-16 in an outline form layed out with their names. I assume they use this as a training tool to allow the soldiers to easily learn the component names and the assembly procedure of the weapon.

Does anyone know if these or a similar product is available on the civilian market?
