This United States Army Medal is 1″ in diameter and is made of Sterling Silver. On the back of the medal is Saint Michael the Archangel, who is the general of God’s army and the great protector from evil. It has a 24″ stainless steel chain and is gift boxed. Members of our military are in great need of protection, and there is no greater protection from the evil one than that of St. Michael. This is a beautiful medal!
