The Army National Guard provides the American Hero Band free to those that wish to show their support for the members of the Army National Guard.
The words "IN HONOR OF AN AMERICAN HERO, SERVING IN THE ARMY NATIONAL GUARD" are engraved on the metallic wristband. There is an Army National Guard logo on the left and an American Flag on the right. It has a unique serial number engraved inside wristband.
When you receive your band you can register it. If you pass your band on to someone else they can reregister it and that way journey of the band from person to person can be traced across the country.
At this writing you can only order one band, but they are considering allowing people to request two -- one to keep and one to give away.
