An interesting thing happened at the Department of Veterans Affairs (VA) in July (2013), to little fanfare and even less media coverage; the VA approved the addition of the "Hammer of Thor" to their list of symbols allowed to be placed on the tombstones at the grave sites of veterans who are buried in veteran cemeteries. The newly approved symbol is intended for the practitioners of a form of paganism that worships the Norse pantheon, including Thor.
