“ Military or naval property may move for civil use, as where army or navy surplus supplies are shipped for sale to the public. But in general the use to which the property is to be put is the controlling test of its military or naval character. Pencils as well as rifles may be military property. Indeed, the nature of modern war, its multifarious aspects, the requirements of the men and women who constitute the armed forces and their adjuncts, give military or naval property such a broad sweep as to include almost any type of property. ”
