Is this file copyrighted?
Can someone help me clarify whether this file violates copyright? The document was released by | Foreign Technology Division, who also translated the original work. On the first page, it says ''Distribution of this document is unlimited. It may be released to the Clearinghouse, Department of Commerce, for sale to the general public.''. I got the file from the | Defense Technical Information Center website. Sunlitsky 15:04, 29 March 2024 (UTC)
