That will retrieve all documents that start with that code. Look for the Active volumes, currently 1F, 2F, 3F, 4A, and 5. MIL-17 is a full specification reference in PDF format, from the U.S. Army. See also http://www.mil17.org/ for further information about the specifications and data. WSU also has a paper copy in our collection. http://assist.daps.dla.mil/
