If you still want the original, might be worth asking the Library of Congress Technical Reports and Standards Unit: https://www.loc.gov/rr/scitech/trs/trsover.html https://www.loc.gov/rr/scitech/trs/trsover.html I've had decent luck finding technical reports there. STANAG is not listed in their partial standards holdings, but that doesn't mean that they don't have anything from the organization.
