Norm, that address to which you send for an IDPF is: US Total Army Personnel Command ATTN: TAPC-PAO (FOIA) 200 Stovall Street Alexandria, VA 22332-0404 Be sure to cite the Freedom of Information Act in your request.
(As others in this forum have addressed, the info found in an IDPF can be graphic. If you pursue this resource, be prepared for that possibility.)
