Maybe the military could improve the print quality to help making OCR postprocessing more accurate. It could be as simple as using a better font on higher quality paper printed by a better printer. It would also help if all spaces were printed twice to make word separation better. Also an end-of-line sign could be printed followed by a CRC code.

Maybe the military could accept comparing your OCR generated electronic copy with the original file in a computer at their location. They would then issue a paper printout stating the file identification followed by REJECTED or ACCEPTED.
