When I was in Navy-Marine Corps MARS in the 1960s, I received an AN/SRR-13A, AN/ARR-15, AN/PRC-6, AN/PRC-34, and AN/PRC--36. For each I had to sign an equipment accountability form and be prepared to turn in the equipment when I left NAVMARCOR MARS. In the mid-1970s I received a letter that declared the equipment unsuitable for recovery and dropped accountability on everything. The original accountability forms that I had signed were returned to me.
I carried the AN/SRR-13A with me to several duty stations when I was in the USN. It was very useful while I was stationed in Idaho for naval reactor training. In 1975 SE Idaho, by midnight all local TV and broadcast stations were off the air. Shortwave was all there was.
I still have both the equipment and the forms. NAVMARCOR MARS is long gone.
Army and Air Force MARS of that era exercised no similar equipment accountability program.
