[Ed. note: In my earlier article, The Heraldry of Cryptology (Cryptologia 1984), I described the distinctive insignia of various U.S. Army units and branches with cryptologic related duties. These included several major units which had been merged in 1977 to form the United States Army Intelligence and Security Command (USAINSCOM). The article noted that included in the consolidation were a number of smaller intelligence agencies under the direct control of the Assistant Chief of Staff for Intelligence (ACSI) . We thank the INSCOM History Office for the following historical and heraldic information on one of those agencies; and for the delightful and informative essay on the sphinx which has been a principal heraldic symbol of U.S. military intelligence since 1923.
