A GUIDE TO STUDYING HISTORY AT FORT HUACHUCAfilled the void. This involvementwith civilian intelligence brought criticismand recriminations for the <strong>Army</strong>which ended its domestic collectionin 1970. The Defense InvestigativeService came into being to performthe background investigations necessaryto grant security clearances, a jobthat had made up 90 percent <strong>of</strong>USAINTC’s mission. Significantlycut back in mission and personnel,USAINTC was closed down in 1974.It was replaced by the U.S. <strong>Army</strong> IntelligenceAgency (USAINTA), a fieldoperating agency <strong>of</strong> ACSI.The U.S. <strong>Army</strong> Security Agency(USASA) became a major army fieldcommand in 1964 and then becameknown as the U.S. <strong>Army</strong> Intelligenceand Security Command (INSCOM)in 1977.<strong>Army</strong> Chief <strong>of</strong> Staff Harold K.Johnson approved on 1 July 1967 therecommendations <strong>of</strong> the NorrisBoard, a body specially created to lookat the <strong>Army</strong>’s intelligence programsand organization. As a result, the old<strong>Army</strong> Intelligence and SecurityBranch, which had included the <strong>Army</strong>Security Agency (ASA), now becamethe Military Intelligence Branch. The<strong>MI</strong> mission changed from one <strong>of</strong>combat service support to combatsupport. And now the <strong>Army</strong> beganstudying the possibility <strong>of</strong> moving theIntelligence School from <strong>Fort</strong>Holabird and centralizing the trainingfor the many intelligence specialties.The early years <strong>of</strong> the war foundmilitary intelligence assets inadequateand unsophisticated, a situation whichhad become the pattern in everyAmerican war. In 1965 there were200 U.S. army <strong>of</strong>ficers serving as intelligenceadvisers with Republic <strong>of</strong>Vietnam troops. When U.S. combattroops were committed in thatyear, the 704th Intelligence CorpsDetachment, a detachment <strong>of</strong> the500th Intelligence Corps Group, andthe 3d Radio Research Unit were onduty in Vietnam. But there wereshortages <strong>of</strong> specialists, especially linguists.Lieut. Gen. Harry W. O.Kinnard, commanding the 1st CavalryDivision in 1965, commented onthe early problems with identifyingthe enemy:When I took the 1st CavalryDivision to Vietnam in 1965, I knewthat finding the enemy would be one<strong>of</strong> our toughest jobs. It occurred tome that perhaps we would be able toidentify the guerrilla, a farmer by dayand a fighter by night, by the darkcircles under his eyes.... As it turnedout, our surveillance was just aboutthat unsophisticated.But improvements were on theway. By the 1968 Tet Offensive,there were 2,500 intelligence specialistsin country under the supervision<strong>of</strong> the U.S. Military Assistance Command,Vietnam (MACV), J-2. InSaigon the 525th Military IntelligenceGroup exercised command and controlover the 135th <strong>MI</strong> Group, acounterintelligence unit; the 149th<strong>MI</strong> Group, which engaged in positivecollection; the 1st <strong>MI</strong> Battalion(Aerial Reconnaissance); and the519th <strong>MI</strong> Battalion, which operatedthe joint US/RVN intelligence centers.The combined intelligence centersshared jointly gathered intelligence,translated captured documentsand interrogated prisoners. There wasa center at MACV and at each <strong>of</strong> thefour corps areas in which the Republic<strong>of</strong> Vietnam <strong>Army</strong> (ARVN) operated.There were over 600 intelligenceadvisers on the ground nowwith the RVN <strong>Army</strong>. The 509thRadio Research Group ran a field stationand provided support through itstactical units to units down to brigadelevel. Combat troops had their ownorganic intelligence assets.Another unique type <strong>of</strong> unit to beintroduced in the Vietnam War wasthe Long-Range Reconnaissance Patrol(LRRP) which consisted <strong>of</strong> fourto six-man teams inserted into enemyterritory to gather intelligence or submitbattle-damage assessments. TheMilitary Assistance Command, Vietnam,Studies and Observation Group(MACV-SOG) was a joint serviceunit under the command <strong>of</strong> the Commander-in-Chief,Pacific(CINCPAC), which inserted intelligenceteams into enemy territory byland, sea or air.It was during the Vietnam Warthat military intelligence reached apotential unparalleled in history. Usingthe latest electronic gear to detectthe enemy, both from the air and theground, hostile concentrations werepin-pointed and enemy traps wereavoided or surprised. Ground surveillanceradars were employed, sidelookingairborne radar (SLAR) wasdeployed and a variety <strong>of</strong> night observationdevices were used whichtook advantage <strong>of</strong> infrared and image-intensification.The first use <strong>of</strong> UnattendedGround Sensors (UGS) was made bythe Marines at Khe Sanh in 1968.They were credited with contributingto the successful defense <strong>of</strong> theMarine base and would evolve in bothsophistication and numbers deployed.The UGS could detect the presence<strong>of</strong> the enemy by acoustic, seismic, ormagnetic indicators which were sentback to monitoring stations.38Call (520) 533-3638, DSN 821-3638, FAX (520) 533-5736.
A BRIEF HISTORY OF U.S. ARMY <strong>MI</strong>LITARY INTELLIGENCEThe combat intelligence battalionthat was assigned to a division duringthe Vietnam War was organized asfollows: A headquarters and headquarterscompany was responsible forcommand and control, communications,radar, remote sensor and vehiclemaintenance, and supply services.Ground surveillance radars and remotesensors were deployed by a materielexploitation platoon <strong>of</strong> theHHC. An intelligence operationscompany furnished counterintelligenceand interrogation support forthe division and manned the battlefieldinformation control centers(BICC) and battlefield informationcenters (BIC). Long-range reconnaissancefor the division was providedby the ground recon-naissance and surveil-lancecompany. An aerial targetacquisition and combat surveillancecompany had the job <strong>of</strong> providingboth aerial electronic surveillance andimagery inter-pretation through theuse <strong>of</strong> utility and attack helicopters.Some concepts growing out <strong>of</strong> theVietnam experience were the Surveillance,Target Acquisition, Night Observation(STANO) program, an intensivemanagement system for surveillanceoperations and products; andthe Integrated Battlefield ControlSystem (IBCS), a program designedto aid the commander’s decisionmakingprocess by combining all <strong>of</strong>the technological tools.Perhaps the single greatest reasonfor the improved intelligence apparatusin the Vietnam War was the sense<strong>of</strong> pr<strong>of</strong>essionalism instilled by an <strong>MI</strong>branch. During the war in Vietnam,the Military Intelligence Branch grewto 7,000 <strong>of</strong>ficers and became the fifthlargest branch. Colonel William F.Strobridge, the G2 in the 4th InfantryDivision operating along the Cambodianborder in 1970, expressed hisfeelings on being in the Military IntelligenceBranch, created only threeyears earlier:...possibly unlike the non-<strong>MI</strong>Branch <strong>of</strong>ficer, I felt as an <strong>MI</strong> <strong>of</strong>ficerworking as a combat division G2 thatI was at the zenith <strong>of</strong> my pr<strong>of</strong>essionaland personal satisfaction. I was playingfirst fiddle for a varied and skilledassemblage <strong>of</strong> intelligence players thatwere part <strong>of</strong> my chosen career field. Ifelt, as an <strong>MI</strong> <strong>of</strong>ficer, I had greatercommand <strong>of</strong> the multiple types <strong>of</strong>intelligence support I could get for thedivision. As an <strong>MI</strong> <strong>of</strong>ficer, I couldtalk nose-to-nose with other <strong>MI</strong>people on the quality and timeliness<strong>of</strong> their support, and as an <strong>MI</strong> <strong>of</strong>ficerI could eradicate any hangups <strong>MI</strong> personnelmight have about supportingan infantry division. There is no questionin my mind that the <strong>MI</strong> specialists,sergeants, warrant <strong>of</strong>ficers, lieutenants,captains, and majors that Iworked with each day passed the testin the 4th Infantry Division, becausewhen the division commander receiveda richly deserved promotion,he specified he wanted another <strong>MI</strong><strong>of</strong>ficer for his G2.Despite all <strong>of</strong> the acknowledgedsuccess <strong>of</strong> intelligence support in Vietnam,there were still deficiencies, most<strong>of</strong> which could be categorized under“untimely response.” It was GeneralPatton who remarked that he likedintelligence, “like eggs, the fresher thebetter.” The appetite for intelligenceis and always will be insatiable. Theresult is <strong>of</strong>ten an information overloadthat strains the ability <strong>of</strong> the systemto process and disseminate theanalyzed information in a timely manner.In Vietnam, depending on thesource, the time elapsed from the occurrence<strong>of</strong> an event to the time thereport reached the hands <strong>of</strong> the usercould range from 15 minutes in thecase <strong>of</strong> a triggered ground surveillanceradar to 72 hours in the case <strong>of</strong> anagent report. In between were elapsedtimes <strong>of</strong> 20 minutes for an airbornepersonnel detector, 50 minutes for anunattended ground sensor, an hourand a half for a usually reliable intelligencereport, known as “special intelligence,”four hours for SLAR and airborneinfrared, five and one-half hoursfor prisoner interrogation, and sixhours for intelligence civic action program.These processing times weretoo long to be useful to the commanderwho was dealing with a fastmoving,guerilla force which dependeda great deal on deception.After Vietnam, the U.S. <strong>Army</strong>was determined to find a better wayto organize and focus its intelligenceassets to more efficiently serve thecombat commander.In the final years <strong>of</strong> the VietnamWar, and over the decades that followed,<strong>Army</strong> intelligence faced athicket <strong>of</strong> challenges and alternatingbouts <strong>of</strong> contraction and growth. Thelast quarter <strong>of</strong> the 20th century wouldbe a time <strong>of</strong> self-definition and reemergenceas an equal partner withoperations, personnel, and logistics.With the war in Southeast Asiaover, the emphasis pivoted to theEuropean theater where intelligencewas expected to counter the superiornumbers <strong>of</strong> the Warsaw Pact forceswith the celerity <strong>of</strong> its early warninginformation.The <strong>MI</strong> community would betransformed, not only by its ownfrenzy <strong>of</strong> reorganization, but bychanges taking place in the U.S. <strong>Army</strong>as a whole.
