Signals Intelligence Brigade

The Signals Intelligence (SIGINT) Brigade is a major subordinate command of INSCOM, and consists of a headquarters company, three battalions, a reserve augmentation detachment and an Individual Mobilization Augmentee (IMA) element. The Brigade conducts SIGINT operations in support of Army, ground component and joint warfighters, integrate reserve forces, and provides technically and tactically trained soldiers to support operations of the National Security Agency (NSA) and to execute operations to support land component commanders' information warfare and information operations.

The Signals Intelligence Brigade has three battalions and one Headquarters and Headquarters Company (HHC). The Brigade HHC's sole responsibility is to provide administration support to the Brigade Headquarters. The three battalions, Strategic Operations, Tactical Operations, and Space Operations Battalions, maintain headquarters operations primiarly at Fort George G. Meade, Maryland. In addition, the Tactical Operations Battalion has a detachment located in Draper, Utah while the Space Operations has the majority of its companies and detachments spread throughout the Continental United States as well as overseas locations.

The Brigade's structure is based on a division of expertise, governed both by mission and geography. Personnel assigned to the Strategic Operations Battalion are generally employed within the NSA's Operations Directorate. The Tactical Operations Battalion operates the Army Technical Control and Analysis Element (TCAE) and integrates soldiers to individual NSA support groups. The Space Operations Battalion is focused on world wide SIGINT operations.

SIGINT Brigade Mission

The mission of the SIGINT Brigade is to support the Warfighters' and National Decision- makers' information superiority requirements through the conduct of SIGINT, Information Security (INFOSEC), Information and Command and Control Warfare (IW and C2W), both directly and through support to the NSA.

The Mission Essential Tasks List (METL) of the SIGINT Brigade are:
  • Conduct SIGINT and INFOSEC Operations
  • Leverage National Systems to Support Warfighters
  • Provide trained toldiers to support NSA operations, as well as various global contingencies
  • Support Warfighters' and Policymakers' IW and C2W requirements
  • Integrate the Reserve Component (RC) in peacetime, stability and security operations, and wartime operations
  • Sustain and maintain the force
  • Strategic Operations Battalion

    The Strategic Operations Battalion provides direct support to the NSA's Deputy Director of Operations (DDO) in conducting SIGINT operations within NSA. The Battalion, in coordination with NSA and the National Cryptologic School, insures soldiers are technically proficient while insuring that soldiers are prepared for world- wide deployment. The Battalion serves as the Brigade's Executive Agent (EA) for daily operation of the Joint Language Center (JLC) and the Joint Learning Facility (JLF).

    Tactical Operations Battalion

    The Tactical Operations Battalion provides direct support to the Land Component Commander (LCC) in conducting SIGINT within its individual area of responsibility (AOR). This support is conducted through the Army TCAE located within NSA spaces. In addition, the Tactical Operations Battalion supports selected NSA operations and provides U. S. Title X oversight and support to the Utah National Guard (UTNG) SIGINT operations.

    Space Operations Battalion

    The Space Operations Battalion conducts nonconventional SIGINT operatons and leverages national systems in support of warfighters' and national decision- makers information superiority requirements. The battalion provides soldiers to Mission Ground Stations, to collection management sections in the National Security Agency and warfighter support sections to leverage national collection assets.

    ARMY Tactical Control and Analysis Element (TCAE)

    ARMY TCAE Mission

    The ARMY TCAE is assigned to the Headquarters and Operations Company of the Tactical Operations Battalion. The ARMY TCAE provides the bridge between the Army's Ground SIGINT operations, EAC and below, and the National SIGINT operations at NSA and the Regional SIGINT Operations Centers. The ARMY TCAE is located within the NSA complex at Ft. Meade, Maryland, however personnel are not are not assigned against NSA manning documents, and is the voice of the Army DCSINT on all SIGINT matters envolving Army Ground SIGINT elements.

    The ARMY TCAE have established both formal and informal relationships with both Army and National SIGINT operations. Formal working relationships have been established between NSA, the Regional TCAE's, and the CORPS MI Support Element (CMISE) and the ARMY TCAE. Informal relationships exists with the Regional SIGINT Operations Centers (RSOC), Mission Ground Stations (MGS), and SIGINT elements located at Echelions Corps and Below (ECB).

    The ARMY TCAE serves as the Army's link to integrated cryptology within joint military operations. As such, the ARMY TCAE is the expert within the National SIGINT Brigade in Land Operations. This requires the ARMY TCAE to retain a habitual relationship with G2's at all echelons and to maintain a flexible surge capability.

    Even though not an element of NSA, the ARMY TCAE is able to leverage NSA's capabilities on behalf of the Ground Component Commander's SIGINT elements. When Ground Component SIGINT units deploy during real- world operations, the ARMY TCAE obtains the newest technology, processing power, and target knowledge from the applicable NSA offices and provides it to the warfighter. Upon request, the ARMY TCAE will provide SIGINT Support Teams (SST's) designed to bring current and timely intelligence training directly to the warfighter's SIGINT element prior to deployment.

    The ARMY TCAE is responsible for the National/ Tactical integration at the NSA. ARMY TCAE personnel are integrated into key elements of NSA for the sole purpose of working Ground Component commander's requirements with a specified Office of Primary Interest (OPI's). The ARMY TCAE has also integrated into the operations at the various RSOCS, through the Regional TCAE, and has formed individual detachments at the individual Mission Ground Stations (MGS).
    The ARMY TCAE provides for a unique relationship between NSA and the Army. The ARMY TCAE is collocated or fully integrated within selected NSA production elements. These personnel are provided access to and works information that normally falls below the NSA production threshold, but is of interest to the warfighter. The ARMY TCAE provides the warfighter access to individual NSA databases by using existing NSA secure communications in a near- real time. The Army receives support through the ARMY TCAE by use of the TCAE/ ACE architecture as described in USSID 1600. The ARMY TCAE also provides direct support where no intermediate support exists as the situation dictates.

    ARMY TCAE Structure

  • The ARMY TCAE is divided into six sections. These sections are the Technical Analysis Activity (TAA), Current Operations, Operational Electronic Intelligence (OPELINT), and Support to Military Operations (SMO) I, II, and III.

  • Technical Analysis Activity (TAA)

  • The Technical Analysis Activity provides offensive Information Warfare (IW) technology development and conducts training, planning and execution of Information Warfare operations for the warfighter.

  • Current Operations

    The Current Operations section of the ARMY TCAE consists of six individual teams. These are the Military Operations Support Team (MOST), the Current Operations Support Team (COST), the ADP team, the Requirements Team, and the TROJAN Support Desk and ARMY TCAE Collection Operations Facility (ACOF). The Chief of the Current Operations, and Army O- 3, is located within the main office of the ARMY TCAE within the NSA complex. The individual teams are colocated within various NSA offices as well as in ARMY TCAE operational spaces.

    • Quality controls and enters TROJAN data transferred Klieglights into the NTSS
    • Coordinates ARMY TCAE actions with NSOC in support of units alerted for deployment
  • Current Operations Support Team (COST)

  • The Current Operations Support Team (COST) is located in the administrative spaces of the ARMY TCAE. The COST is responsible for the overall management of all Request For Information (RFI). This function includes tracking of all incoming RFI's, providing the individual request to the proper office within the ARMY TCAE, and provides the formal response to the RFI originator. The COST maintains a close relationship with the NSA Field Support Office and the National Cryptologic School to provide timely support to the tactical Army in the forms of native language periodicals to current course listings.

  • Requirements Team

  • The ARMY TCAE Requirements Team is colocated within the NSA office responsible for Intercept Tasking Data Bases (ITDB) and United States Signal Intelligence Directives (USSID). The Requirements Team is responsible to manage and maintain all of the tactical Armys ITDB's to insure that they are current and reflect the individual units SIGINT missions. In addition, the Requirements Team acts as the laison between the tactical SIGINT unit and NSA to insure that all of the units USSID holdings are current and meet the needs based on the individual ITDB. The Requirements Team also assists tactical Marine SIGINT units on both ITDB and USSID issues.

  • TROJAN Support Team

  • INSCOM HQ has tasked the ARMY TCAE TROJAN Support Team to provide a 24 Hour help desk for all TROJAN Classic and Spirit issues. The TROJAN Support Team acts as the honest broker to insure maximum ulitization of TROJAN Classic collection systems across the Army. To complete this, the TROJAN Support Team works directly with Fort Belvoir TROJAN Switch, FORSCOM, and USAEUR on all TROJAN management functions. The TROJAN Support Team provides the means to track all TROJAN systems and SPIRIT's worldwide. The TROJAN Support Team manages the ASAS- SS, JDISS, and TROJAN communications for the ARMY TCAE.

  • ARMY TCAE Collection Operations Facility (ACOF)

  • The ARMY TCAE Collection Operations Facility (ACOF) is a fully operational TROJAN Classic activity. In addition, the ACOF serves as one test bed for the ENHANCED TROJAN operations system. The mission of the ACOF is to serve as a center for target development center for tactical SIGINT organizations

  • The OPELINT Team is completely intergrated in NSA operations to provide for access to the National Databases by tactical SIGINT units as well as providing tactical expertise to the National mission.

  • Support to Military Operations (SMO)

  • Support to Military Operations (SMO) is divided into three sections and is designed to mirror the Regional SIGINT Operations Centers. The SMO- I mission follows that of the Median RSOC, SMO- II that of the Gordon RSOC, and SMO- III the Kunia RSOC. The ARMY TCAE has integrated soldiers into various Office of Primary Interest's (OPI's) to insure that the interest of the Land commander is understood and requirements are answered. In addition, by placing individual soldiers within these various OPI's, tactical Army SIGINT gains access to the most current National SIGINT databases.

  • ARMY TCAE Communications Structure

  • The ARMY TCAE maintains several means of communications that are monitored on a hour a day basis. These systems run the gamut from secure (STU- III) and non- secure telephone to ASAS to formal electronic traffic. Communications with the ARMY TCAE can be made by using any one of the following:
