ARMY TECHNICAL CONTROL AND ANALYSIS ELEMENT

The Army TCAE provides support and guidance to Army tactical SIGINT units. The Army TCAE is the highest echelon in the Army's technical control architecture and serves as the single. POC at NSA for Army theater and tactical forces. This technical architecture extends through TCAEs located at theater or MACOM to corps and down through division, ACR, and separate brigade TCAEs. Figure A-1 shows this structure.

The Army TCAE is collocated with NSA. It performs quality control of reported intelligence information and technical data exchange under the technical supervision of target area offices within NSA. Technical data and technical taskings from the Army TCAE to EAC and ECB units are sent in the form of SIGINT technical messages. Other messages provide guidance to tactical units in the form of SIGINT operations policy, directives, and doctrine.

The mission of the Army TCAE is to provide SIGINT technical support to the Army's theater and tactical forces in peace and war. The Army TCAE is divided into operational teams and sections to provide tailored support to each EAC or ECB SIGINT unit, based on specific operational and training needs. The Army TCAE provides DS to TCAEs and ECB units that do not have a theater EAC TCAE. The Army TCAE--

• Serves as the single POC between NSA and the Army's EAC and ECB forces for providing technical information to support SIGINT operations.
• Monitors intercept tasking data base (ITDB) submissions to ensure that the commander's PIR and IR have been clearly stated.
• Provides quality control feedback on SIGINT reporting, ITDBs, and CM matters in support of the EAC TCAEs and other tactical SIGINT units not supported by an EAC TCAE.
• Acts as the TROJAN system manager, network manager, and network security manager. (TROJAN is a program to facilitate SIGINT operations.)
• Operates the TROJAN system control desk which oversees the TROJAN switching network and the allocation of system resources to the field.
• Services requests for technical information to support EAC and ECB SIGINT operations by providing tailored data extracted from resident NSA data bases, working aids, and training aids.
• Assists SIGINT units in developing collection, processing, analysis, and reporting philosophies and techniques.
• Participates on selected NSA field assistance visits for Army SIGINT units. Coordinates for the unit concerned to resolve technical issues addressed during such visits.
• Under the provisions of AR 350-3, assists in providing general analytic and language training and any location-specific training necessary to enhance signals collection, processing, analysis, and reporting techniques at the tactical level. This can be accomplished to meet the requirements of a deploying unit or to upgrade soldier skills during peacetime operations.
• Identifies and provides information on potential collection opportunities for SIGINT units conducting training or operational missions. This five-step process entails---

The Army TCAE, shown at Figure A-2, is organized to provide SIGINT technical support to Army theater and tactical forces in peace and war.

OPERATIONS ELEMENT

The operations element is divided into four support teams and a TROJAN section in which the operations officer directs and supervises operations in each team and section. The operations element maintains status on RIIs and tracks them to ensure timely support is provided to Army SIGINT organizations in every OCONUS, theater, CONUS, and SIGINT unit which might be deployed to support contingency operations.

Support Teams

Team A supports all SIGINT units in the European Theater and United States Army Forces Command (FORSCOM) with European contingency missions. Team B supports all SIGINT units on the Korean Peninsula and FORSCOM units with a Korean, Pacific, or Northeast Asia mission. Team G supports primarily USSOUTHCOM, United States Central Command (CENTCOM), and FORSCOM SIGINT units with a mission in Central or South America and Southwest Asia. Team W supports all SIGINT units for their ELINT requirements.

To facilitate providing technical support to the Army's SIGINT units, theater and MACOM TCAEs have been designated as follows:

• Army Europe TCAE (AE-TCAE), which supports United States Army, Europe (USAREUR).
• Army Forces TCAE (AF-TCAE), which supports FORSCOM.
• Army Korea TCAE (AK-TCAE), which supports Eighth United States Army (EUSA).
• Army South TCAE (AS-TCAE), which supports USSOUTHCOM.
• Southwest Asia TCAE (SWA-TCAE), which supports CENTCOM.

TROJAN Section

The TROJAN section publishes periodic TROJAN-related reports and supervises the operations of the TROJAN system control desk. Exercising OPCON of the worldwide TROJAN switching network, the TROJAN system control desk--

• Monitors system status.
• Acts as the POC for allocating and switching resources to ensure adequate sharing between MACOM and theater TCAEs (based on mission needs).
• Assists units in obtaining the required maintenance support for TROJAN operations as needed.

This last function is performed 24 hours per day, 7 days per week. The Army TCAE is the TROJAN system manager, network manager, and network security manager. At the theater and MACOM levels, TROJAN system management will be exercised by the designated theater and MACOM TCAEs. In accomplishing this task, these TCAEs--

• Maintain system operational readiness data.
• Assess system operations.
• Implement troubleshooting procedures when required.
• Assist in implementation and system restoration.
• Initiate or recommend necessary changes in operating and maintenance procedures or logistic support.

PLANS ELEMENT

The plans element is responsible for long-term planning and direction for the Army TCAE. This is done through an internal plan which brings together Army doctrine, the Army Intelligence Master Plan, and TCAE operations. The plans officer also supervises the ADP section, US Signal Intelligence Directive (USSID) section, and ITDB section.

Automatic Data Processing Section

The ADP section plans and supports Army TCAE ADP internal needs. External support to Army SIGINT organizations is focused on developing specialized programs and standardized applications to maximize the existing ADP technology currently fielded. To further enhance the depth of technical support to Army SIGINT organizations, the ADP section works closely with NSA to gain data base access for the Army TCAE through the use of local area networks.

US Signal Intelligence Directive Section

The USSID section establishes, issues, and ensures accuracy of all USSID accounts held by Army SIGINT organizations. This section validates recommended changes to existing directives. It coordinates extensively with INSCOM and DA on all matters pertaining to Army policy and guidance related to USSID which may affect Army SIGINT units.

Intercept Tasking Data Base Section

The ITDB section monitors the input of the tactical commander's PIR and IR by subordinate TCAEs for compliance with existing USSIDs . It tracks SIGINT resources held in the field and ensures that the technical reports reflect the technical information needs of the organization.
