APPENDIX

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.

MISSION AND FUNCTIONS

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--

--Providing tip-offs of current target activity.
--Providing updates to target methods of operation and technical data to support collection.
--Predicting target activity.
--Providing unit-specific tailored information.
--Evaluating the effectiveness of the overall process.

ORGANIZATION AND OPERATIONS

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:

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--

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--

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.
