4-73. Tactical brigades and battalions extend information network services to the deployed Army HQ and other deployed subordinate organizations allocated to the Army’s AO. Tactical units are not organic to a signal command, but are allocated based on mission requirements. Network assets are apportioned to supported units according to METT-TC and the supported unit’s specific communications and network requirements.

4-74. The mission of the theater tactical signal brigade (TTSB) is to C2 up to five tactical battalions and any other assigned or attached forces necessary to meet the network support missions in the theater of operations. The TTSB is equipped, manned, and organized to provide C2 functions and staff assistance to the subordinate units, staff supervision, personnel actions and administration, and logistics actions. TTSBs are forces assigned to NETCOM and OPCON to specific supported CCDRs, service component commanders, or JTF commanders. TTSB contains the normal headquarters and staff elements found in other tactical formations (Figure 4-5). The TTSB—

z Conducts systems planning, transport, and infrastructure

engineering.

z Develops architecture, design, and integration studies. z Determines technical circuit characteristics.

z Develops plans for establishing communications systems.

z Provides field support and sustainment support to operational missions in the form of ESBs.

z Can provide a span of control for echelons above corps (EAC) signal support to JOA.

z Provides passive and value-added services to Army Forces within the JOA, including common user services and continuity of operations facilities.

4-75. The S-1 is responsible for all human resources and administrative functions in the brigade, to include advising the commander on all human resource related issues and providing legal advice and assistance, supported by personnel of the Judge Advocate General Corps.

4-76. The logistics staff officer (S-4) provides oversight for all and logistics plans and functions for the brigade. This section also advises the brigade commander on all matters pertaining to logistics, transportation, deployment, and maintenance.

4-77. The communications operations section for the brigade (S-3) conducts detailed systems integration and network planning functions for the brigade. This section is also responsible for—

z Determining equipment suitability and adaptability with existing

communications systems.

z Handling frequency requests and associated records for the brigade units.

z Establishing the brigade communications systems control element (CSCE) responsible for keeping network situational understanding and status of current and future needs for rerouting or reconstituting circuits and facilities throughout the communications system.

z Providing effective operational management and responsive

systems control.

z Taking appropriate actions to optimize the deployed network

performance in response to constantly changing network configurations.

z Establishing and maintaining required databases necessary to assist

in near real-time control of communications systems and to assist the signal plans and intelligence section in systems planning and engineering.

Note. The majority of the following signal brigades will

become a theater’s senior signal organization to perform more effectively and efficiently the Service Title 10 functions that support the transformed campaign–quality operating force with joint and expeditionary capabilities.

1st _{Signal Brigade}

4-78. This brigade provides OPCON support to United States Forces, Korea (USFK) and 8th _{US Army in the Korean theater of operations.}

The 1st _{Signal Brigade commander serves a dual role as the 8}th _Army

G-6 with an augmenting staff provided by the 311th _{SC(T). The 1}st

Signal Brigade is unique in that it has both tactical and strategic battalions assigned which provide a combat-ready, forward-deployed LWN capability for responsive theater tactical, strategic, and installation signal support to CCDRs, the United Nations Command, Combined Forces Command, USFK, and warfighters in the 8th Army

area across the spectrum of operations. During wartime, the 1st _Signal

Brigade comes under the OPCON of the 311th _{SC(T) for the}

USPACOM or 8th _{Army AO.} 7th Signal Brigade

4-79. This brigade provides OPCON support to USAREUR. It maintains a combat-ready, forward-deployed signal force to deploy, install, operate, and maintain seamless theater tactical information system support to US and NATO warfighters in the USAREUR/USEUCOM AOR.

11th _{Signal Brigade}

4-80. This brigade is a CONUS based unit that is regionally focused to provide theater level and special tactical requirements to support USCENTCOM, USARCENT, and USPACOM, as required. The 11th

Signal Brigade also provides support to worldwide contingencies in response to the joint staff, HQDA, and NETCOM mission directives to install, operate, maintain, and restore LWN systems across any spectrum of conflict to include support to the BCT level, as necessary. The 11th _{Signal Brigade provides a forward stationing}

presence using the 54th _{Signal Battalion in order to meet daily signal}

and DOIM support in the USCENTCOM AOR.

35th Signal Brigade

4-81. This brigade is a CONUS based unit that is regionally focused to provide theater level and special tactical requirements to support United States Army South (USARSO). The 35th _{Signal Brigade}

commander serves a dual role as the USARSO/G-6. The 35th _Signal

Brigade can also support worldwide contingencies in response to the joint staff, HQDA, and NETCOM directives to install, operate, and restore theater tactical communications across the spectrum of conflict.

228th _{Signal Brigade and the 261}st _{Signal Brigade}

4-82. These brigades are ARNG tactical brigades under the command of the ARNG during peacetime. Their mission focus is homeland defense and CONUS contingency requirements. In wartime, the units are under the command of NETCOM and are assigned IAW applicable operation plans.

359th _{Signal Brigade}

4-83. This brigade is an USAR TTSB under the command of the USARC and the 335th _{SC(T). In wartime, the unit is commanded by}

NETCOM and is assigned IAW applicable operation plans.

4-84. The theater signal maintenance company (TSMC) is a one of kind unit that, with its current structure, supports the TTSB as an initial-entry deployer, providing immediate readiness of all ground support equipment to facilitate the critical theater signal mission. It also provides rapid deployable and dedicated general support and limited depot signal support for a theater of operations for the TTSB. 4-85. The 556th _{TSMC is assigned to the 11}th _{Signal Brigade and the}

current structure includes a HQ platoon and three maintenance platoons. When deployed, the TSMC supports MCO by using a dedicated platoon as required (usually one platoon per MCO) to support TTSBs.

4-86. The TSMC’s mission is to provide dedicated sustainment maintenance and class IX supply support to a theater of operations for TRI-TAC, MSE, computers, and conventional CE end items and components.

4-87. The TSMC provides a maintenance control section for theater unique and common signal assemblages. It also provides a dedicated authorized stockage list and prescribed load list elements for common and exclusive theater signal systems that are not necessarily demand

supported but require intense control and management for the gaining brigade. The following are its repair and support capabilities:

z Modules, circuit boards/cards for high demand, high usage, and low-density theater signal assemblages.

z Automated data processing equipment (including teletype, Tactical Army Combat Service Support Computer System, and associated peripherals).

z HF communications equipment.

z Microwave equipment (including multichannel, TACSAT, and Tropospheric Scatter [TROPO]).

z Fabricates both copper and fiber optic cables for unique

applications.

z Communications security equipment (including a specialized

support activity for selected controlled cryptographic items).

z Ground support equipment (including power generation units with

outputs up to 200 Kw, environmental control units, forced air heaters, power-driven decontamination equipment, and gasoline engines).
