4-1. The TSC consists of all operational and strategic level signal organizations within the AOR supporting the ASCC. These organizations may include--

• Two to five EAC signal brigades.
• One strategic signal brigade.
• One combat camera (COMCAM) company.
• One theater signal maintenance company.
• One or more reproduction detachments.

4-2. The actual number of EAC signal brigades and the number and type of their subordinate signal units deployed to the theater of operation depend on the METT-TC. Figure 4-1 shows the organization of a TSC.

4-3. The TSC plans, engineers, and manages the Army's portion of the TCS and provides the G6 staff to the ASCC. The TSC is an MSC of the USASC and is under the OPCON of the ASCC.

4-4. The TCS must be flexible and responsive to operational changes if the necessary C2 systems are to be available at the right time and place. C2 tools, such as information systems and VTC capabilities, have become increasingly important to the JTF and ASCC commanders. Complex systems such as these require that the TSC's early entry module be in the theater early to ensure the commander's C2 requirements are met in the very fluid deployment and entry phase of the operation.

4-5. Immediately on the start of contingency operations, the TSC will furnish an early entry module composed of engineers, planners, and operators. Their mission is to plan, engineer, and manage the EAC TCS architecture by coordinating and interacting with the operational planners as they respond to their commander's changing intent and objectives.

4-6. Recent military operations have demonstrated the requirement for timely follow-on deployment of the remaining C2, planning, and engineering capabilities inherent in a TSC, even when there is one or no deployed EAC signal brigades OPCON to the TSC.

4-7. Two types of EAC signal brigades aligned under the TSC that provide global connectivity are--

• Strategic signal brigades. Located in certain theaters and are responsible for fixed, strategic communications support to the warfighter. During peace, each strategic signal brigade is doctrinally under the C2 of the USASC. During MTW or MOOTW, each brigade becomes OPCON to the TSC.

• Theater signal brigades. Deployed to provide mobile, tactical communications support to the ASCC, as required. Upon deployment, the TSC commands each brigade. The mission of this unit is to provide C2 to assigned and attached signal units, and to install, operate, and maintain assigned portions of the TCS as directed by the TSC.

4-8. The TSC provides centralized management and engineering of the entire theater data network. The TSC directs and coordinates local area networks (LANs) as they are connected to the WAN. This includes configuration of databases and domain name servers, to include data network and electronic mail (e-mail) addressing and routing. Figure 4-2 reflects the type of units that the TSC would support.

4-9. The following paragraphs describe the tasking, mission, and capabilities of the HHC TSC.

4-10. The tasking of the HHC TSC varies due to the military operation or situation. In some cases, the CINC may task the HHC TSC to provide overall signal C2, direction, and guidance to a JTF, or apportion elements of the signal mission to the TSC.

4-25. Each theater signal brigade can directly control up to 16 nodes. Figure 4-4 gives an example of a notional theater signal brigade force structure. See Appendix B for further information on this organization.

4-26. The following paragraphs describe the mission and capabilities of the Power PAC3 company (also known as the EAC contingency company). Figure 4-5 shows the unit structure during the intermediate TOE life of the unit. Figure 4-6 shows the objective TOE structure (the desired end-state configuration of the unit after all equipment upgrades have occurred).

4-27. The POWER PAC3 company's mission is to rapidly deploy and support initial information service requirements of the ASCC. Working in concert with deployed Army mobile liaison teams, the organizations are mutually supportive and can meet the entire gamut of communications/ information needs of the ground component commander until the arrival of the TSC. The company can extend US strategic communications systems to support of allied forces.

4-28. The POWER PAC3 company is a critical C2 communications provider, which serves to ensure success during power projection operations. The unit is highly mobile and is tailored to any warfighting ground component commander's mission essential communications and information needs.

4-29. The POWER PAC3 company can deploy into a logistically austere theater with little or no communications infrastructure. The unit must sustain itself for up to 45 days; therefore, the operator/maintainer must maximize all equipment.

4-30. This unit provides--

• Command, staff planning, control, and supervision of the operations of the company to include any augmenting of personnel or material assets.
• Vehicular, electronic, and COMSEC maintenance and repair, as well as supply facilities to support company operations.
• Communications network planning and management.

4-31. On ARFOR deployment, POWER PAC3 company's configuration is determined by mission requirements. Generally, the POWER PAC3 company is broken down into three sections: the ARFOR Main CP, ARFOR Forward CP, and six liaison officer (LNO) signal support teams (SSTs). Each section provides a variety of communications capabilities for the headquarters it supports. Assets from the LNO teams could extend the theater information infrastructure to support other or additional support missions. Figure 4-7 shows the POWER PAC3 company's AOR support requirements.

4-32. The POWER PAC3 company depends on the TSC for health, religious, finance, personnel, administration, petroleum, oils, and lubricants (POL), ammunition, and food services. Army aviation units provide intertheater supplemental air transportation. The company is a modular organization that has a headquarters/contingency company with an LNO team, a heavy hub platoon, and a light hub platoon.

4-33. The headquarters/contingency company has a company headquarters section, network management section, motor maintenance section, CE/COMSEC maintenance section, and LNO team.

4-34. This company is responsible for the C2, management, network engineering, maintenance, supervision, and support of company personnel to include LNO SSTs and any augmentation assets.

4-35. The contingency company engineers the installation of the communications systems required for the ARFOR, supervises and manages the operation of the network, and resolves technical problems.

4-36. The LNO team has six SSTs. Each SST has a super high frequency (SHF) tri-band advanced range extension terminal (STAR-T) team and a retransmission/single-channel TACSAT team. The SST is assigned to an Army LNO team and attached to a designated joint, coalition, or allied headquarters.

4-37. The POWER PAC3 company's LNO signal support team installs, operates, and maintains communications equipment and provides information services to the liaison team. This is done by SATCOM, digital voice switching, and commercial and HN communications access. Each LNO SST is tailored to mission requirements and has a standardized integrated CP shelter.

4-38. Each team has the necessary equipment assigned to them for direct communications back to ARFOR Main CP and/or ARFOR Forward CP. A typical support package provides 32 local secure terminal connections, one local LAN loop, and connectivity to two extended LANs via X.25 ports which support access to the tactical packet network (TPN). For full-scale POWER PAC3 company deployment, these SSTs should provide full information services to 16 subscribers per site.

4-39. This unit is authorized an additional 12 secure telephones and 48 nonsecure telephones with appropriate ASIOE to provide service to those organizations who do not provide their own instruments.

4-40. The heavy hub platoon has a STAR-T section, retransmission/single-channel TACSAT section, line-of-sight (LOS) radio section, future small extension node (SEN) section, and cable and wire section. This platoon is responsible for the following information services (secure and nonsecure) at the ARFOR Main CP:

• Digital voice switching.
• Commercial and HN communications access.
• LOS multichannel radio.
• SATCOM.

4-46. Combat Net Radio (CNR). Secure single-channel TACSAT provides an unlimited range for contingency deployment en route communications, in-theater communications, mobile operations, intelligence broadcast, and CNR users. The ARFOR Main CP, ARFOR Forward CP, and each LNO team have single-channel TACSAT terminals.

4-47. Commercial single-channel TACSAT provides worldwide voice and data access at low- to medium-data rates. The ARFOR Main CP, ARFOR Forward CP, and each LNO team have commercial terminals.

4-48. Improved high-frequency radio (IHFR) systems provide long-haul secure voice and limited low-rate data. Its primary mission is to provide redundant internal C2 and engineering between geographically dispersed signal teams. IHFR is located at the ARFOR Main CP, ARFOR Forward CP, and each LNO team location.

4-49. Secure frequency modulated (FM) radio/Single-Channel Ground and Airborne Radio System (SINCGARS) is located at the ARFOR Main CP, ARFOR Forward CP, and each LNO team location.

4-50. Multichannel Communications. The STAR-T provides multichannel communications connectivity internal to the theater and external between the theater and sustaining base. The transponder-based satellite system operates in the X (DSCS), C, and Ku (commercial) SHF bands. The ARFOR Main CP, ARFOR Forward CP, and each LNO team have STAR-T terminals. The STAR-T has an integrated switching capability, supports local subscribers, terminates digital trunk groups (DTGs) from LOS terminals and other STAR-Ts.

4-51. The AN/TSC-143, (tri-band) terminal is the prototype STAR-T and will be fielded as an interim solution. It has embedded switching which functions as both tandem and private branch exchange (PBX). It will replace the current AN/TTC-39 and AN/TTC-48 switches and the AN/TSC-85 and AN/TSC-93 satellite terminals.

4-52. The STAR-T will replace the currently fielded multichannel TACSAT assets. During the transition, the STAR-T interoperates with the AN/TSC-85 and AN/TSC-93 SATCOM terminals. These terminals provide low-, medium-, and high-capacity multiplexed data and voice circuits and can be used in point-to-point, hub-spoke, and mesh networks. These terminals operate in the military portion of the SHF X-band frequency range over the DSCS and can only interface with the STAR-T in the X-band.

4-53. The POWER PAC3 company uses LOS equipment to interface with the STAR-T integrated switch. It will be used at the ARFOR Main CP to allow for geographical dispersion of site circuits throughout the CP AOR.

4-54. HN and Commercial Communications. HN and commercial communications has local switching centers, loop distribution networks, and interswitch transport systems (radio, cable, fiber optics, and satellite). HN systems vary from country to country, but basic international standards apply.

4-55. Tactical Packet Network. The TPN is a data network made up of interconnected packet switches overlaid on the circuit switched network. Users access the TPN by directly connecting to the packet switch or to a LAN. The TPN provides users the ability to pass data throughout the battlefield and back to the sustaining base through defense integrated secure network (DISNET) 1.

4-56. The STAR-T located at the ARFOR Main CP, ARFOR Forward CP, and each LNO team site provides packet switching. The STAR-T has an integrated packet switching capability and supports users via LANs. Additional users can connect directly to the packet switch or through dial-up into the circuit switch.

4-57. Mobile Gateway Van. The absence of multilevel security (MLS) prevents users on the TPN from sending and receiving e-mail messages to the sustaining base through the unclassified NIPIRNET. The MGV provides an interim solution for tactical users.

4-58. The MGV provides a tactical extension of the unclassified NIPIRNET for tactical users through router technology/packet network. The MGV provides users e-mail, file transfer, and telecommunications network (TELNET) capabilities over the NIPIRNET.

4-59. Two MGVs are available for each POWER PAC3 company. The MGV will provide NIPIRNET access to all users on the battlefield. The data team located at the ARFOR Main CP installs, operates, and maintains the MGV.

4-60. Down-Sized Message Switch. POWER PAC3 company provides messaging capability via DMS products directly connected to the tactical network which may be used for sending and receiving both general support (GENSER) (R) and DSSCS (Y) formal record traffic.

4-61. Users can access the switch directly through an encryption device or by dialing the circuit switch with a secure telephone. Subscribers without a direct or dial-up connection can send and receive messages directly from the message center (over-the-counter). The message center is located at the ARFOR Main CP.

4-62. Tactical VTC System. VTC service with worldwide connectivity is possible through tactical communications systems. Recent lessons learned demonstrate enhancement of the commander's span of control through VTC support. A deployed commander can meet face-to-face with either subordinate or senior commanders on a moment's notice through tactical VTC systems. Secure networks support these systems. A tactical VTC system would be based out of the ARFOR Main CP and provide connectivity with the Forward and LNO sites and as strategic locations via network gateways.

4-63. Emerging technology has made VTC communications an extremely viable combat multiplier for the commander. As additional services become available, they will be integrated with POWER PAC3 company's capabilities.
