"Successfully supporting the commander with reliable and redundant communications is a direct result of detailed planning."

--FM 11-43, Signal Leader's Guide

Task Force Hawk had a combined arms mission to conduct deep operations. The two major signal tasks were support for the tactical headquarters and support for the units conducting the deep attack missions, successfully validated during combined mission rehearsal exercises (MREs) for aviation and field artillery units. The Signal Corps and a select group of contractors provided the quality support that TF Hawk commanders needed to command and control their forces and to make informed decisions. As part of the TF Hawk main headquarters, the Deep Operations Coordination Cell (DOCC) required a major portion of the support.

In accordance with the Signal support disciplines of Information Mission Area (IMA), the support signal unit used a combination of tactical and commercial systems to provide command, control and communications (C3). The five disciplines of IMA doctrine are 1) Communications, 2) Automation, 3) Visual Information (VI), 4) Records Management, and 5) Printing and Publications. Communications and Automation were the two essential areas required for this operation.

This article focuses on the lessons and Tactics, Techniques and Procedures (TTPs) for TF Hawk signal support, communication, and automation operations. Through brief discussions and five illustrations, this section answers the questions of "How did they communicate?" These answers indirectly identify signal requirements for future deployments with similar missions.

Additionally, TF Hawk signal assets provided digitized "long-haul" and "reach-back" communications as outlined in FM 24-1, Signal Support to Army Operations. Discussed later in this section, the Signal battalion supporting TF Hawk set a significant precedence in customized data support and digitization above the capabilities of Mobile Subscriber Equipment (MSE). In addition, the ACofS, G6 Cell coordinated the many combined arms signal support functions conducted during the operation, including secure and non-secure communications requirements using tactical and commercial assets. These assets were a combination of commercial and government off-the-shelf products and services deployed into theater as well as commercial, Army, and Air Force satellite terminals.

Signal Support Operations

For the first time, an Army operation focused solely on deep operations. The TF Hawk mission required aviation and artillery units to serve as the "main effort" with infantry and armor units providing force protection. Task force signal planners had to overcome the challenge of providing communications over great distances in rugged, mountainous terrain for both attack helicopters during their deep attack and forward deployed artillery forces conducting Suppression of Enemy Air Defense (SEAD) fires. A lack of reliable TACSAT communications in this environment would have been a "show stopper." As a result, TF Hawk received additional TACSATs, including the new AN/PSC-5 SPITFIRE, during its deployment. After working through equipment fielding and training issues, the task force used satellite communications (SATCOM) for the critical link between the decisionmakers and the executors of the mission.

Single-Channel Tactical Satellite (SC TACSAT): The primary TACSAT radios used in this operation were the AN/VSC-7 MST-20 and the newly fielded AN/PSC-5 SPITFIRE. Since AH-64 helicopters lacked TACSAT capability, UH-60 or C12 aircraft equipped with satellite radios provided the communications link between the TF headquarters and deep attack aviation assets during aviation deep attacks. A command and control (C2) UH-60 aircraft accompanied the attack helicopter deep strike package while the C-12 flew as an airborne relay platform. To maintain communications between the forward field artillery assets and TF DOCC, the signal unit deployed AN/TSC-93 and Small Extension Nodes (SEN) forward to the AN/TPQ-37 artillery location radar site and Multiple Launch Rocket System (MLRS) Forward Operating Base (FOB).

Initially, the task force experienced challenges with MST-20 radio repair and SATCOM refresher training. For some time, the task force commander made improving single-channel TACSAT communications a top priority. In fact, TF Hawk cancelled some MREs because of lack of reliable SC TACSAT communications. The Corps continued with the repair and replacement of the MST-20 radios. Meanwhile, the ACofS, G6 expedited fielding and operator training for the new AN/PSC-5 SPITFIRE radio in the Corps. In only a few weeks, TF Hawk received the new radios and were trained to operate them. Figure 1 depicts communications during MREs and planned mission execution.

Figure 1. TF Hawk Communications Architecture.

Key Lesson: Lack of reliable TACSAT communications in mountainous terrain was a show stopper. Fielding the new AN/PSC-5 SPITFIRE during deployment, coupled with training operators on proper use of the equipment, enhanced mission readiness.

Communications

Because of force caps on the task force and requirements to respond to other contingencies, most TF Hawk units deployed only portions of their assets. Since a majority of the unit key leaders deployed forward, task force signal planners had the immense task of building a communications architecture whereby these leaders could continue to provide command and control (C2) for rear detachments and stay-behind assets. Table 1 provides the details for communication support in the task force area. TF Hawk used some of these common communications systems not only to simplify communications between forward and rear elements, but also to boost morale, such as making DSN and NIPRNET available for morale and welfare purposes.

Table 1. TF Hawk Communications Support Matrix.

According to FM 24-1, communications are any transmission, emission, or reception of signs, signals, writings, images, and sounds or any information by wire, light, fiber optics, radio, visual, or other electromagnetic systems. TF Hawk signal support assets provided unparalleled success for combat communications operations using MSE and SATCOM. The ability of the Signal battalion to move large amounts of information over vast distances was so reliable that MSE was deployed forward with key radar and MLRS assets. The MSE assets are normally reserved for headquarters support.

The Signal battalion in support of TF Hawk installed, operated, and maintained a robust and flexible communications network. Although the equipment met all performance expectation, it was the dedication of the unit soldiers and leaders that allowed task force to meet all communications obstacles, such as a harsh environment and restrictive operational parameters. The unit successfully cleared each one with professionalism and ingenuity. The proactive attitude of battalion personnel helped them overcome many issues to include initial entry support.

Initial entry: The Signal battalion provided communications out-of-theater on the very first day of the operation from a "common area" tent. "Ramp-up" field training exercises (FTXs) at home station prepared the Signal battalion to provide immediate support upon deployment. In Albania's austere field environment, the Signal battalion brought all the necessary material and communications assets needed to provide telephone, tactical radio, and computer services. While other organizations worked to set up tents and moved operations vehicles into position, the Signal battalion provided a warm and dry work area with electricity for commanders to place and receive telephone calls and pass data messages. The services included tactical and commercial facsimile, tactical and Defense Switching Network (DSN) telephones, secure and non-secure e-mail, and FM radios. Using initial entry multi-channel TACSAT supported by Military Occupational Specialty (MOS) 31S soldiers, the tent served as a temporary C2center for the task force. Throughout the deployment, multi-channel TACSAT teams remained critical to mission success.

Key Lessons:

  • Multi-channel TACSAT teams comprised of MOS 31S soldiers remained a critical asset that required command attention through initial deployment and sustainment phases of the operation.

  • "Ramp-up" FTXs prepared the Signal battalion to provide immediate support upon arrival in theater, such as setting up a temporary C2center for all unit commanders and executive officers during the initial theater entry phase of the operation.

  • TF Hawk used DSN and Non-secure Internet Protocol Router Network (NIPRNET) to ease the execution of split based operations and boost morale.

Automation

Automation is converting a procedure or process to automatic operations at an exchange, terminal, or local area network (LAN) according to FM 24-1. For this operation, the automation technologies included graphics and word-processing software and files, copiers, telecommunications, printing, data processing, and electronic record systems. Since these were significant data requirements above the capabilities of MSE, the signal team conceived, constructed and maintained an unprecedented data package to support the task force. Completely isolated from the doctrinal tactical packet network of MSE, the data package connected directly to users in the task force headquarters on one end and AN/TSC-85 satellite terminals on the other. To shield it from the environment, to secure information and to maintain the satellite links, battalion personnel applied their resourcefulness and found viable solutions.

Deployable Rapid Assembly Shelter (DRAS) Tent: The DRAS tent can protect data network components from damage because of field conditions and offers more room than a vehicle-mounted shelter. The conditions of the TF Hawk lodgment area were muddy, rainy, dusty, and harsh for both personnel and equipment. Automation equipment used to support the Task Force's data and voice communications requirements was vulnerable to severe damage when exposed to this environment. Four racks of automation equipment provided connectivity for the task force systems. In addition to these environmental concerns, the Task Force also had to guard the system against overheating because of uninterrupted operation. The equipment needed protection in a controlled environment.

The Signal battalion erected the DRAS tent to provide shelter for the data equipment, a procedure that required four to six personnel. The DRAS contained a floor and several windows and doors (with Velcro attachments) that totally enclosed the data racks and kept dust, mud, and rain off the equipment. The tent had approximately 402 square feet of interior useable space, with raw dimensions of 33.25 ft x 13.5 ft x 10 ft. Signal Battalion technicians used electric fans to control the temperature inside the tent.

Custom Data Package: The DOCC and TF headquarters required a wide variety of services that could not be provided at usable data rates by MSE. The data and voice services provided by the data package were long local DSN phones, Automatic Digital Network (AUTODIN), Secure Internet Protocol Router Network (SIPRNET), Non-secure Internet Protocol Router Network (NIPRNET), Video Teleconference (VTC), Contingency Tactical Air Planning System (CTAPS) and Defense Red Switch Network (DRSN). At one time, the total data rate for these systems over tactical satellite was 3,352 kilobytes per second (KBPS). The Tactical Packet-switching Network (TPN) with MSE could not handle these data rates.

To address this challenge, the Signal battalion customized a field data package using AN/TSC-85 multi-channel tactical satellite (TACSAT) terminals, FCC-100 multiplexer/de-multiplexer, modems, codex, multi-rate voice cards, encryption devices, network routers, network hubs, network encryption systems (NESs) and signal drivers. The key piece of the data package was the FCC-100 multiple protocol router, which provided customized data, voice, and video support above the capabilities of the MSE packet network. This single platform was capable of combining functions of voice systems, data systems, and frame relay as a multiprotocol router. The data package, made up of three FCC-100s, provided 256 KBPS VTC, 56 KBPS DRSN, 768 KBPS DSN, 1.2 KBPS AUTODIN, 768 KBPS SIPR, 192 KBPS NIPR, 56 KBPS NATO E-mail, and 64 KBPS CTAPS for the air traffic coordination. Key to the success of this package was its flexibility in reallocating more or less "bandwidth" to particular systems during the operation. For example, the Task Force decided that NIPR was not a required system during MREs. It was inactivated and reactivated at the direction of the ACofS, G6 during predetermined times during the exercise. The three diagrams that follow show signal flow for the data package in support of the TF Hawk headquarters and DOCC.

Figure 3. Signal Flow for AN/TSC-85 #2, FCC-100 (A)

Figure 4. Signal Flow for AN/TSC-85 #2, FXX-100 (B)

Key Lessons:

  • As part of a tactical data network, the FCC-100 multiple protocol router provides customized data, voice, and video support above the capabilities of the MSE packet network.

  • The DRAS tent effectively protected data components of the MSE network from harsh weather effects while providing more room than a vehicle-mounted shelter.
