CHAPTER 2

FUNDAMENTALS

Long-range surveillance units use infantry and ranger skills combined with skilled communication operators and intelligence personnel to collect and report battlefield intelligence. The fundamentals of LRS operations are command and control, communication, mission development, and operational security.

Section I. COMMAND AND CONTROL

Command and control (C2) is the process of directing and controlling military forces. For LRSU operations, C2 must be effective during all conditions, especially across the operational continuum with a special emphasis of operations conducted during the enemy's use of electronic warfare. (Figure 2-1.)

2-1. STRUCTURE

The LRSU's C2 system is structured for rapid deployment and collecting and reporting information. Communication, SOPs, and training to standard are critical to the success of C2.

a. The LRSC is organic to the tactical exploitation battalion of the military intelligence brigade. The corps G2 in coordination with other staff sections determines mission requirements for the LRSC.

b. The LRSD is organic to the MI battalion of the division. The division G2 in coordination with other staff sections determines mission requirements for the LRSD.

2-2. MISSION TASKINGS

Efficient C2 allows the LRSC taskings from the corps or and the LRSD to respond quickly to mission division G2 (collection management and dissemination [CM&D] section). Missions assigned to LRSUs support corps and division commanders' priority intelligence requirements (PIR) and information requirements (IR) as stated in the collection plan. The commander's PIR govern the organization and conduct of reconnaissance, surveillance, target acquisition} and damage assessment operations. First priority usually goes to the information required for continuous operations. The faster the change in battlefield conditions, the more important reconnaissance, surveillance, target acquisition, and damage assessment operations become. The PIR serve to focus the unit's collection effort on the most important features of the enemy and terrain. Intelligence collection efforts provide the commander with a complete and accurate picture of the total battlefield. The PIR and IR are the basis for collection operations; they are analyzed by the all-source analysis section in conjunction with the IPB. The all-source analysis section develops indicators for each PIR and IR. (Indicators are any evidence of enemy activity or any characteristics of the area of operations that point toward enemy capabilities, vulnerabilities, or intentions.) From those indicators, statements or questions are derived that will satisfy specific information requirements (SIR). These questions or statements form the basis for specific LRS taskings. (For more information, see FM 34-8.)

a. Sound tactical planning and operations depend on intelligence. The corps and division G2s plan and coordinate collection capabilities and other intelligence functions to give corps and division commanders the ability to see and fight throughout the depth of the battlefield. The commander can then consistently make decisions faster than the enemy. The corps and division intelligence systems support operations by obtaining specific information required to confirm or deny indicators to satisfy the commander's PIR. The LRSU is tasked to collect information on surveillance targets to satisfy some of these SIR. The G2 ensures that assigned LRSU targets satisfy both PIR and IR and offer a reasonable chance of mission accomplishment and team survivability. Examples of possible targets are--

In operations other than war, the tasking procedure does not change, but types of surveillance targets do. Targets in an operation other than war environment include infiltration routes, supply bases, training bases, and assembly areas.

b. The G2 tasks the LRSU by input to paragraph 3 of the corps or division OPORD, FRAGO, or freetext message. (See Section III for LRS planning.) (See Figure 2-2.)

2-3. TYPES OF MISSIONS

LRSUs are tasked to conduct several different types of missions to satisfy G2 collection requirements. Although surveillance is the primary mission, LRSUs can also perform limited reconnaissance, target acquisition, and battle damage assessment. Weather and terrain conditions reporting is an inherent capability of LRSUs. LRSUs can also perform in limited collateral activities such as pathfinder operations and combat search and rescue operations. The individual unit METL defines the mission it must perform. Surveillance teams use stealth in conducting their missions. Movement within the target areas is limited to mission accomplishment. In restricted visibility conditions, observers may move closer to the target area. Surveillance teams can be assigned the following missions.

a. Surveillance. Surveillance is the primary LRS mission. Surveillance sites are established using mission, enemy, terrain, and troops and time available (METT-T) factors. Stand-off from the target is desirable, but METT-T factors may dictate the positioning of the surveillance site close to the objective. METT-T factors may also dictate multiple surveillance sites to compensate for daily changes in terrain, weather, and light. Surveillance is either maintained for a specified period or until the required information is obtained.

b. Reconnaissance. Surveillance teams can conduct limited reconnaissance missions. Reconnaissance missions are area, zone, and route. Movement by teams is minimized to avoid detection. (See Appendix B for specifics on reconnaissance.)

c. Target Acquisition. The detection, identification, and location of key enemy targets may be a mission of LRS teams. In addition to the acquisition of specific targets, teams may emplace sensors or other unattended devices.

d. Damage Assessment. The LRS team members are trained and equipped to conduct tactical damage assessment. They can conduct chemical and radiological monitoring if equipped.

e. Terrain and Weather Reporting. The LRS team can provide accurate terrain data and current weather conditions in and around potential targets. Human intelligence on current conditions helps greatly to ensure success of operations. (See Appendix C for information on operational environments.)

f. Collateral Activities. The LRS team can also conduct disaster relief, coalition support, combat search and rescue, and pathfinder operations.

2-4. LEADERSHIP

Leadership gives purpose, direction, and motivation in combat. A leader's competence and confidence results in effective unit action. A leader must know how to analyze the situation quickly and make decisions rapidly.

a. Long-Range Surveillance Company. LRSC leadership includes the company commander, executive officer, operations officer, intelligence officer, first sergeant, liaison noncommissioned officer, chemical noncommissioned officer, communications platoon leader, surveillance platoon leaders, platoon sergeants, and team leaders.

b. Long-Range Surveillance Detachment. The LRSD leadership includes the detachment commander, executive officer, detachment sergeant, detachment communications sergeant, detachment operations sergeant, base radio station section chief, and team leaders.

2-5. SURVEILLANCE TEAM OPERATIONS

Long-range surveillance teams operate within the area of operations of their respective corps or division.

a. The specific operational area is identified and coordinated for each mission. The target, in conjunction with the insertion and extraction plan, determines the area in which a team operates. This area is not so large that it unduly restricts the employment of corps or division assets, but it is large enough to give the team flexibility. LRSD teams are employed forward of the forward edge of the battle area in the division area of operation. The LRSC teams are employed in the corps area of operation forward of the detachment teams. The distances LRSD and LRSC teams operate forward of the forward edge of the battle area vary depending on terrain, operational tempo of the battlefield, and intelligence needs of the commander. (See Figure 2-3.)

b. Operations by teams in areas forward of friendly soldiers can create possibilities for fratricide. To protect the LRS teams from friendly fires, the following coordination is conducted before insertion.

2-6. OPERATIONS BASE

The operations base is a location from which the LRSC or the LRSD operates. (See Figure 2-4 for an example long-range surveillance company or detachment operations base.) The LRSC operations base locates with or near the CM&D section of the corps G2. The LRSD operations base locates with or near the CM&D section of the division G2.

a. The operations base for the LRSC and the LRSD are similar. They include areas for a TOC, company or detachment headquarters, communications platoon or base radio station, motor park, isolation facility or area, LZ, and platoon or team defensive areas.

b. The primary mission of the AOB is to act as communication relay for the COB or DOB and deployed LRS teams. The AOB planning considerations are based on communication requirements of the COB or DOB and the deployed LRS teams.

c. The company commander selects the general location of the LRSC COB and AOB.

d. The detachment commander coordinates a location at or near the division main command post for the DOB. He also selects the general location for the AOB.

2-7. TACTICAL OPERATIONS CENTER

The LRSC and the LRSD TOCs set up in the operations base. They give LRSU commanders a command and control capability and a communication with higher headquarters capability.

a. LRSC TOC Organization and Responsibilities. In the LRSC TOC, personnel perform specific functions as follows.

b. LRSD TOC Organization and Responsibilities. In the LRSD TOC, the commander, executive officer, detachment sergeant, operations sergeant, and communications personnel perform all functions.

c. Operations (LRSC or LRSD). Before each mission, the TOC personnel (operations, intelligence, and communication) are prepared to--

2-8. TASK ORGANIZATION

The LRSCs and LRSDs assigned to corps organizations use the same company-level SOPs and communication procedures. Therefore, the corps commander can task-organize LRS assets as battlefield conditions change. LRSC and LRSD teams initially are employed in their respective areas of interest. The rapid pace of operations may require the LRSC and LRSD to coordinate command and control of deployed LRS teams and exchange information to meet the intelligence needs of the commander.

a. Echelons Above Corps. During retrograde operations, command, control, and communications of LRS teams beyond the corps area of operations is given to echelons above corps. This action requires a liaison with a radio station from a LRSU AOB to locate with echelons above corp controlling headquarters. Control of extracted teams is returned to the parent LRSU.

b. Brigade Task Organization. An LRSD, or portions of an LRSC, are under operational control of a brigade for certain operations. This OPCON occurs as part of a contingency operation. It most often occurs in an operation other than war environment and before the main control cell of the G2 deploys to the area of operations. It also occurs when brigades expand control of a sector and deployed LRS teams are operating in that sector. When this situation occurs, a liaison with a base radio station from the COB, DOB, or AOB locates with the brigade TOC. A G2 CM&D liaison may accompany the LRS control element for mission planning.

Section II. COMMUNICATIONS

The accurate and timely reporting of information by the surveillance teams is the most important aspect of the LRSU mission. Without communications, there is no reason to insert a team deep into the enemy's rear area. Well thought out, planned, and practiced communication procedures helps ensure the success of a mission. Communication is a two-way event and everyone must know the procedures.

2-9. COMMUNICATION NETS

The LRSU team deploys out of line-of-sight communication range. Ordinary combat net radio systems cannot support the reporting requirements of the LRSU. Tactical FM radios, like single-channel ground and airborne radio system, must be in sight of each other electronically to communicate.

a. LRSUs must rely on and train with communication systems with extended range capabilities. Two systems available in the Army system are HF and tactical satellite radios.

b. The COB or DOB and their respective AOBs maintain communication with employed teams using HF radio. Each team has a separate frequency and cryptographic for OPSEC purposes. Communication between the two operations bases is maintained using the tactical switching system between the two locations. Backup communication between the base operations is maintained using either line-of-sight or HF radio systems as METT-T requires. The LRSC communication net has 18 teams and eight AN/TSC-128s. Figure 2-5 shows the LRSD communications net.

c. The COB or DOB maintains communication with their G2s using the tactical switching system and with combat net radio in the corps or division intelligence net.

d. Communication within the operations bases is accomplished with an internal wire net (Figure 2-6). The unit's communication personnel establish this net using organic wire and telephones.

2-10. MESSAGES AND REPORTS

The base radio station communicates with teams during specified communication times. A separate time is established for each team. The number of scheduled times used by the LRSU depends on METT-T. The employed team must be protected from enemy interception and direction finding. Too many scheduled times put a team at risk, while not enough scheduled times could minimize the importance of time-sensitive intelligence. OPSEC demands must be weighed with frequency availability.

a. In addition to scheduled communication times, an HF guard frequency is established. The base radio station monitors the guard frequency 24 hours a day. The guard frequency provides the teams with a second frequency for transmitting outside the scheduled time, when communication on the primary frequency cannot be established. The guard frequency changes periodically to accommodate changes in the atmosphere, but changing it more than twice a day is not recommended; one frequency for daytime operation and one for nighttime operation is suggested. Instances where a team may use the guard frequency include--

b. The base radio station and teams communicate using data-burst devices; for example, the OA-8990 digital message device group (DMDG) and the KL-43C. A data-burst device sends messages over the radio as quickly as possible. The shorter the transmit time, the less likely a team will be detected by enemy direction-finding equipment. Interception is also a major concern of the LRSU. Data-burst devices do not preclude the enemy from intercepting the radio traffic. To minimize the effectiveness of enemy interception, teams and the base radio station encrypt messages. The DMDG has no internal cryptographic capability, so teams use a one-time pad with a trigraph to encode messages before sending them. The KL-43C has an internal cryptographic capability and does not require the team to manually encrypt the message. In addition to encrypting the message, teams can use brevity codes to assist in shortening the message. However, brevity codes increase the message processing time and increase the possibility for error.

c. Message formats between teams and the base radio station are part of the SOP. If a message has an exacting format, even a partially received message is useful, because it is recognizable. The following is an example of the messages a team should be prepared to transmit during a mission. (See Appendix D for illustrations.) (See the Special Forces SOI supplemental instructions for additional message formats.)

d. Intelligence reports received by the base radio station go directly to the corps or division G2. The LRSU operations base does not delay or change any intelligence report. If a message is received by the base radio station at the AOB and not the COB or DOB, the message is sent by the fastest, secure means to the corps or division G2 and the COB or DOB exactly as received. (See Figure 2-7.)

2-11. BASE RADIO STATION OPERATIONS

The primary mission of the base radio station is to receive and transmit messages between the operations base and employed teams. Each base radio station monitors all deployed team frequencies. The AN/TSC-128 is the basic system for the base radio station. Two AN/TSC-128s makeup one base radio station. Each AN/TSC-128 maintains communication to three LRSU teams. To accomplish this, the AN/TSC-128 is equipped with three HF radios (AN/GRC-213) to receive communication from deployed team and one HF radio (AN/GRC-193) to transmit to the teams and other stations. In addition, the AN/TSC-128 is equipped with four DMDGs or KL-43Cs, one UGC-74 teletype terminal, one VRC-series radio (or mobile radiotelephone for mobile subscriber equipment), and a UGC-7 facsimile machine.

a. The LRSC establishes two base radio stations at the COB and two at the alternate sites. The LRSD establishes a base radio station at the DOB and at an alternate site. The base radio stations at the COB or DOB are the primary link to teams in the field. The base radio stations at the AOB serve as backup. They are prepared to receive messages the COB or DOB cannot, take over the mission if the COB or DOB displaces, and take over the mission if the COB or DOB is destroyed.

b. The success of HF communication often depends on the type of antenna erected. The best antenna is resonant to the transmitter frequency. The antenna cut to the proper length adds gain to the antenna and increases the success of communication. The base radio station will have the terrain, security, and time to construct matching full-wave and half-wave antennas. Employed LRSU teams often compromise in their antenna selection, depending on METT-T. The base radio station takes all actions necessary to ensure communication. The base radio stations at the AOB build different types of antennas than the COB or DOB. This adds flexibility and provides different paths for transmission. (See Appendix D for more information.)

c. Constant communication between the COB or DOB and AOB is necessary. The AOB must be ready to assume the mission of the COB or DOB and must track the battle. The primary communication link between the COB or DOB and the AOB is the corps or division tactical switching system. As a backup, the base radio stations at the COB or DOB and the AOB maintain communication with tactical FM radios using the published frequencies in the SOI and with their HF radios using the HF guard frequency. Message traffic between the two stations is sent by data burst, facsimile, teletype, or secure voice.

d. COMSEC is management intensive for LRSU operations. Each team has individual cryptographic for communicating with the base radio station. In addition, local nets have their own cryptographic requirements. The LRSC or LRSD commander ensures the unit's COMSEC custodian keeps the proper material in the correct amount on hand, both for training and contingency missions. Possible COMSEC keys needed for LRSU operations are--

e. In addition to cryptographic, LRSU COMSEC requires intensive frequency management. The nature of HF communication and the OPSEC requirements for LRSU teams places a high demand on multiple HF allocations. HF reliability changes with the time of day, time of year, position of the transmitters on the earth's surface, and the type of equipment used. Good OPSEC demands different frequencies for each team employed and a separate frequency for the HF guard. For an LRSC, that can mean as many as 19 frequencies at a given time of day and as many as 7 for the LRSD. The LRSU commander coordinates with the corps or division signal officer to ensure the LRSU is allocated the frequencies it needs for the mission.

f. Each base radio station maintains a log of all messages. The team chief ensures all messages for committed teams originate from the operations section. When a team message is received, the operator logs in the message, then forwards it to the operations section for decryption. If there is an outgoing message for a team, the operation section encrypts it. The operator then transmits it to the team during the team's next scheduled communication time.

2-12. SURVEILLANCE TEAM COMMUNICATIONS

HF radio is the surveillance team's primary means of communication with the base radio station. Data-burst equipment is used to shorten transmission times. Encryption systems are used to preclude enemy interception. In addition to HF radio, teams use tactical satellite assets when available.

a. The RATELO selects the communication site, with the team leader's approval, using METT-T. Communication site considerations are security, cover and concealment, space to erect an antenna, and an escape route.

b. Teams transmit and receive routine messages during the scheduled communication times. For messages requiring transmission outside the time schedule, the team first tries to transmit on the designated team frequency. If communication cannot be achieved on the team frequency, the team then transmits on the HF guard frequency.

c. Internal communication within the team is maintained using secure FM and visual and sound signals. (See Appendix E.) Leaders ensure proper OPSEC and COMSEC precautions are followed.

2-13. ELECTRONIC WARFARE

Electronic warfare is a military action used to prevent the enemy's use of the electromagnetic spectrum, while retaining friendly use of the spectrum. This is accomplished through both offensive and defensive measures.

a. Offensive electronic warfare operations include the use of electronic warfare support measures and electronic countermeasures.

b. Defensive electronic warfare operations include electronic counter-countermeasures (ECCM). ECCM are actions taken to ensure effective use of the electromagnetic spectrum despite electronic warfare activity by the enemy.

c. To protect themselves from enemy electronic warfare activity, LRSUs apply ECCM. ECCM have two categories: preventive and remedial.

Section III. MISSION DEVELOPMENT

Long-range surveillance missions are specific, require detailed planning, and support the collection plan of the supported corps or division. All LRSU missions are carefully planned and coordinated to prevent duplication of effort, conflicting requirements, and the possibility of overlapping or intermingling with other friendly forces in the area. Corps ensure LRSC missions do not conflict with subordinate division LRSDs, between divisions, or with the echelons above corp special operations forces. Divisions ensure LRSD missions do not conflict with friendly forces working in their area.

2-14. PLANNING

The LRSU commander or his representative (liaison officer, operations officer, operations NCO, or platoon leader) assists the intelligence and operations sections of the division or corps headquarters in the initial planning for LRS missions. Methods of operations while deployed, communication procedures, reporting, and other standard practices are in the LRSU SOP. An LRS team normally requires 24 to 48 hours planning time to execute a mission. The recommended planning time is often not available. The following minimum-essential information is provided for hasty mission execution:

a. Special Considerations. METT-T guides the planning for LRS operations. The reverse planning sequence is used during planning. Among the many planning considerations, the following are particular to LRS operations.

b. Detailed Planning. G2, G3, and LRSU operations personnel prepare the detailed mission folder according to guidance from the commander and the controlling headquarters. Selected team leaders, a representative from the units providing transportation, SEAD, and fire support are briefed early in the planning phase. They should also participate in the detailed planning that follows. During briefings, team leaders are furnished minimal information about friendly units to maintain OPSEC. Essential details of the LRS team plan normally include the following.

2-15. COORDINATION

Throughout planning, coordination is made with the following elements at the TOC of the controlling headquarters.

a. Intelligence Element. The detailed patrol plan is given to the G2 element. An update on the enemy situation, terrain, and weather forecasts must be added to the mission folder. A final check is made of the LRSU plans and the plans of other information-gathering agencies to make sure all collection elements of the unit's intelligence plan are coordinated. Coordination is made with other units and staff elements.

b. Operations Element. The patrol plan is also given to the G3 element. The latest information is obtained on the friendly situation. For security reasons, only essential information is provided to the team. The G3 element is responsible for initial coordination with the unit providing transportation for the LRS team. The G3 element coordinates as necessary with the division air management element, Air Force liaison, and naval gunfire liaison.

c. Division or Corps Fire Support Element. The location of the team is coordinated with all fire support elements to ensure personnel safety. Constant coordination ensures the team's safety during employment of conventional nuclear or chemical weapons. Procedures are set up for processing LRS team calls for fire and informing teams of planned fires and passive protection measures to be adopted. In addition, requirements for target damage assessment and reporting procedures are coordinated, and a fire support plan is completed for each LRS team. Team locations must be coordinated with division fire support coordinator so that the location can be designated as no-fire areas or restrictive-fire areas. This information is disseminated to units on a need-to-know basis.

d. NBC Element. The NBC element is given the location of all committed teams, and plans are coordinated for monitoring requirements in the area of the team's operation. Information on contaminated areas is distributed as necessary.

2-16. WARNING ORDER

After the unit has been alerted for a mission, the operations section of the LRSC, or the LRSD commander, issues a warning order (mission alert notification) to one of the platoon leaders (LRSC) or the team leader (LRSD), and finalizes the mission folder. The warning order is based on the commander's guidance. The surveillance platoon leader in the LRSC designates a team for the mission and issues a warning order to the team. In the LRSD, the commander selects the team. Upon receipt of the OPORD and after issuing a warning order, the team leader coordinates the following requirements with the platoon leader or the platoon sergeant (LRSC), or the detachment commander (LRSD), as applicable:

Section IV. OPERATIONAL SECURITY

Avoiding detection by the enemy and the populace is a prime requisite for the success of LRS operations. LRSU subelements and supporting elements must rely extensively on OPSEC measures.

2-17. TACTICAL AND ADMINISTRATIVE MEASURES

Control of information pertaining to past, present, and future LRS missions is important. Periodic security orientations and inspections, including communication elements and procedures, are conducted regularly to make sure that OPSEC requirements are understood and followed. Tactical security and deception measures necessary to teams and their support elements include the following:

2-18. ELECTRONIC MEASURES

Radio intercept and radio direction finding are the primary methods of gathering intelligence through electronic means. Radio intercept entails monitoring and understanding message content. Radio direction finding locates transmitting stations by tracking their signals.

a. Many potential adversaries have an extensive intercept capability for electronic transmissions. They can intercept transmissions within the following distances from the forward edge of the battle area:

NOTE: These ranges are greatly extended when airborne intercept is employed.

b. Ground-based and airborne intercept equipment available throughout the world is technically sophisticated, rugged, and easy to maintain. Enemy forces must be considered to have a modern intercept capability.

c. Enemy direction-finding capability is comparable to their intercept capability. Various types of mobile, directional antenna systems can be used in a radio direction-finding role. Forward-area mobile elements include a VHF tactical radio direction finder with an Adcock antenna, as well as the pole dish radar direction finder. Tactical FM radios operating on low power can be detected by radio direction-finding units for more than 10 kilometers and high-power signals can be detected at distances up to 40 kilometers. Radio direction finding is usually accurate within plus or minus 3.5 degrees.

d. Direction finding is used--

e. Figure 2-8 illustrates enemy ground-based electronic intercept and direction-finding capabilities. Once begun, the targeting sequence can continue even if friendly communication cease. The location of radios transmitting in excess of 20 to 25 seconds will be plotted within two to three minutes of the intercept. LRS team members must be aware of this and must adhere to approved operating procedures.
