Tactical Nets
Provide the commander with the
means of commanding and controlling his subordinate maneuver
The radio should never be
used as a substitute for thorough planning and preparation, but as the voice of command.
Infantry Platoon Tactical Net (VHF)
Stations on the net include the platoon leader, squad leaders, and any fire teams operating away from the platoon, e.g., SPs, LPs. (Inter-Squad Radio (ISR), SINCGARS)
Infantry Company Tactical Net (VHF)
Stations on the net include the company CP, company OP, rifle platoons, weapons platoon, and attached or supporting units (as required) and call for and to direct 60mm mortar fire.
Infantry Battalion Tactical Net #1 (VHF)
Stations on the net include
the battalion CP, the battalion commander (with his radio operator), rifle companies, weapons company (as required), and attached or supporting units (as required).
Scout Sniper Command Net (VHF)
Stations on this net include the Scout Sniper Platoon Commander, the Scout Sniper Platoon Sergeant, and the scout sniper team leaders.
Administration and Logistics Nets.
means to pass logistical
traffic (e.g. requests for resupply of chow, fuel, water,
ammunition by the company gunnery sergeant) and
administrative traffic (e.g. morning reports, casualty reports by the company first sergeant).
Infantry Battalion Tactical Net #2 (VHF)
This net provides the battalion commander with a means of exercising administrative or logistical command and control over his subordinate units. It also functions as a secondary tactical command and control net.
Fire Support Nets 4:
1 Infantry Battalion Mortar Net (VHF)
2 Artillery Conduct of Fire Net (VHF)
3 Tactical Air Direction/Helo Direction (TAD/HD) Net (UHF/VHF)
4 Tactical Air Control Party (TACP) Local Net (VHF)
All fire support nets (air, naval gunfire, artillery, mortars) are monitored in the
fire support coordination center (FSCC)
Infantry Battalion Mortar Net (VHF)
provides the means by which the 81mm mortar forward observer calls for and directs
81mm fire - located within the battalion COC.
Artillery Conduct of Fire Net (VHF)
Stations on the net include the FOs, the artillery liaison
officer in the FSCC, and the direct support artillery battery fire direction center (FDC).
Tactical Air Direction/Helo Direction (TAD/HD) Net (UHF/VHF)
primary means for the Forward Air Controller (FAC) to direct the aircraft in the conduct of the close air support/close in fire support mission. Stations on the net include the FAC, the AO in the FSCC, and the aircraft. (AN/PRC-113, AN/PRC-117, SINCGARS)
Tactical Air Control Party (TACP) Local Net (VHF)
primary means for the FAC to request air support from the air officer (AO) located in the FSCC. The FAC and the AO also pass administrative traffic to each other over this net (e.g. Bomb Damage Assessment). Additionally, anyone operating a VHF radio can use this net to request air support from the AO. (SINCGARS)
Command Post (CP) at the platoon level
• Platoon commander
• Platoon sergeant
• Radio operator
rifle company level - same set up with the addition of
• Fire support team (FiST)
• Executive officer
• Gunnery sergeant
• First sergeant
battalion level there are usually two types of
combat operations centers (COCs):
infantry battalion level - Main COC:
commanded by the battalion executive officer
• S-1: Administration
• S-2: Intelligence
• S-3: Operations (which includes the Fire Support Coordination
• S-4: Logistics (including Medical)
• S-6: Communications
infantry battalion level - Tactical COC:
commanded by the battalion commander
• S-3 Officer or “actual”
• S-2 Officer
• S-6 Officer
• Air Officer
• Associated communications personnel and clerks from the
different primary staff sections.
Fire Support Team (FiST) comprised
• FiST leader-weapons platoon commander (lieutenant)
• Forward air controller (FAC)
• Artillery forward observer (Arty FO)
• 81mm mortar forward observer (81s FO)
The FiST leader maintains
(lieutenant) communication with the company commander on the company TAC net.
Forward air controller (FAC)
(captain who is a naval aviator) requests close air support from the air officer who is located in the fire support coordination center back at the battalion COC. The FAC requests this air
support using the TACP local net. Once the aircraft checks in on station, the FAC uses the TAD net to provide terminal guidance to the aircraft.
Artillery forward observer (Arty FO)
(lieutenant from the direct support artillery battery) responsible for calling for and adjusting artillery fires in support of the ground scheme of maneuver. He calls for fire to the artillery battery on the artillery conduct of fire net; once the rounds impact on or near the
target, he adjusts the rounds using the same net. The Arty FO normally has an RTO and a 0861 Scout Observer.
81mm mortar forward observer (81s FO)
(corporal from 81mm mortar platoon) responsible for calling for and adjusting 81mm mortar fire in support of the ground scheme of
maneuver. He calls for fire to the 81mm mortar platoon on the battalion mortar net; once the rounds impact on or near the target, he adjusts the rounds using the same net.
A radio net is:
two or more stations operating on the same frequency for the specific purpose of exchanging information.
The Net Control Station (NCS) is responsible for:
• Overall supervision of the net
• Opening and closing the net
• Granting and denying entry to the net
• Correcting errors made on the net
• Maintaining discipline on the net
• Maintaining the radio that acts as the master-timing source for all stations on the SINCGARS radio net
Administrative Call Signs
• Used in non-tactical situations where security is not critical
• Normally do not change on a regular basis (pilots often have an intrasquadron
call sign that they use on the squadron-common radio net)
• TBS uses on the range safety net
Tactical Call Signs
• Tactical call signs are used as unit designators on secure radio nets. They are originated by the units themselves but these call signs must be approved at the national level to ensure that in a large scale conflict call
signs will not be duplicated.
• Are assigned down to the platoon level
• Can be an alphanumeric call sign (e.g. “A9G”) or a call word (e.g. “Ripper”)
A collective call sign is a
letter-numeral-letter designator (such as O8I) or a call word used to call all of the stations on the net.
Free call sign
• Member stations
ο Do not have to request permission from the NCS to transmit
ο Required to advise NCS when they have to drop off the net for any reason
• Is the most commonly used tactical net at the small unit level
• NCS opens at a predetermined time:
ο All stations monitor the frequency
ο NCS transmits the net call sign
ο Stations answer in alphabetical order
ο NCS notifies the net that their transmissions have been heard
ο Net is now open for traffic
Directed call sign
• NCS strictly controls all traffic
• Member stations must request permission from NCS to transmit any traffic to
stations other than NCS
The drafter is the person who actually writes the message.
The originator is the command whose authority sends a message.
Releasing Officer
The releasing officer is the person that is authorized to release messages from the command.
Parts of a message
• Heading
• Precedence
• Date-time-group (DTG)
• Originator
• Addressee
• Classification
• Main body
• Ending
• Precedence 4:
routine (R), priority (P),
immediate (O), and flash (Z)
two types of addressees are
action and info
Considerations when drafting or receiving messages.
• Accuracy
• Brevity
• Elimination
• Substitution
• Abbreviation
• Clarity.
The ending of the message contains the __ __ __ . If a message is __, the radio
operation will not transmit it. Furthermore, the releasing officer
needs to verify the message to ensure it is accurate. The
signature also serves as a __ __ __ __ for that particular message.
releasing officer's signature - unsigned - point of contact (POC)
ANT (antenna) connector. Connects to the manpack antenna or vehicle antenna cable.
Connect to handsets through the AUD/DATA (audio/data) Connector or AUD/FILL (audio/fill) Connector.
DIM Control. Adjusts display brightness. The knob is turned clockwise to brighten the display and counterclockwise to dim the display.
RXMT (retransmit) Connector. Connects to another RT during retransmit operations.
STBY (stand by). The STBY position will cut the primary (battery/vehicle) power to the RT. The RTs battery (hub battery) will maintain the memory of the radio including frequencies and times. This position is used as an alternative to OFF when the operator is concerned about conserving power during non-operating periods, but wants to retain all of the data loaded for operations occurring in the near future (same day).
TST (test). When this position is selected, the RT conducts a self- test of it's internal circuits. At the completion of the test, the radio will display results. Whenever the radio is put into operation, the operator should conduct a self-test.
LD (load). Putting the radio in this position allows the operator to load frequencies, data and COMSEC into the radio. In order to load any of this information into the radio for use, the operator must ensure that LD is positioned so the radio will receive the input.
SQ ON (squelch on). This turns on the RT and the squelch. This feature will prevent the rushing noise from being heard in the handset/helmet. This is the normal operating position for the SINCGARS radio.
SQ OFF (squelch off). Mandatory if talking to range control
Z-FH (zero-FH). 1st step in zeroing data! Placing the function switch in this position and waiting 5 seconds will clear all of the FH data within the radio.
Use 8 different frequencies for "Single Frequency"
Single Frequency
Can only utilize 123456 for frequency hopping
Frequency Hopping
SC (single channel)- 5 Digits
FH (frequency hopping) - 3 digits
FH (frequency hopping) - 3 digits
PT (plain text). Keyword: Clear or not secure
CT (cipher text) Keywords: Vinson or crypto
Z (zero). SECOND STEP IN ZEROING RADIO !! Used to clear the COMSEC fills. When turned to Z, the fills in channel 1-5 are instantly cleared. After 5 seconds in the Z position, the key in channel 6 is cleared.
