Summary. In this lesson, you learned about CNR planning and development.
a. Three systems support the ATCCS from corps through brigade. They are the ACUS, ADDS,
b. CNR provides a communications means, independent of MSE, for C2 within the corps in
divisional maneuver brigades, CS units, and CSS units.
c. CNR is designed around the IHFR, SINCGARS, and TACSAT, each of which has unique
capabilities and transmission characteristics.
(1) IHFR, a modular design radio, is used in combat, CS, and CSS units. It gives tactical
commanders an alternate means of passing voice and data communications.
(2) SINCGARS is the primary means for short-range (less than 35 kilometers) secure voice
C below division level. It is the secondary means for CS and CSS units throughout the corps.
(3) Single-channel TACSAT has no planning range, unlike most communications systems,
and its capacity to communicate depends on the location of the satellite for LOS.
d. Units from battalion-level up usually establish three categories of VHF-FM networks (C2,
administrative/logistic, and intelligence). C2 networks are subdivided into the functional areas of
maneuver, fire support, aviation, air defense, and engineers. Units from battalion through division have
a support network to separate operational and administrative/logistics information, thereby preventing
support information from overwhelming the command operations network.
e. In the signal brigade/battalion, CNR operations are conducted in six networks (corps signal
brigade command/operations FM net, corps signal brigade operations HF net, corps and division MSE
battalion command/operations FM net, corps and division MSE battalions' engineering FM net, MSE
company command/engineering FM net, and MSE signal support company/engineering FM net).
f. BSM is managing electromagnetic spectrum resources to support telecommunications and
EW requirements. It includes allocating and assigning generating-frequency resources and distributing
the variables for FH radio systems. Management items include frequencies, TSK variables, net
identifiers, COMSEC variables, and time.
g. The table of frequency allocations provides frequency allocation by type of service. The
frequency manager, with the signal planning element, uses the BECS computer to assign frequencies to
hopsets for HF and VHF radio nets.
h. Zulu (GMT) is the time reference that all networks use.
