h. Non-Mobile Subscriber Equipment (MSE) Division Signal Battalions.
(1) The Heavy Division Signal Battalion.
(a) Overview. As mentioned in Chapter 3 of the FM 11-50 extract, the heavy division
signal battalion is organized into an HHC and three line companies. Refer to Figure 2-3 to see how the
heavy division signal battalion is organized. HHC performs the usual command, control, and logistical
functions. The command operations company, forward communications company, and area signal
company perform specific signal node and signal extension missions. Refer to Figure 2-4, page 2-10, to
see where the signal companies provide support.
(b) The command operations company supports the Div Main CP, Div Rear CP, and Div
TAC CP. Signal support at Div Main CP and Div Rear CP includes the multichannel LOS terminal,
telephone, and switching facilities for trunk and local phone subscribers, cable and wire service, NRI, to
allow single-channel voice radio access to the division telephone system, patch panel, to provide circuit
control, communications center for processing messages, and RATT section. The tactical CP platoon
supports the Div TAC CP with multichannel, RATT, switching, and NRI. The use of two AN/TRC-145
allows the Div TAC CP to jump or displace as needed.
(c) The forward communications company supports the maneuver brigades and five
separate headquarters with multichannel, telephone and switching facilities, cable and wire, NRI, and
RATT. The three brigade extension platoons operate an extension node at brigade headquarters and an
extension node to support a forward support battalion and brigade trains. The separate headquarters
platoon links the air brigade (AB), engineer, MI, air defense, and DIVARTY units to the division
(d) The area signal company is the backbone of the division multichannel
communications network. Each of the three area signal node platoons supports an area signal node. As
mentioned earlier, the area signal nodes interconnect the Div CP, maneuver brigades, the five separate
headquarters, the DISCOM, adjacent divisions, and among each other. These interconnected nodes
provide reliable alternate routing, systems control, and continuity of operations during jumps and
displacements. Flexibility, mobility, and survivability of communications are achieved, greatly
