(2) The Light Division Signal Battalion.
(a) Overview. As discussed in Chapter 4 of the FM 11-50 extract, the light division
signal battalion has unique functions. It generally operates with outside augmentation, e.g., corps signal
brigade assets are used in some systems. The signal battalion may support a division that is employed
over extended distances and in terrain that prohibits LOS multichannel operations. In this situation, the
signal battalion uses tactical satellite (TACSAT) and radio systems with retransmission capability.
Refer to Figure 2-5, page 2-12, to see how the light division signal battalion is organized. HHC
performs the routine functions. Three line companies support the light division. Refer to Figure 2-6,
page 2-13, to see where the signal companies provide support.
(b) The command operations extension company supports the Div Main CP, Div TAC,
and provides one of two area signal nodes for the division ACUS. As a secondary function, it can
provide node support for units through LOS multichannel or cable access. The company provides
multichannel, telephone and switching facilities, NRI, improved high frequency radio (IHFR), RATT,
and TACSAT (in some light divisions). The platoons of this company can be very dispersed and
isolated, thus posing special site security and logistics concerns. Signal soldiers at these remote
locations must establish and adhere to a schedule that addresses systems maintenance, perimeter
defense, and rest.
(c) The forward command extension company provides signal support at the three
brigade CPs and the three brigade support areas (BSA). Services include multichannel, telephone and
switching facilities, NRI, cable, IHFR, RATT, and TACSAT. The company coordinate with the
supported CP for site defense.
(d) The area signal company provides signal support at the DISCOM and five
communications support teams at DIVARTY, AB, air defense battalion, MI battalion, and an additional
headquarters at the division's discretion. This company also provides the second node for the ACUS.
Tactical units in the vicinity of this node can tie into it for access to the network. Services provided
include multichannel, telephone and switching facilities, NRI, cable, IHFR, RATT, and TACSAT for
certain light divisions. Site security can be a shared responsibility when collocated with other divisional
units. However, special security arrangements must be made when the site is an isolated multichannel
relay or retransmission station.
