Most are transportable by air.

c. Generators.
In order to operate the multichannel equipment
from a mobile format, you must have a reliable, available power
source. Generators, usually mounted on a trailer as part of a power
unit, serve this requirement well.
Various models of generators,
assembled into generator sets, meet the power requirements to operate
the mobile multichannel equipment.
Typical power units found with
the multichannel equipment are the PU-618, PU-625/G, PU-626/G, and
PU-628/G. Figure 1-36 shows a transporter truck towing such a power
unit.
PART C - MOBILE SUBSCRIBER EQUIPMENT
The tactical communications world is ever changing.
Currently, the
U.S. Army is evolving from the ATACS communications equipment
discussed in parts A and B, to a more modern system of Mobile
Subscribers Equipment. The Army purchased this equipment to meet the
needs of the modern battlefield. MSE is largely an automatic network
that provides mobile, highly decentralized communications from the
corps level down.

MSE Systems.
The MSE system uses branching layers of equipment that process a few
central areas into a network capable of providing communications to
thousands of subscribers.
The System Control Center (SCC) is the
central point for controlling the MSE system.
The backbone of the
system is the Node Centers (NCs).
These NCs interconnect and
communicate with each other.
Each NC covers a certain geographical
area.
They are mobile equipment stations that deploy with the
division. Each NC has extension nodes branching from it. Figure 1-
37 illustrates the branching structure of the MSE system.
These extensions, either Large Extension Nodes (LENs) or Small
Extension
Nodes
(SENs),
provide
voice,
data,
and
communications to the division command posts (CPs), and provide
automatic switching to all MSE subscribers.
To provide access to
mobile subscribers, Radio Access Units (RAUs) link them to the
LENs/SENs.
RAUs are radio transmission sites that receive traffic and routes it
to its proper destination.
RAUs slightly overlap one another to
provide continuous coverage for subscribers.
Thus a subscriber
moving
from
one
RAU
area
to
another
need
not
reestablish
communications. His mobile subscriber radiotelephone terminal (MSRT)
automatically searches for the nearest RAU signal, and shift
communications to that RAU.
