i. In MSE, all terminal equipment is user-owned, installed and operated. The CSS signal
officer will play a critical role in assisting the MSE network managers at division (personnel from the
division signal battalion) in managing the network. The signal officer must ensure that:
(1) Users are trained in operating and installing all terminal equipment connected to the MSE
network.
(2) The network is fulfilling customer needs.
(3) Proper coordination is made before unit CPs move.
(4) COMSEC keys and frequencies are distributed.
(5) Subscriber problems are accurately identified.
(6) Troubleshooting is a coordinated effort between the signal officer and MSE network
managers.
4. Summary. In this lesson, you learned about the various signal systems that support combat service
support units.
a. The DSCOM operates in several external and internal radio nets.
(1) The external nets (division) that the DISCOM operates in are the command operations
net (FM), the intelligence net (FM), the general purpose net (RATT), the AM voice net, the rear battle
net (FM), and the rear battle net (AM).
(2) The internal nets that the DISCOM operates in are the command rear battle/operations
net (AM), the logistics operations net (AM), the medical command/operations net (FM), the medical net
(HF), the materiel management net (FM), the FSB command/operations net (FM), and the MSB
command/operations (FM).
b. DISCOM units (DMMC, FSBs, and MSB) access the MSE network through the SENS. The
DISCOM headquarters access the network through the LENS. Mobile subscribes enter through their
user-owned and operated MSRTs.
