The division support command (DISCOM) must have adequate communications to keep abreast of
changing situations and requirements on the battlefield to perform its tactical sustainment mission. The
DISCOM relies on its organic communications assets and the division signal battalion for
communications support. The large number of units operating in the division support area (DSA) may
require support units to find alternate methods for communication. The length of transmissions and the
accuracy with which they are sent directly affect the support mission. Planners should consider using
couriers and wire communications as alternatives for doing the support mission. This lesson will first
discuss signal systems using the older Army Tactical Communications System (ATACS), followed by a
discussion of Mobile Subscriber Equipment (MSE).
