As figure 2-4 shows, the intelligence sections of the major subordinate elements operate in this net. The
surveillance detachment feeds information it obtains on enemy movements to division, where the
intelligence is analyzed and the necessary action is decided on.
(c) The division general purpose net (radio teletypewriter (RATT)) links the DISCOM
headquarters with the division CP and the major subordinate elements (Figure 2-5). This net provides
hard copy messages within the division and its AM radios increase the range of operation. Commanders
may use it at their discretion for fire and maneuver, combat support (CS), or combat service support
(CSS). An important point is that this net should be used as much as possible as an alternative to voice
messages, especially for lengthy reports.

(d) The division AM voice net (single sideband (SSB)) links the DISCOM to the division
CP and major subordinate elements in the division (Figure 2-6, page 2-6). This net is especially useful
when units are out of FM range. In addition, this net can take some of the command and control traffic
off the command/operations net (FM).
