Internal Radio Nets. Single-channel radio communications is the primary means used to provide
command and control of an air defense battalion. A brief description of each of the radio nets follows.
a. The battalion command net (FM voice) is the principal command and operations net within
the battalion to command and control the unit in support of the division. Figure 2-1 shows this net in a
heavy division. The air defense batteries are responsive to the division's needs as information
concerning Threat aircraft is exchanged between higher and lower headquarters. The Army airspace
command and control (A2C2) element, at both the division tactical command post (CP) and division
main, interfaces between division headquarters and the air defense battalion to keep the division
commander informed. Figure 2-2 illustrates the command net for a light division. Note the fewer
number of air defense batteries in the light division. FM retransmission radios are deployed to relay to
distant stations and to overcome intervening terrain.

b. The battalion administrative/logistics net (FM voice) is used to coordinate combat service
support requirements. Figures 2-3 and 2-4, page 2-4, illustrate this net. The administrative/logistics net
is used to ensure maintenance and personnel needs are met to keep the air defense systems up. A good
net control station will keep close track on repair parts being sent to users so that multiple parts can be
delivered in a minimum number of trips.
