must be assigned. For nets with outlying stations, beyond the normal operating range, retransmission
units must be established, and the physical support planned for. All stations must know their operating
frequencies and be able to contact outside stations should the need arise. Additionally, planning for
communications during a radio blackout should be done.
(4) CSS units are no less vulnerable to enemy electronic warfare than artillery or air defense
units. The signal officer should plan, with all staff section, how to respond to enemy jamming and loss
of voice communications. Establishing messenger service may be the only external means a unit has
after enemy jamming begins.
b. Wire communications planning considerations. Table 3-2 lists planning considerations when
using wire. Some key considerations are discussed below. Additional information in Chapter 4 of FM
24-16, Communications-Electronics Operations Orders, Records and Reports, and Chapters 3, 7, and 9
of TC 24-20, Tactical Wire and Cable Techniques.
Table 3-2. Wire Planning Considerations
(1) Wire lines provide effective communications that are usually unaffected by poor weather
or enemy jamming; however, they are very susceptible to damage. If time permits, the signal officer
should ensure aerial wire lines are run. This takes extra time, but reduces the chances of vehicular
(2) Wire lines are often laid along the MSR. The wire lines must not be laid too close to the
road, and they should be minimally exposed to vehicles. Not enough slack will cause a wire line to
suspend high enough to be snagged by a passing truck; leave plenty of slack to allow the wire line to
(3) All wire lines must be planned for and depicted on the unit's line route map.
Additionally, the wire team must be well trained in troubleshooting and splicing techniques.
