  NETWORK REHEARSAL
  D-12. The network rehearsal is less desirable because the personal interaction is not possible. The network
  rehearsal does have advantages, however. It can be conducted at any time, and it can verify a unit's
  communications capabilities. If used, the network rehearsal must focus on the critical actions in an operation.
  Lengthy transmissions should be avoided and alternate frequencies should be used to avoid compromising
  the unit and the operation. All participants must have reliable communications, OPORD, overlays, maps, and
  must understand the rehearsal sequence. The network rehearsal depends heavily on SOPs that establish
  procedures for network rehearsal execution.
  D-13. Network rehearsals can be executed over wide-area networks or local-area networks. Commanders and
  staffs execute network rehearsals by talking through critical portions of the operation over communications
  networks in a sequence the commander establishes. The organization rehearses only the critical parts of the
  operation. These rehearsals require all information systems needed to execute that portion of the operation.
  All participants require working information systems and a copy of the OPORD and overlays. Command
  posts can rehearse battle tracking during network rehearsals.
  D-14. The network rehearsal will probably be used more at the SHORAD battalion than other rehearsal
  techniques. The distances between batteries and the batteries supported unit planning and rehearsal
  responsibilities will consume the time necessary to conduct more time-intensive rehearsals at the battalion
  level. The Forward Area Air Defense C2 system will depend heavily on network rehearsals to verify
  communications systems are operational and let fire units acknowledge receipt of early warning information.
  SHORAD commanders should consider using the network rehearsal to augment other rehearsals or involve
  more participants.
