Rehearsals. Rehearsals familiarize unit members with the mission plan and visualize the expected action. Depending on
the level and repetition of rehearsal, unit members can develop a thorough familiarity with the sequence of events that
will be executed. A rehearsal should be conducted as a scripted event that lays out the operational plan in a sequence of
overlapping events. Contingencies and complications can be injected to assess unit member reactions and to practice
alternate plans.
Full dress rehearsals provide the most detailed understanding of the operation and involve all unit members executing
their expected tasks flowing through the expected timeline of the event. A full dress rehearsal is a military field exercise;
a training event preparing for the real event at a similar location layout. A Reduced Force Rehearsal involves only key
leadership of subordinates and operational units. Terrain model rehearsals, also known as ROC drills or sandbox drills, use
miniature depictions of the operational area. Terrain model rehearsals are historically the most commonly used method for
rehearsal of military operations. Map rehearsals can be used virtually anywhere using actual maps, imagery or sketches
of operational areas.
A communications rehearsal, also known as a COMMEX, is a combination of testing communications systems as well as
unit members running through the sequence of events through radio calls. For the communications equipment tests, using
the same equipment, same frequencies, and same distances specified in the operational plan will provide the unit with
the best insight into whether their equipment will function properly. If possible, line-of-sight obstacles such as buildings
or terrain should be interposed between radios to exactly replicate conditions at the target. Casualty response specific
execution checklist calls must be integrated into the overall unit EXCHECK. Example calls may be CCP established,
evacuation asset in place/on station, casualty HLZ (CEP or AXP) established, and most importantly the radio notification
call for a casualty report. Contingency or deviation calls may be required for mass casualty situations, accidents/incidents
involving aircraft or vehicles, and changes from primary to alternate aircraft/vehicles, key locations, evacuation assets, or
receiving medical facilities.
