4174 SUBMARINE REPORTING
Specific submarine reporting requirements must be tailored to the scenario and clearly understood
by all parties prior to operations. Keeping the SOCA informed of contacts, search and engagement results,
intentions, and status is essential. Prompt contact, post-engagement, and periodic situation reports from
each submarine are key to the SOCA maintaining a master fused plot of operations, and the OTCs ability to
coordinate, allocate, or reassign assets as the operational situation evolves.
