The purpose of the OTC is to provide authority and direction for actions the group is to take in the course of assigned operations and to communicate the information to higher authorities.
In port, under peaceful circumstances where there is no tactical situation, the senior officer present afloat (SOPA) assumes certain roles associated with the OTC.
The OTC is only empowered to direct the assigned forces for the specific purposes designated by the officer exercising operational command over the formation. The OTC may not reassign forces for another purpose.
