When a radio operator indicates "In service to [location]," what code is used?

When a radio operator indicates "In service to [location]," the code used is 10-8. This code signifies that the operator is actively engaged in service at a specific location or is responding to a call for assistance. It is part of the ten-codes used to facilitate clear and concise communication among radio operators and personnel.

The use of 10-8 is essential in operational contexts as it helps to ensure that other team members and dispatchers understand that the operator is currently operational and may be unavailable for other communication, signifying their active engagement in mission-related duties.
