Final answer:
Under Inter-Service Joint Instructions, if Navy is the LEAD SERVICE and the Join instruction has not been revised or cancelled by its 10-year anniversary date, it will continue to be in effect until it is revised or cancelled by the Navy.
Step-by-step explanation:
Under Inter-Service Joint Instructions, if the Navy is the LEAD SERVICE and the Joint instruction has not been revised or cancelled by its 10-year anniversary date, it will continue to be in effect until it is revised or cancelled by the Navy.
Inter-Service Joint Instructions are agreements and procedures that govern the operations and coordination between different branches of the military. The lead service is responsible for establishing and maintaining these instructions. If the Navy is the lead service for a particular instruction and it remains unchanged after 10 years, it will still be valid until the Navy makes any revisions or cancellations.
For example, if the Navy is the lead service for a joint instruction on naval operations and the instruction has not been revised or cancelled by its 10-year anniversary, it will still apply to all branches of the military until the Navy decides to make any changes.
