What additional manual elaborates on submarine responsibilities?

The correct answer focuses on the resource that specifically addresses submarine responsibilities within the Navy. COMNAVSUBFORINST 1306.1 (Series) is designed to provide detailed guidance and directives pertaining to submarine operations and the roles and responsibilities of personnel within that specific community. It serves as a vital reference for ensuring that submarine crews understand their unique tasks, training requirements, and operational protocols necessary for effective mission execution.

The other options, while important military manuals, do not specifically target submarine responsibilities in the way that COMNAVSUBFORINST 1306.1 does. OPNAVINST 1710.7 (Series) pertains to general Navy policies, RESPERSMAN M-1001.5 is related to personnel management and resourcing, and BUPERSINST 1001.39 (Series) focuses on administrative management within personnel. Thus, they lack the specific guidance related to submarine operations that the correct choice provides.
