When a member of your division has contact with a citizen of a hostile country, which of the following agencies should be informed?

The correct agency to be informed when a member of your division has contact with a citizen of a hostile country is the Naval Criminal Investigative Service (NCIS). NCIS is responsible for investigating and preventing crime within the Navy and Marine Corps, particularly those related to national security and counter-intelligence. Given the sensitive nature of interactions with citizens from hostile countries, NCIS plays a vital role in assessing potential threats, safeguarding classified information, and ensuring the safety of military personnel.

The involvement of NCIS in this scenario is aligned with its mandate to address issues related to espionage and other threats that could arise from contacts with individuals from nations considered hostile. This ensures proper investigation and mitigates potential risks to national security.

The other agencies mentioned have distinct roles: the FBI focuses on domestic security and federal law enforcement, the Department of Homeland Security (DHS) primarily deals with issues related to immigration and border security, and the State Department is concerned with foreign affairs and diplomacy. While these entities have important functions, NCIS is specifically equipped to address situations involving military personnel and threats from hostile countries, making it the most appropriate agency to notify in this context.
