An MI6 officer is a member of the Secret Intelligence Service (SIS), commonly known as MI6, which is the United Kingdom's foreign intelligence service. Their primary role is to gather intelligence from outside the UK to help protect national security and support government decisions. Officers often work undercover and may be involved in various operations, including espionage and counter-terrorism. MI6 officers typically undergo rigorous training and must possess strong analytical, communication, and problem-solving skills. They often collaborate with other intelligence agencies, such as MI5 and GCHQ, to share information and enhance national security efforts.
