Mi6

For its near century of existence, the Secret Intelligence Service (SIS) or MI6, known as the Firm, has developed one of the major tasks of data collection and intelligence operations around the globe. Always in defense of the British Empire and under the orders of His Majesty’s Government. From London to occupied Europe, from the distant colonies to the deserts of Arabia, from Berlin to the Soviet Union, the agents of the Firm became the dark defenders of the policy marked the British Crown. To know the role played by MI6 and its agents is one of the keys to understanding the political and military role of the British Empire in recent world history.
