Section 20 is an elite military black ops counter-terrorism unit within the British government in the Secret Intelligence Service (MI6) that focuses on high-risk, top-priority targets. It operates as a highly sophisticated mobile intelligence unit. Section 20 is capable of moving from country to country anywhere in the world, sometimes covertly, sometimes with the agreement of the government.
