Section 20

Section 20 is an elite military black ops counter-terrorism unit within the British government in the Secret Intelligence Service (MI6) that's responsible for covertly travelling around to globe to attack terrorist threats where they originate. Focusing on high-risk and top-priority targets, the unit is capable of moving from country to country anywhere in the world, sometimes covertly, sometimes with the agreement of the government. Section 20 operates as a highly sophisticated mobile intelligence unit.
