MI6, the British foreign intelligence agency, doesn't have a covert action arm. Which is not to say that our government hasn't done any fuckery with other countries' politics (we're also a former imperial power) but it does lessen the temptation and the capability.
“ SIS activities included a range of covert political actions, including the overthrow of Mohammed Mossadeq in Iran in the 1953 Iranian coup d'état (in collaboration with the US Central Intelligence Agency).[85]”
“ During the Soviet–Afghan War, SIS supported the Islamic resistance group commanded by Ahmad Shah Massoud and he became a key ally in the fight against the Soviets. An annual mission of two SIS officers, as well as military instructors, were sent to Massoud and his fighters. Through them, weapons and supplies, radios and vital intelligence on Soviet battle plans were all sent to the Afghan resistance. SIS also helped to retrieve crashed Soviet helicopters from Afghanistan.[90]/
“Some of SIS's actions since the 2000s have attracted significant controversy, such as its alleged complicity in acts of torture and extraordinary rendition.[10][11]”
“ The stated priority roles of SIS are counter-terrorism, counter-proliferation, providing intelligence in support of cyber security, and supporting stability overseas to disrupt terrorism and other criminal activities.[8]”
“ In March 2016, it was reported that MI6 had been involved in the Libyan Civil War since January of that year, having been escorted by the SAS to meet with Libyan officials to discuss the supplying of weapons and training for the Syrian Army and the militias fighting against ISIS.[113] In April 2016, it was revealed that MI6 teams with members of the Special Reconnaissance Regiment seconded to them had been deployed to Yemen to train Yemeni forces fighting AQAP, as well as identifying targets for drone strikes.[114] In November 2016, The Independent reported that MI6, MI5 and GCHQ supplied the SAS and other British special forces a list of 200 British jihadists to kill or capture before they attempt to return to the UK. The jihadists are senior members of ISIS who pose a direct threat to the UK. Sources said SAS soldiers have been told that the mission could be the most important in the regiment's 75-year history.[115]”
“ E Squadron is the sole paramilitary group within SIS.[132] There is limited information about the squadron in the public domain, and it was not until the 1990s that it was officially recognised by the British government. Although the Government has declassified some information about the squadron, details about its operations generally remain secret. Before the 1990s, the group was known mainly by pseudonym The Increment.[133]
Out of all the British special forces units, E Squadron is a branch of the wider UKSF and many of its combatants are hand-picked to work with the SIS. The group is available for undertaking any task at the requirement of the both UKSF Directorate and SIS. It is manned by operators from the Special Air Service (SAS), Special Boat Service (SBS) and the Special Reconnaissance Regiment (SRR).[133]”
They definitely have guns, and aren’t afraid to use them. And they’re fundamentally covert.
