Editing Special Operations Executive (section)

====Subsidiary branches====
Several subsidiary SOE stations were set up to manage operations that were too distant for London to control directly. 

SOE's operations in the Middle East and [[Balkans]] were controlled from a headquarters in [[Cairo]], which became notorious for poor security, infighting and conflicts with other agencies.{{Sfn|Foot|2004|pp=40–41}} It was eventually named, in April 1944, "Special Operations (Mediterranean)," or SO(M). Shortly after the [[Allied landings in North Africa]], a station code named "Massingham" was established near [[Algiers]] in late 1942, which operated into [[Southern France]]. Following the [[Allied invasion of Italy]], personnel from Massingham established forward stations in [[Brindisi]] and near [[Naples]].{{Sfn|Stafford|2011|pp=45–51}} A subsidiary headquarters, initially known as "Force 133," was later set up in [[Bari]] in [[Southern Italy]], under the Cairo headquarters, to control operations in the Balkans, including [[Axis occupation of Greece|Greece]],{{Sfn|Foot|2004|pp=40–41}} and [[Northern Italy]].

An SOE station, first called the "India Mission," and subsequently known as "GS I(k)," was set up in [[British India|India]] late in 1940. It subsequently moved to [[Sri Lanka|Ceylon]] so as to be closer to the headquarters of the Allied [[South East Asia Command]] and became known as "[[Force 136]]." 

A "Singapore Mission" was set up at the same time as the India Mission but was unable to overcome official opposition to its attempts to form resistance movements in [[British Malaya|Malaya]] before the [[Imperial Japanese Army|Japanese]] overran [[Battle of Singapore|Singapore]]. Force 136 took over its surviving staff and operations.

[[New York City]] also had a branch office, formally titled "[[British Security Coordination]]," and headed by Canadian businessman Sir [[William Stephenson]]. Their office, located at Room 3603, 630 [[Fifth Avenue]], [[Rockefeller Center]], coordinated the work of SOE, SIS, and MI5 with the American [[Federal Bureau of Investigation|FBI]] and the [[Office of Strategic Services]].
