British Services Security Organisation (Germany)

The British Services Security Organisation was a MI5 sponsored organisation supporting British senior commanders with multi-source security intelligence directed initially at counter espionage, but near the end of its operational life much involved in counter terrorism support.
BSSO was the successor of a post-war security intelligence unit to the British Forces Security Unit in March 1954. In 1961 BSSO was refocused on supporting British forces chiefs in Germany rather than collecting at the behest of London.
The first head of BSSO was Major-General Denis Price, CB, CBE.
BSSO had an important role in maintaining liaison with German Federal and State Security Services ; in performing this role BSSO's office in Cologne was vital.
Much of the detail of BSSO operations and relationships especially in the latter stages of its life are still classified
