Combined Operations Headquarters  was a department of the British War Office set up during Second World War to harass the Germans on the European continent by means of raids carried out by use of combined naval and army forces.
Admiral of the Fleet Roger Keyes was the first director, from 17 July 1940 to 27 October 1941, replaced first by Lord Louis Mountbatten and then Major General Robert Laycock (October 1943 – 1947). The main forces used by Combined Operations were the Commandos.
It comprised background staff whose job was to plan operations and to develop ideas and equipment to harass the enemy in any way possible. It also covered all those who worked with landing craft up to and including the landing ships that were used in the various amphibious operations.
The badge of Combined Operations was an eagle over a submachine gun over an anchor, reflecting the three service arms; the Royal Air Force, the British Army and the Royal Navy. In 1941 the title of Director of Combined Operations was changed to Adviser Combined Operations. In 1942 the title of Adviser Combined Operations was changed to Chief of Combined Operations.
