'Disclaim' was a British Force 133 airborne liaison mission by the Special Operations Executive to parachute a party of two British and two Yugoslav personnel, under the command of Major Cavan Elliot, in a blind drop to the east of Sarajevo in German-occupied Yugoslavia in an effort to link with the forces of Colonel Draza Mihailovic’s Četnik royalist resistance (5 February 1942).

All four men were caught by Croat forces shortly after landing, and were handed over to the Germans.
