3000 missions seems a lot of operational missions for one crew! They'd be flying more than one a day, everyday, for the entire war. 'Sie flog ihren...' translates as 'they flew their....' and I wonder if it refers to the members of the unit rather than one crew.

Well the board says "They flew their 3000 enemy mission. Perhaps it means the combined total of each crew member combined?
Edit: Jagdwaffe - Luftwaffe Colours Aufklaerer vol.2 Luftwaffe Reconnaissance Aircraft and Units 1942-1945 pg 88 mentions that on august 1941 the Staffel was awarded for its 2500 mission.
