Fleming sat on the committee that selected the targets for the T-Force unit, and listed them in the "Black Books" that were issued to the unit's officers. The infantry component of T-Force was in part made up of the 5th Battalion, King's Regiment, which supported the Second Army. It was responsible for securing targets of interest for the British military, including nuclear laboratories, gas research centres and individual rocket scientists. The unit's most notable discoveries came during the advance on the German port of Kiel, in the research centre for German engines used in the V-2 rocket, Messerschmitt Me 163 fighters and high-speed U-boats. Fleming would later use elements of the activities of T-Force in his writing, particularly in his 1955 Bond novel "Moonraker".
