A special variant known as the FV601D was developed for law enforcement agencies and internal security purposes; this model lacked a co-axial machine gun and had different lights and smoke dischargers. The FV601D was only adopted by the German Federal "Bundesgrenzschutz", which designated it "Geschützter Sonderwagen III". A Saladin was also offered with the same 30 mm RARDEN autocannon as found on the FV510 Warrior and FV721 Fox, but this model did not find favour with the British military or any export customers.
