After the Argentine surrender, the group's 35 mm Oerlikon guns, abandoned and disabled by their operators, were captured by British forces. A total of 12 GDF-002 Argentine Army and 3 GDF-002 Argentine Air Force guns were captured and later shipped back to Britain in "Operation Skyguard", 5 Surviving Skyguard FC radars and the Argentine Air Force's Super Fledermaus FC radar were also shipped back to Britain. The Roland 2 fire unit was also sent back to Britain as a valuable prize. The GDF-002 guns were later refurbished by BMARC and used to form a Royal Auxiliary Air Force squadron at RAF Waddington. Four Skyguard radar units are employed by RAF Police to survey UK military flights over residential areas and to give warning of low-flying aircraft on sensitive facilities since 1993.
