New capabilities were trialled, such as scout dogs to aid in detection and tracking of enemy parties and the employment on Exercise Pitch Black 1990 of M113 Armoured Personnel Carriers from the Army's 2nd Cavalry Regiment to provide armoured mobility for the QRF. Both capabilities may be considered to have matured in recent years with the attachment of Security Police (SECPOL) Military Working Dog (MWD) teams to ADG patrols and the introduction into RAAF service of the Bushmaster Infantry Mobility Vehicles. In 1992 2AFDS became the first non-flying unit to be awarded the Duke of Gloucester Cup.
