The Canadian Army maintains a variety of forces on standby for employment within Canada. These forces are designed to support other government departments in a response to a domestic emergency situation and include reasonably well known organisations such as SAR (Search and Rescue). The 4th Canadian Division is based in Ontario and, as part of this overall force posture, maintains both Regular Army and Reserves on standby for employment in Nunavut. The Regular Army contribution to this emergency response capability is known as the Immediate Reaction Unit (IRU) with the Reserve component being called the Arctic Response Company Group (ARCG). Both the Regular and Reserve components of these standby forces, the IRU and ARCG respectively, will be provided the opportunity to conduct training in Nunavut during February 2018. This training will be conducted from the Canadian Armed Forces Arctic Training Centre (CAFATC) located in Resolute, NU. A small group will arrive approximately two weeks prior to the majority of the soldiers in order to conduct necessary equipment preparation and checks. This group will be housed at CAFATC until the arrival of the IRU on 4 February 2018. Working with 20-25 Rangers, the approximately 110 soldiers in the IRU will then conduct acclimatisation training in the vicinity of CAFATC prior to moving out on to the land. Movement will be by military Ski-Doo to a temporary tented camp location approximately seven kilometres east of the Hamlet of Resolute. Members of the local community will know this area as the location of the aircraft wreck from a crash in the late 1960s. From this camp smaller groups of soldiers numbering no more than 30 at a time will conduct patrols, on foot and ski-doo, further east reaching as far as the shore of Cornwallis Island. Similar sized groups may also return to CAFATC to conduct aerial patrols to the communities of Arctic Bay and Grise Fiord. These aerial patrols will use Twin Otter and DC-3 aircraft and will operate using permanent airfield locations only. Once in these communities, they will be primarily on foot to conduct short patrols in areas close to the communities. All patrols will be no more than 24 hours in duration before returning to the main camp at the crash site. After approximately four days, the ARCG will arrive at CAFATC. This is also a 110 member organisation and, once complete acclimatisation training, will relieve the IRU who will then return to CAFATC for travel south on 12 February 2018. ARCG training will be identical to that conducted by the IRU, including maintaining a camp in approximately the same location and the conduct of patrols. Rangers from 1 CRPG will at all times be present with soldiers while at the main camp site as well as when on patrols. Both the IRU and ARCG will also conduct a rifle and shot gun range in the vicinity of Resolute Bay, at a location used previously for this purpose. The ARCG will return to the south on 17 February with only a small 20 person group remaining until 20 February to ensure all necessary clean-up activities are completed. The overall aim of training is to ensure the ability of the IRU and ARCG to move, communicate and survive in the harsh conditions of a Nunavut winter thus ensuring their ability to provide support to local communities and other government departments in the event of a domestic emergency.
