The majority of the ground phase of Exercise Northern Strike takes place on the 147,000 acres of the
Camp Grayling Joint Maneuver Training Center, the largest National Guard training center in the country. Camp Grayling is the largest open airspace for training east of the Mississippi River. 2016 saw the start of a major amphibious landing exercise being added to Northern Strike conducted by
United States Marine Corps Forces on
Lake Margrethe at Camp Grayling. In addition to inland water operations at Lake Margrethe, the exercise also utilizes the
Lake Huron littoral environment near
Alpena for coastal and maritime training scenarios, providing units with experience operating in Great Lakes shoreline conditions. Northern Strike 2017 saw more than 30
Joint Terminal Attack Controllers (JTACs) from around the globe take part. JTACs use specialized equipment to direct combat aircraft engaged in close air support and other offensive air operations from a forward observation position. Sometimes JTACs direct defensive air power for rescue evacuations. They are also called
Forward Air Controllers (FACs) and usually work with
Joint Fires Observers (JFOs) who assist with tracking and location identification. MQ-9 "Reapers" used in previous Northern Strike exercises had been flown from their home base. Greater emphasis has been put on medical and aeromedical procedures in recent Northern Strike. Combat Search and Rescue and the treatment of injured aircrew is regularly practiced during Northern Strike exercises. Patient resuscitation is a key skill practiced by personnel while attending Northern Strike. Northern Strike also incorporates
Cyberspace and Electromagnetic Activities (CEMA) training, where units practice operating in a contested electromagnetic environment. Camp Grayling's facilities are used to simulate electronic warfare scenarios, requiring personnel to develop skills in both disrupting adversary communications and maintaining mission effectiveness when their own systems are jammed. Northern Strike also serves as a venue for integrating
special operations forces (SOF) with conventional ground units.
Special Forces elements have participated in the exercise to refine conventional force–special operations forces (CF-SOF) interdependence, combining unconventional tactics with traditional ground maneuver and
close air support. ==International Participants==
