The U.S. Marine Corps released the identities on Sunday of four service members who died when their aircraft crashed during a NATO exercise in the Arctic Circle on Friday. 

The four fallen Marines, who were assigned to the 2nd Marine Air Wing, are Capt. Matthew J. Tomkiewicz of Indiana, Capt. Ross A. Reynolds of Massachusetts, Gunnery Sgt. James W. Speedy of Ohio, and Cpl. Jacob M. Moore of Kentucky. 

Their aircraft, an MV-22B Osprey, crashed during the Cold Response drill, which involves 220 aircraft, 30,000 troops, and 50 vessels from 27 countries.

The Marines were reported missing around 6:30 p.m. on Friday evening during a training mission in northern Norway. Rescue helicopters eventually spotted the wreckage, but couldn't immediately get to the crash site due to bad weather.

Their remains were recovered by a Royal Norwegian Air Force rescue helicopter around 7:00 p.m. local time on Sunday evening, the Norwegian Armed Forces said. 

"We will continue to execute the mission while keeping these Marines and their service on the forefront of our minds. We will never allow these Marines’ sacrifice to go unnoticed or unappreciated," Maj. Gen. Michael Cederholm, the commanding general of 2d Marine Aircraft Wing, said in a statement. "Keep these Marines and their loved ones in your thoughts and prayers." 

The cause of the crash is currently under investigation. The Cold Response drill was announced eight months ago and is not linked to Russia's invasion of Ukraine, NATO said.
