The army said the cause of the crash was under investigation and more details would be released when they became available.
The crash is the second accident involving military helicopters in Alaska this year.
In February, two soldiers were injured when an Apache helicopter rolled after taking off from Talkeetna. It was one of four travelling to Joint Base Elmendorf-Richardson in Anchorage from Fort Wainwright.
In March, nine soldiers were killed when two US Army Black Hawk medical evacuation helicopters crashed during a routine night-time training exercise about 48 kilometres northeast of Fort Campbell, Kentucky.
Healy is located about 16 kilometres north of Denali National Park and Preserve, or about 402km north of Anchorage.
Healy is a community of about 1000 people on the Parks Highway in Alaska’s interior. It is a popular place for people to spend the night while visiting the nearby park, which is home to Denali, North America’s highest mountain.
Healy is also the town closest to the former abandoned bus popularised by the book Into the Wild and the movie of the same name. The bus was removed and taken to Fairbanks in 2020.
