The area where the crash happened Tuesday night was under a fog advisory. It was still extremely foggy today morning, Eglin public affairs specialist Sara Vidoni said.
Base officials said the Marines are part of a Camp Lejeune-based special operations group and the soldiers were from a Hammond, Louisiana-based National Guard unit.
The helicopter was reported missing around 8:30 p.M. Tuesday and search and rescue crews found debris from the crash around 2 a.M. Wednesday, Eglin spokesman Andy Bourland said.
Bourland said the Army helicopter took off from a nearby airport in Destin and joined other aircraft in the routine training exercise.
The UH-60 Black Hawk helicopter went down on a remote swath of beach between Pensacola and Destin. The beach is owned by the military and is used for test missions.
The training area includes 30 kilometers of pristine beachfront that has been under the control of the military since before World War II. Military police keep a close watch on the area and have been known to run off private vendors who rent jet skis or paddle boards without permission.
The military sometimes drops trainees over the water using boats or helicopters and the trainees must make their way onshore.
