A 26-year-old British army soldier died at the scene after collapsing during a training exercise on a North Yorkshire moor, police said.
A North Yorkshire Police spokesman said:
Officers were called just before 9am on Wednesday 28 August 2013, following a report that a 26-year-old man, serving in the military, had collapsed at Barden Moor, Leyburn.
Sadly, despite the efforts of paramedics, he was pronounced dead at the scene.
We are not yet in a position to release his name. His family have been informed.
Officers are working with the Army to establish the full circumstances surrounding the death, which is not suspicious, so that a file can be prepared on behalf of the coroner.
