FORT SHAFTER, Hawaii – A 25th Infantry Division soldier died Thursday morning from injuries sustained while training on Oahu, an Army statement said.

The death is under investigation, and the soldier’s name is not being released until the family is notified.

A spokesman for the 25th ID said no further information about the circumstances of the fatality was available.

The 25th ID is involved in the Lightning Forge exercise, which is slated to end on Sunday.

Soldiers in the large-scale training exercise are using blank ammunition and explosive simulators during daytime and nighttime training on the island’s East Range, Dillingham Army Airfield and Kahuku Training Area, the Army announced earlier this week.olson.wyatt@stripes.com Twitter: @WyattWOlson
