A 17-year-old National Guard soldier died after she collapsed during military training at Fort Jackson in South Carolina last weekend, a report said.
Alyssa Cahoon, who was a private with the Pennsylvania Army National Guard, suffered the unknown medical episode during a training exercise on Aug. 20, Fort Jackson officials told WLTX.
She was transported by Fort Jackson EMS to an off-base hospital, where she died on Thursday.
“We extend our deepest sympathies to the family members and teammates of the deceased soldier,” US Army Training Center and Fort Jackson Commander Brig. Gen. Patrick R. Michaelis said in a statement.
“We are providing every comfort and assistance that we can to all involved.”
Cahoon was training with Fort Jackson’s 1st Battalion 34th Regiment this summer with her twin sister, Brianna Cahoon, according to a Facebook post from the battalion.
The twins were featured in a July 16 post that included a video of their rifle training.
An investigation into the cause of the death is being conducted, army officials said.
