A security forces airman assigned to Osan Air Base, South Korea, collapsed during a ruck march July 21 and was rushed to the hospital with a body temperature of 108 degrees.

Airman 1st Class Mikhahael Ragay, a member of the 51st Security Forces Squadron at Osan is listed in critical condition.

“A member of the 51st SFS passed out during the ruck march and was taken to the emergency room,” confirmed Staff Sgt. Tinese Jackson, a 51st Fighter Wing spokeswoman, to Stars and Stripes. “The Airman is currently being treated and recovering at an off-base hospital in the Republic of Korea,” she added.

A GoFundMe page has emerged with a $10,000 goal of supporting the family of Airman 1st Class Mikhahael Ragay. The fundraiser states Ragay “is currently in critical condition in a comatose state.”

The Korean Peninsula and Japan have recently endured a scorching heatwave, with temperatures reaching as high as 107 degrees.
