JACKSONVILLE, ONSLOW COUNTY -

Camp Lejeune has released the name of a Marine who died after a fitness test at Camp Johnson Friday morning.

Lt. Col. Andrew Reed, 39, had just moved on base from Northern Virginia to take his seat as the new commanding officer of Logistics Operations School.

But Reed collapsed during the run portion of a semi-annual physical fitness test at about 7:40 a.m. Friday at Camp Johnson, which is a satellite base of Camp Lejeune, officials said.

"We had emergency medical responders get on the scene shortly after he collapsed and there were attempts by those who were standing around to revive him," said Camp Lejeune Director of Public Affairs Nat Fahy.

Lt. Col. Reed was transported to Onslow Memorial Hospital, where he was pronounced dead about an hour after he collapsed. It appeared Reed died from a massive heart attack, said Fahy.

"This happened so unexpectedly and so tragically and our thoughts and prayers go out to the families at this time," Fahy told NewsChannel 12.

Funeral arrangements are pending.

The Marine Corps tries to reduce the risk of medical emergencies during physical fitness tests by scheduling them early in the morning before the sun gets too hot and the humidity increases.

"The base has a system of flag warnings-- the color flag warnings," Fahy explained. "If it's green, it's a permissive environment. If it's yellow, it's cautionary. If it's red, it's even more cautionary, and if it's black, they limit down to the bare minimum of physical activity."
