An amphibious assault vehicle with 15 Marines inside burst into flames during a training exercise at Camp Pendleton, California on Wednesday, according to a source with knowledge of the incident.
Although the vehicle was engulfed in flames, all of the Marines were able to escape.
However, the source, who spoke on condition of anonymity since they were not authorized to talk with reporters, said that at least three Marines were being taken by helicopter to a local hospital for burns and smoke inhalation.
The extent of their injuries is not yet known.
The training involved Charlie Co., 1st Battalion, 1st Marines, an infantry unit situated at the northern end of the base at Camp Horno. The unit was carrying out a Combat Readiness Evaluation, the source added.
Camp Pendleton's media relations office confirmed there was an incident involving an AAV fire on base, but directed questions to 1st Marine Division.
"All Marines are currently being treated for injuries. Our thoughts and prayers are with the Marines and their families as they receive medical care. Officials are investigating the circumstances surrounding the incident at this time," 1st Marine Division spokesman 1st Lt. Paul Gainey said in a statement.
