One West Point cadet was killed, and 20 cadets and two soldier trainers were injured, on Thursday after a military vehicle overturned en route to a training exercise near the academy, a spokesman for the military academy said.

The cadet who was killed, Christopher J. Morgan, died at the scene of the accident, West Point officials said on Friday.

The truck, known as a light medium tactical vehicle, was transporting the cadets to a training area about eight miles from West Point’s main campus in upstate New York when it overturned at 6:45 a.m., a West Point spokesman, Lt. Col. Christopher Ophardt, said on Thursday.

The cause of the accident was unknown, Colonel Ophardt said.

The five-ton truck, which was being driven by a soldier trainer, overturned near Camp Natural Bridge, a summer training site of mountainous terrain. The cadets were in the middle of the annual summer program for rising seniors, which generally includes training in military field exercises.
