An Army paratrooper was killed in Alaska after his vehicle rolled over Friday, the latest in a series of accidents that has killed or injured more than 50 troops and cadets since April.

Spc. Marquise Elliott, 25, crashed the armored Humvee he was driving at 3 p.m. on June 14 in Alaska’s Yukon Training Area. Elliott was transferred to Fairbanks Memorial Hospital and pronounced dead at 3:23 p.m. Another soldier suffered injuries to his “lower extremities” and was treated by medics at the scene. Both were members of the Alaska-based 2nd Battalion, 377th Parachute Artillery Regiment.
