A Mississippi Army National Guard soldier was killed and three others were injured Monday night at the National Training Center in Fort Irwin, Calif.

The deceased soldier was assigned to the Senatobia-based 2d Battalion, 198th Armored Regiment and was among four 2-198 AR soldiers conducting combat maneuver operations in a M1A2 SEPv2 Abrams Main Battle Tank, according to a press release. The vehicle was involved in a rollover incident.

The three injured soldiers were transferred by military helicopter to the Loma Linda University Medical Center in Loma Linda, Calif. Two were released and one was in stable condition Tuesday evening, officials said. All next of kin have been notified.

The 2-198 AR is a subordinate battalion within the Tupelo-based 155th Armored Brigade Combat Team and has paused operations to review safety procedures.

“Our thoughts and prayers are with our fallen soldier’s family, friends, and fellow 2-198 AR soldiers,” said Maj. Gen. Janson D. Boyles, the adjutant general of Mississippi. “The safety and security of our soldiers and airmen is paramount and we are working diligently to prevent any future incidents.

The incident occurred while the 155th Armored Brigade Combat Team soldiers, headquartered in Tupelo, participated in a large-scale, two-week training exercise at Fort Irwin, a remote facility 37 miles northeast of Barstow in the High Mojave Desert midway between San Bernardino and Las Vegas.

An earlier press release said soldiers would be participating with approximately 5,500 others in the U.S. Army’s Total Force Policy with active Army, Army National Guard and U.S. Army Reserve.

The rotation mimics a realistic training environment and cover potential adversaries such as guerrilla, insurgent, criminal and near-peer conventional forces.

The 155th Armored Brigade Combat Team, also known as the “Mississippi Rifles,” has battalion headquarters in Amory, McComb, Meridian, Monticello, Senatobia, Starkville and Kansas City, Kansas. It is the largest unit in the Mississippi National Guard with approximately 3,850 soldiers and is the sixth oldest infantry regiment in the U.S. Army.

This week soldiers focused on maneuvering tanks, said Kenneth Drylie, spokesman for the center. Drylie said it did not involve live-fire exercises.

The troops were doing an armored brigade combat team exercise, which emulates an overseas deployment to a war zone, Drylie said. Also participating in the training are National Guard members from California, Missouri, and members of the Air Force. He declined to comment further, saying the accident is under investigation.

Lt. Col. Christian Patterson, spokesman of the Mississippi National Guard, said the exercise has been suspended for the unit that the four members belonged to but the rest of the Mississippi Guard troops will still participate. He said no further details would be released to avoid compromising the investigation.

The center is one of the few places in the country with room for 10,000 troops to battle each other. It does 10 such training exercises a year with all branches of the military using the facility, Drylie said.

“It’s basically like a full deployment overseas except that it’s in the California desert,” Drylie said.
