LAS VEGAS — The Nevada National Guard has identified a soldier who was killed during a training accident Tuesday night as 51-year-old Guard Staff Sgt. David W. Gallagher of Las Vegas.

Gallagher was killed and three other soldiers were injured when a tank rolled over at Fort Irwin, California, where the soldiers’ Idaho-based brigade is undergoing a month-long training.

Lt. Col. Mickey Kirschenbaum says Gallagher was an armor crewman who joined the military in 1988 and enlisted in the Nevada Army Guard in 2009.

The three other soldiers who were injured were released from the hospital.

The cause of the accident is under investigation.

“We are saddened by the events that happened to our soldiers at Fort Irwin,” Nevada Army National Guard Chief of Staff Col. Cory Schulz said. “Sgt Gallagher was a motivated, dedicated non-commissioned officer who will be greatly missed. As soldiers we strive every day to live up to the example set by him. Again, our thoughts go out to his family and loved ones.”
