A U.S. Marine died during a training exercise Wednesday at Camp Pendleton in Southern California, military officials said.
The Marine died of injuries sustained in a “tactical vehicle mishap” in the afternoon, the I Marine Expeditionary Force said in a statement.
He’s been identified Private First Class Tanner F. Rubio, 21, a native of Dixon, California.
He joined the Marine Corps in January 2025. Rubio was trained as an infantry rifleman and was assigned to 1st Battalion, 1st Marine Regiment, 1st Marine Division.
“The tragic loss of Pfc. Rubio is one felt across the 1st Marine Division,” said Maj. Gen. Thomas Savage, commanding general of the 1st Marine Division. “He will be sorely missed, but his honorable service to his country will not be forgotten. All of us at the Blue Diamond will keep him and his family in our thoughts and prayers.”
The cause of the incident was under investigation. Officials said the death was not related to Steel Knight, an annual, large-scale training exercise that began Monday on the base.
No further details were given.
The I Marine Expeditionary Force is the largest of the three Marine expeditionary forces and is located on the coast in San Diego County.
