US military rules under review after soldiers surrendered pistol to Mexican troops on American soil

A senior defense official says the Pentagon is reviewing how U.S. soldiers responded during an incident this month in which Mexican troops detained and disarmed Americans on Texas soil.

The standoff between two U.S. soldiers and as many as six Mexican military officials on April 13 is believed to be the first of its kind, according to the senior defense official from Northern Command, or NORTHCOM. "This is the first incident that we're aware of that the two militaries came together," the official told the Washington Examiner.

Two Army soldiers from Washington state were sitting in an unmarked Customs and Border Protection vehicle south of the U.S. barrier but north of the international boundary near Clint, Texas, when Mexican troops moved in on them.

The Mexican soldiers, each carrying FX-05 Xiuhcoatl rifles, detained, disarmed, and questioned the U.S. troops. One soldier's Beretta M9 service pistol was taken from him and temporarily confiscated.
