On April 14, a National Guardsman assigned to Operation Lone Star "discharged a weapon in a border-related incident," the Texas Military Department said.
An assessment of the Pentagon's efforts to disrupt drug traffickers comes as the number of U.S. overdoses involving synthetic opioids continues to climb.
Authorities said the Guardsman turned around at a Border Patrol checkpoint and fled, leading to a 15-mile chase at speeds of more than 100 miles per hour.
