Military drills in San Diego address mistakes of the past

Thousands of marines stationed at bases from California to Arizona recently gathered at Camp Pendleton in southern California for the annual Steel Knight exercise. Instead of just military maneuvers, the troops used scenarios from past military mistakes, like the evacuation of Kabul in 2021. The drills took place in what the Marines call K-2 Combat Town, a simulated urban area. Andrew Dyer of KPBS reports.
