Strategy, meals and laundry: The monumental effort behind LA's firefight

Firefighters from across the North American continent have converged onto Los Angeles to fight the wildfires. From firefighters on the front lines to the cooks who feed thousands of responders everyday, fighting a wildfires is a monumental operation. The engines of that operation are incident command posts for each fire, which can host more than 5,000 responders who rotate through it. They are small cities, rapidly erected, and cook meals by the tens of thousands. Firefighters from Mexico, Canada and half-a-dozen states cycle through those centers in what's become an international effort to extinguish what may become the costliest wildfires in U.S. history.
