Veterans who served in Iraq and Afghanistan allege exposure to smoke from open-air burn pits where military contractor disposed of waste, including batteries and tires, caused serious, sometimes fatal, illnesses. Further, the contractor supplied harmful, insufficiently potable drinking water. Fourth Circuit: Can’t sue the contractor over that. The record, developed by means of a “herculean” discovery process, shows the military had control over the contractor’s operations, and we can’t second-guess the military’s decisions in a war zone.
