THE PENTAGON HAD been slowly dedicating more resources to killing fewer civilians in recent years, following a long drumbeat of damning investigations of civilian casualties by the press, nongovernmental organizations, government-supported think tanks, and even the U.S. military itself.

The Intercept spoke with five current and former Defense Department officials familiar with its Civilian Harm Mitigation and Response, or CHMR, efforts, who say that the Pentagon is in the process of eliminating or downsizing offices, programs, and positions focused on preventing civilian casualties during U.S. combat operations.
