Times Insider delivers behind-the-scenes insights into how news, features and opinion come together at The New York Times.

A retired Marine sergeant on what it’s like to kill for the first time, a foreign correspondent on his kidnapping by the Taliban, a veteran’s parents on the suicide of their son — all of these deeply personal firsthand accounts from America’s military conflicts in the Middle East originated on At War, a somewhat rogue operation of a blog that The Times ran from 2009 to 2016.

On March 20, the 15th anniversary of the invasion of Iraq, At War officially returns. Now part of The New York Times Magazine, the new iteration will continue to tell stories of the American war experience while expanding its coverage to global conflicts and their outcomes, including the continuing refugee crises. The first essay looks back at March 20, 2003, through the eyes of a veteran Marine lieutenant who led a platoon of six tanks into Baghdad.
