A U.S. Marine Sergeant's Path to Journalism

In the fall of 2010, Reuters photographer Finbarr O’Reilly documented a firefight in Nabuk, Afghanistan involving U.S. Marine Sergeant Thomas J. Brennan (pictured). Six years later, the pair have partnered on an ambitious digital journalism initiative, The War Horse, and are writing Shooting Ghosts, a book that will be published in 2017 by Penguin’s Viking Books.
