From a New York Times story by Dave Philipps headlined “An Army Veteran Says He Went Into ‘Combat Mode’ to Disarm the Gunman”:

Richard M. Fierro said he was at a table in Club Q with his wife, daughter and friends on Saturday, watching a drag show, when the sudden flash of gunfire ripped across the nightclub. His instincts from four combat deployments as an Army officer in Iraq and Afghanistan instantly kicked in. Fight back, he told himself.
