The U.S. Army issued a tweet ahead of Memorial Day weekend with a question for service members and veterans: "How has serving impacted you?"
Among the thousands of responses: harrowing tales of trauma, depression and sexual assault.
In a thread, an Army tweet that preceded the question featured a video by Pfc. Nathan Spencer, a scout with the Army's First Infantry Division.
In the video, Spencer says, "To serve something greater than myself. The Army's afforded me the opportunity to do just that, to give to others, to protect the ones I love, and to better myself as a man and a warrior."
