Titled "Keep Us Safe," Underwood created the song specifically for ACM Presents: An All-Star Salute to the Troops, a two-hour special airing on CBS starting at 9pm ET/PT.

"When we were approached to be a part of the show, I was so excited to do something to honor our troops and because ACM Lifting Lives does such great work," Underwood said in a press release.

"I wanted to take the time to really think about what song I wanted to perform. I had a writing session scheduled with my co-writers and friends Hillary Lindsey, Luke Laird, and Shane McAnally, and I guess the show was weighing on my mind. I think we all left the session knowing the song was special because it basically wrote itself that day!"
