The group, which includes retired Master Sgt. Caleb Green, retired Staff Sgt. Ron Henry, Sgt. Maj. Christal Rheams and Sgt. 1st Class Jason Hanna, will appear on Tuesday, Sept. 17, at 8 p.m. ET/PT and Wednesday, Sept. 18, also at 8 p.m. ET/PT.
The quartet made a splash in the audition round with its own arrangement of Katy Perry's 2016 hit single "Rise." Voices of Service is affiliated with the Virginia-based Center for American Military Music Opportunities (CAMMO), a group dedicated to creating music performance and career opportunities for military members and veterans.
That momentum has carried through the season, and they're now one of the show's top 10. Their semifinal performance of One Republic's "Choke" was the song that put them in the finals.
At the beginning of the season, the group talks about how music helped them cope with post-traumatic stress and how their mission is to bring the healing power of music to others dealing with the issue.
The group got the ball rolling with their version of Charlie Puth's "See You Again" (the Paul Walker tribute song from "Furious 7"), and the show's producers let them talk some more about their mission.
The show went heavy on the military angle when Voices of Service performed Gavin DeGraw's "Fire," backed by a choir that featured members from all five service branches.
