"Army of Me" is a song recorded by American singer-songwriter Christina Aguilera for her seventh studio album, "Lotus" (2012). It was co-written by Aguilera with Jamie Hartman, David Glass and Phil Bentley, with production done by Hartman and Tracklacers. Described by Aguilera as part two to her 2003 single "Fighter", she decided to record the song so that her newer, younger fans would have an empowering song to listen in case they were unfamiliar with her previous work. The song combines dance-pop and Eurodance genres; its instrumentation incorporates drum beats and rock guitars. "Army of Me" garnered mixed reviews from music critics. Many praised Aguilera's strong delivery of the song's message and branded it a potential single, while others criticized it for being too similar to "Fighter". Upon the release of "Lotus", the song debuted on the South Korea international singles chart at number 103 with digital download sales of 2,689. Aguilera has performed the song at the 40th American Music Awards in the United States.
