Brats in Battalions is the second studio album by the American punk rock band the Adolescents, released in August 1987 on SOS Records, the band's independent record label. It followed a reunion of the band after a five-year breakup, and subsequent lineup changes which saw drummer Casey Royer and original guitarist Frank Agnew replaced, respectively, by Sandy Hanson of the Mechanics and by Agnew's younger brother, Alfie Agnew. Brats in Battalions explores several styles of punk rock and features new recordings of all three songs from 1981's Welcome to Reality EP, as well as cover versions of the traditional folk song "The House of the Rising Sun" and the Stooges' "I Got a Right". Singer Tony Brandenburg (here using the stage name Tony Montana) left the band after this album, and the Adolescents recorded one more album without him, 1988's Balboa Fun*Zone, before breaking up for another 12 years. The Adolescents had broken up in August 1981, two months before the release of their Welcome to Reality EP. Guitarist Rikk Agnew, who had left the band earlier that year after the release of their debut album, Adolescents, joined the gothic rock band Christian Death, playing on their 1982 album Only Theatre of Pain, and released a solo album, All by Myself (1982). Singer Tony Brandenburg formed a new band, the Abandoned, who released one album, Killed by Faith (1985). Bassist Steve Soto and guitarist Frank Agnew joined Los Angeles punk band Legal Weapon, playing on their 1982 album Death of Innocence; Agnew remained with them for Your Weapon, released later that year, then moved on to Hvy Drt, playing on their 1985 Hvy Drt EP. Drummer Casey Royer, meanwhile, started D.I., taking on the role of singer, and was joined by Rikk Agnew for the D.I. EP (1983). Agnew then brought in his younger brother, Alfie Agnew, and the two remained in D.I. until 1987, playing on the albums Ancient Artifacts (1985) and Horse Bites Dog Cries (1986), and the Team Goon EP (1987). The Adolescents lineup of Brandenburg (now using the stage name Tony Montana), Soto, Royer, and Rikk and Frank Agnew played a reunion show in April 1986 at Fender's Ballroom in Long Beach, California which led to the band re-forming. They played more shows and began working on material for a new album, recording a demo of two new songs, "The Liar" and "Peasant Song". Frank Agnew left the band after a few months, however, and was replaced by his younger brother Alfie, then Royer left the group that August. "Casey wanted to keep D.I. going, and I lost interest", said Frank. "I think that when Casey left, the band lost a major part of its sound", reflected Brandenburg in 1989. "Casey always played this kinda surf beat. On top of that, he was a major part of the vocal attack. When Casey left, the band...changed". Royer's replacement was Sandy Hanson, formerly of the Mechanics, a fellow Fullerton, California band that had been a key influence on the Adolescents. The new Adolescents lineup entered Advanced Media Systems in Orange, California in the summer of 1986 to record their new album, co-produced by the band members and Gordon R. Cox. In addition to "The Liar" and "Peasant Song", they recorded five new songs: "Brats in Battalions", "I Love You", "Skate Babylon", "Marching with the Reich", and "She Wolf". They also rewrote one of the band's early songs, "Do the Eddie"—a joke song from a July 1980 demo tape written about Eddie Joseph of the band Eddie and the Subtitles, who had engineered the demo and subsequently became the band's manager—as "Do the Freddy". The remainder of the album consisted of new recordings of all three songs from the Adolescents' 1981 EP Welcome to Reality ("Welcome to Reality", "Losing Battle", and "Things Start Moving"), and cover versions of the traditional folk song "The House of the Rising Sun" and the Stooges' "I Got a Right". Mike McKnight played additional guitar parts on "The Liar"; he would go on to join Soto and Hanson in their post-Adolescents band Joyride during the early 1990s, and join the re-formed Adolescents from 2008–2013, playing on the albums The Fastest Kid Alive (2011) and Presumed Insolent (2013). Brandenburg came up with the concept for Brats in Battalions' cover art, a photograph of young boys holding various firearms.
