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.

Release and reception After completing the album, the Adolescents toured through much of the second half of 1986. Alfie Agnew then left the band at the end of the year to attend college and was replaced by Dan Colburn. The band toured for most of 1987, and
