Join the Army is the second album by American crossover thrash band Suicidal Tendencies. It was released in 1987 – four years after their self-titled debut album – and is one of the most well known albums for crossing over the genres of punk and thrash metal, known as crossover thrash, a genre that Suicidal Tendencies have been credited for creating. Join the Army is arguably one of Suicidal Tendencies' popular efforts, although it only reached No. 100 on the Billboard 200 chart. This was their first album with guitarist Rocky George and drummer R.J. Herrera, and their last recording with bassist Louiche Mayorga (although he did co-write songs on their next album How Will I Laugh Tomorrow When I Can't Even Smile Today).
