The Revolutionary Cells - Animal Liberation Brigade (RCALB), known simply as Animal Liberation Brigade, is a name used by animal liberationists who advocate the use of terrorism and a diversity of tactics within the animal liberation movement, whether non-violent or not. As part of a praxis, the intention is to destroy oppressive institutions, describing an endgame for animal abusers. The Revolutionary Cells is not a group, but an example of a leaderless resistance, as a banner for autonomous, covert cells who carry out direct action, including political violence, similar to the Animal Rights Militia (ARM) or Justice Department.
