a hit squad of the New People's Army in the Philippines
The Alex Boncayao Brigade (abbreviated as ABB; also known as the Sparrow Unit) was the urban assassination unit of the New People's Army, the armed wing of the Communist Party of the Philippines. Organized in 1984, the unit broke away from the New People's Army as a consequence of a split in ideology during the 1990s. In 1997, the Alex Boncayao Brigade allied itself with the Revolutionary Proletarian Army, the armed wing of the Revolutionary Workers' Party.
