The NPA quickly spread alongside organizational work of the CPP. By 1972, it had established 735 barrio organizing committees and 60 barrio organizing committees, governing an estimated 400,000 people all over the country. The CPP used the NPA to establish barrio organizing and revolutionary committees, which served as instruments in administering the people's revolutionary government. Barrio organizing committees were established to lower land rent, eliminate usury, and ensure the "annihilation of enemy troops and the elimination of landlord despots, enemy spies, and such bad elements as cattle rustlers, extortionists, robbers, murderers, arsonists, and the like." Once established, barrio revolutionary committees replaced the BOC to formally establish the area as a stronghold of the revolutionary government. The NPA at the time had 72 squads of 800 regulars armed with weapons.
