The nature of the shadowy Rumbiak Brigade is hotly-disputed among different countries. Formed to fight colonialism around the world, it is know to operate in colonial areas such as Knootian Colombia (where some of its members have been arrested while smuggling arms) and in the part of Gallaga ruled by Iansisle.
The Brigade is named after Markus Rumbiak, a deceased political leader of Tanah Burung, and is dedicated to carrying on his struggle against colonialism.
The Brigade is believed to originate in Tanah Burung but also include citizens of other countries including Hell Bovines and The Weegies. Its source of arms is not known.
