I want to know the answer to the following question:
Which guerrilla group fought for Namibia's independence?
All the background I'm provided with is that "Outside the central-southern area of Namibia (known as the "Police Zone" since the German era and which contained the main towns, industries, mines and best arable land), the country was divided into "homelands", the version of South African bantustan applied to Namibia, although only a few were actually established because indigenous Namibians often did not cooperate.". Is that enough to answer the question?
