NOGruppe

Could you please provide a bit more context about NOGruppe? Is this a real organization or a fictional/ hypothetical one? If real, which country and time period does it pertain to, and are there reliable sources I should reference? If you want a fictional/alternative entry, I can draft a neutral, concise encyclopedia-style article that outlines its origins, aims, activities, and impact without claiming real-world status. Any specific details you’d like included?
