The MFI-9B MiniCOIN's flew more than 300 combat missions in Biafra attacking Nigerian Air Force facilities and airplanes, that were used to harass and terrorize the civilian population. The actual effectiveness is not known, since the Nigerian casualty reports are probably too low while the MFI-9B pilotes estimates are too high. Although the destruction of only one NAF MIG 17F can be positively confirmed, that single MIG 17 (serial, NAF 620) probably cost the NAF more money than the entire MFI-9B fleet cost the Biafran government. It is clear that the NAF escaped more serious damage in many BAF
attacks because of the lack of experience of BAF pilots (including the von Rosen group) and the limited arsenal of the MiniCOIN. The effectivness of the mini-COIN´s was mucha psychological one, irritating the Nigerian Air Force and forcing them to be on the alert for attacks. Together with the confirmed destroyed MiG-17 there were serveral MiG´s and Il-28´s together with NAF facilities reported damaged during the raids.
