As in WW2 von Rosen apparently wasn't shy about putting his money and clanking brass balls where his mouth was. So to help out and prove the mini-COIN concept he bought (for his own money, and not saying anything about the intended purpose) those spare MFI-9 the Swedish air force had rejected. They were sent down to Gabon for kitting out and camouflage paint jobs (mixed by eye to match the jungle). Then with French help he got some 68mm rocket pods which where jury rigged onto the aircraft. The passenger seats where tossed out and replaced with an extra 80l fuel tank. All this extra weight meant the tiny aircraft could just about get off the ground with the flaps set just right. A pair of Swedish pilots, one with no previous military experience, where recruited to come down (on their vacation) and help fly the first few raids. The three Swedes were all given official positions in the Biafran air force, along with uniforms. They decline side-arms since trying to shoot their way out of anything that as puppy eyes couldn't sort out if they went down was quite hopeless. With starving Biafran children in mind and looking at the negligible size of their aircraft, kind militarized the MFI-9 were called Bifra babies (later when Biafran flags an ID numbers were painted on the latter were painted on the latter all began with BB).
All this done the three Swedes and a local talent (August Okpe, who'd go on to be the Biafran air force's main pilot in the war) carried out four raids against Nigeria, focusing mainly on the Nigerian air force. These attacks destroyed a number of aircraft, damaged even more (possibly six and four respectively), damaged vital infrastructure, and appears to have killed the chief of the Nigerian air force. minimize the risk of collateral damage, for the loss of none of the babies.
Then von Rosen remained as an advisor, while the Biafrans took over the flying and the other swedes went home.
