Right, but now you're talking about using mercenaries to fight a civil war and vie for power over a sovereign nation. That's much higher stakes than a cobalt mine. Mercenaries in air forces have existed, but usually in the form of hiring pilots and maintenance crews to operate aircraft owned by one of the belligerent nations. This is what occurred in the Eritrean-Ethiopian war. These countries brought up former Soviet aircraft and munitions following the end of the cold war, and also hired ex-soviet pilots and ground crews to operate them. But this is a significant war with hundreds of thousands of combatants on both sides.
