That sounds like a pretty kick-ass campaign concept, Chalk. I went through a big mercs in Africa phase a couple of years ago. Read a bunch of books about merc ops in the Congo, Sierra Leon, Angola, the Wonga Coup...
Really gritty stuff. It got rather depressing after a while. I had to stop.
Lot of MacGuffins in Africa. Diamonds in Sierra Leon, oil in Angola, Coltan (for cell phones) in Congo. After watching a doc on Netflix (can't remember the name), I briefly wanted to run a game where the mercs were protecting Mountain Gorillas from both sides in a civil war. "Guerillas in the Mist" never got past the conceptual phase.
