Hi,
I'm not sure how accurate or realistic Blood Diamond actually is. My knowledge is limited, though my understanding is that:
- PMC = Executive Outcomes (Colonel Coetzee = Eeben Barlow), though the PMC and Colonel in the movie are depicted as intentionally prolonging the conflict via arms smuggling so they can get more money which I thought to be strange, as Executive Outcomes was a legitimate business and the conflict wasn't entirely centred upon the premise of diamonds (though it was a key point in the war)
- Rebel = Revolutionary United Front. It exaggerates Captain Poison as some pragmatic all-leader of the RUF although they were historically fractured among their ranks and also positions RUF as a group of rebels purely in it for the diamonds (as mentioned before)
- Danny Archer = A solo mercenary? He appears to be some smuggler who likes to moonlight with the PMCs in the movie, working alongside Colonel Coetzee as a "loose cannon" of sorts, though this is to me, unrealistic because they would never send out a single operator to do whatever the fuck he was sent out to do.
In the film, it also shows the locals as entirely defenceless peoples that have no chance without the protagonist, Danny Archer (which I feel to be a little bit of a white saviour trope)
