For context, this isn't Hemedti's (leader of the Rapid Support Forces) first time of trying his hands at genocide successfully. He was one of the Janjaweed leaders enlisted by the Sudanese government for the early 2000s Darfuri genocide that led to murders of >300k locals at the hands of Arab militias.
That campaign helped Hemedti build up his profile, eventually become one of Sudan's power brokers (kinda like Prigozhin to Putin), amass eye-watering amounts of money (from gold mines yielding bullion that's laundered in Dubai), which in the latter case has been used to arm a substantial personal army.
The RSF were joined at the hip with the Sudanese Army until 2023 when they tried toppling the military to seize power and make Hemedti the national leader.
