SOF = Special Operations Forces ... Green Berets, SEALs, etc. Who infiltrate in small numbers to call in air strikes and ambush local thugs.
OTL the whole Darfur crisis was a clash between two different climates, two different economies, two different races, two different religions and two different empires, both of which aim to dominate the planet.
Northern Sudan is largely dry desert that can barely support grazing - in the good years -. As climactic shifts brought moist and dry cycles, nomadic herders expanded or contracted their land claims, depending upon how many animals they could feed in a given year. Meanwhile, South Sudan (aka Darfur) gets more precipitation making it margin agricultural land.
ergo Northern Sudanese were largely nomadic herders while Darfur was dominated by small farmers. Over the centuries, farmers had granted herders seasonal access to grazing land, which North Sudanese wanted to claim as their territory permanently.
Racial tension was added to the mix because North Sudanese were arabs, while South Sudan citizens were mostly black-skinned Africans.
Religion further complicates the issue because North Sudanese are muslims who can call on wealthy Muslims to fund their defensive jihad, while South Sudanese were a mix of Christians and animists lacking militant traditions.
The two different Empires were China versus the western capitalists who dominate much of the rest of Africa. Chinese have been expanding into Africa for decades in search of farmland, minerals and oil. The Darfur Crisis was largely funded by Chinese interests trying to gain access to Sudanese oil.
Since Western oil companies had easy access to the vast petroleum reserves in the arabian peninsula, they had little interest in the smaller Sudanese oil reserves.
So the challenge is to convince a western oil company to contest Chinese claims to Sudanese oil and drag their respective governments into war. Religion, race, climate change, etc. Are just excuses to motivate the troops.
