the two main belligerents in the sudanese civil war are the rapid support forces (rsf) and the sudanese armed forces (saf) the rsf was basically a special unit of the saf until they broke off and became their own splinter group. think of it like the us marines breaking off and starting a war with the us army generally the rsf are being backed by the uae and its african allies while the saf are backed by russia and iran.  western powers are officially staying out of it besides a few token sanctions, but remaining relatively silent while one of their greatest allies and arms purchasers, the uae, is involved, speaks for it self
