Just for further context, the active frontline is mainly in the Kordofan region and the southern parts on the borders of South Sudan and Ethiopia.
Apart from the internal issues of the RSF, control of Kordofan is very important for economic reasons.
Kordofan and Darfur are two of the most important areas for the production of two main economic factors, gold and gum arabic. These two account for a significant portion of the Sudanese GDP, and since the RSF controlled the areas from the beginning of the war they used this to pay for weapons and soldiers.
As the Sudanese army advances into West Kordofan, there will be a major disruption to RSF funding, thus reducing their ability to expand their war, and possibly reducing the support available from Chad, South Sudan and Libya, as resources smuggled through these countries diminish.
Sudan produces 80% of the world's gum arabic, and since the beginning of the war, South Sudan has gone from producing almost nothing, to about 750 tons in 2024, all smuggled.
