The current bunfight inside the Sudan is between the Rapid Support Forces (RSF) a paramilitary force set up by Bashir in 2013 out of the Janjaweed militias who ran riot inside Darfur Since its birth, it has seen combat in Libya and Yemen. Interestingly the RSF has the support of the UAE and Wagner and on the other side of the table we have the Sudanese military.
Sudan has been in political turmoil after the ousting of Omar al-Bashir (who ruled Sudan from 1993 to 2019) in 2019 which saw him removed by a coup that year, followed by an attempt by his supporters in Sept 2021 and a successful one a month later in Oct which included the RSF
The military seeing that the RSF was a loose cannon set in motion a plan for it to be fully absorbed into the Sudanese military in Feb this year. Whilst the RSF publicly agreed to this, they started recruiting heavily paid for by goals mines they had captured in Darfur and started massing forces at strategic points around the country, on the 15th of April the RSF carried out a pre-emptive strike at Sudanese military bases across the country and here we are today.
Both sides of the bunfight are heavily armed, which includes aircraft and anti-aircraft weaponry, with reports that civilian aircraft have been fired upon (Saudi airliner on the 15th, a Indian one which saw 3 people killed)
The situation inside the Sudan has been on a downward spiral since Bashir was removed from power in 2019. Which explains the battle for hegemony which whoever wins, won't be the last
