I think not. If you remember we have discussed something similar again. Their main problem right now is that they need more workers. They will certainly absorb many that are soldiers now. I don't know if they can absorb all of them though, but... they have operations in several other places, Sudan, Mali, Burkina fasho are some places. So... i guess they will manage overall.
Btw i don't like Russia's role in Sudan (i don't like the others too)
