"2,000 armed youths." Hmm. I seriously doubt all "2,000" of them were armed with actual, working guns with bullets. Given the remote location of Bor, I seriously doubt the rebel leaders could coordinate to get 2,000 daily bowls of rice to feed them, much less 2,000 bullets.
In addition to your lack of knowledge of tiltrotor technology, you have now demonstrated your ignorance of knowledge of the political situation in South Sudan. One of the basic underlying problems is that 'bullets and arms' are overwhelmingly available, whereas 'rice, water, and other life sustaining amenities' are not. That is the problem...
