Saw this post, and to be honest the UAE imported a lot of South Africans to work on these products. These South Africans are nearing retirement and will work on any project for the right price and many have decades of experience.
Most are ex Denel employees in their 40s and 50s and making much more than what they make in South Africa with a dying defense industry.
Quite a smart move on the part of the UAE in my opinion, and allows a country with under 10 million to fulfill some needs of armed forces. UAE will likely never be sanctioned so parts supply is a non issue for them to be honest.
