Well,as you know the Egyptian defence industry is not at the level of Israel or Turkey,but they have their own mindset of buying from various customers,which can give them an advantage as to the variety of systems and their potential (one might work where the other might fail)and the fact that they can avoid an embargo in case of a war. But as you know that also problematic,because of the logistics chaos and money required to maintain dozens of different systems,aircraft,vehicles,ships and ammo calibres.
