I said to you previously that there's a certain asymmetry in aviation assets. You just pointed out one thing: the turn radius of a MiG-21 versus an F-18. When we're operating with them—and imagine we're doing basic fighter manoeuvres—there's a good understanding among the pilots of the capabilities of those aircraft. We evolve how we're going to train to account for that. That's at the real basic level.
When it comes to the types of missions we do in NATO, whether those would be aircraft intercepts or air-to-ground missions, every country has a certain level of capability. Some can't drop the most modern ordinance, for example, while others can and that's all captured. When you're working together in an alliance you cater to the strengths of some to the benefit of all.
