General Caine: I want to highlight that the incredible work that the Ukraine industrial base is doing as they scale their own capabilities. It ranges from their surface-to-air capabilities to their air-to-air capabilities. I'll note that recently we had the first air-to-air kill where a Ukrainian F-16 shot down a Russian fighter. So I think their ability to scale their layered defense has come along a long way over the past couple years with the help and assistance of many.
