Last I checked (which was a few months back, mind you), the Patriot, SA-10, and most ships could do anti-missile defense. I thought the Roland could, too, and the Hawk, SA-8, and SA-11 can shoot the Kh-31P, if nothing else. Also, the SA-19 uses its guns on the Kh-58U. What uses the HQ-7? I didn't know about it.
