Called ADAM, the small white trailer with the big laser takes its cue from radar blanketing the area three miles out. The radar has already kicked the laser awake when the guys on watch saw the flash. By the time they're diving for cover and warning their buddies, the ADAM has locked onto the rocket and is burning it out of the sky from over a mile away. Yeah, with a max range of 2 klicks, you're going to need a lot of small white trailers for coverage - PROFIT!
Iron Dome, already 70km. interception range.
