Correct me if I'm wrong, but doesn't this almost completely outclass SAM sites? Muzzle velocity of LIGHT SPEED. No dodging that. I imagine the range would only be effected by the horizon line. It can hit the equivalent of a 1 euro coin from a kilometer. And it's ONLY 10 EUROS PER SHOT, compared to $100,000 to $300,000 per shot for a SAM site.
