I got mine on Drone, don't remember which side is A and which us C in dom, but u spawned on the side with helipad whichever that is. I jumped on the first flag for the free points and then ran to the right down the path between the helipad and the main building. Just BEFORE the area where the building extender across over the path I looked basically straight up and threw. It went across the map bounced off the ground and nailed a guy coming around the corner into the middle area from the opposite flag.
I actually got Attacker as well because he was close enough to the flag to.count as him being on it. --- Time magazine's Man of the Year in 2006! Really. Google it if you don't believe me.
