I earned my first one last night. I didn't even know that existed. The spark carrier dunk animation had already started when I shot him with my Ice Breaker. I got lucky but as PVP scrub, I'll take it. Who else has earned this medal? Fun Trivia: Coincidentally, the spark carrier happens to be one of my LFG Raid Friends whose fireteam matchmade into a match with my team of randoms (I was playing solo- no fireteam).
