What is the "Power Player" Medal?

Sorry for the simplicity of this thread, but since I couldn’t find any success on Google or using the search function I figure I would ask.

I have gotten the “Power Player” medal a couple of times and I’m wondering if anyone knows what it is.

There are a bunch of medals I’m wondering about but have no clue about.
343i doesn’t have a medal list or even a damn carnage report.

I just got this myself I think that it has to do with getting to 20 kills on your team first… Kinda of like getting to ten kills first gets you the Top Gun medal… that’s my guess.

10 kills with a power weapon

And we have a winner!
