"I could beat that army!" Theoryscape Challenge

[Killometer]

Because no opponent in their right mind would allow it, this will probably stay strictly Theory, but imagine a game where you got to see the army you would be facing before you built your own army. How quickly do you think that you could obliterate your foe? In the interest of seeing what people put together I submit this challenge: build an army of 500 points and 24 hexes that can beat the most recently posted army as easily as possible. Feel free to include any specific strategies that you would use as well. And please quote the army you are focusing on, in case other posts show up between yours and theirs. Also, Aldin reminded me that there are a few well known "rock-paper-scissors" counter-army builds, but ideally they won't be rehashed too many times here (it wouldn't be much fun to read the same 3 armies over and over and over as they infinitely counter one another. )

I'll start this off with a little slow-pitch:

Stingers x3 180
Dividers x2 280
Nagrubs x2 340
Su-Bak-Na 500
23 hexes
