There's no eye to this storm

Astride vortices
Invisible Banshees strike
Like a thunderstorm

The banshee is a powerful unit, well suited to its primary task: covert strikes. It rises on twin twisters, driven by dual turbines. It cloaks itself, becoming as incorporeal as the wind itself. It approaches the enemy silently, unseen. And then it blows the snot out of that mineral line!
