Runaway Shredder!

I've been trying to impress our new Horde allies with our legendary goblin efficiency, but in hindsight automating the shredders was a bad idea. Now they're mindless killing machines, rampaging over the countryside. Don't get me wrong - that kind of thing has its place - but for the time being I need a brave ‹class› to help me get these things under control. It's easy. Automated shredders, like all machines, must first be beaten into submission. Afterwards, seize the controls and I'll radio you instructions.
