Used Car Salesman

I got this in campaign (first level near dam) using spikers. I blew up the front turret and it gave me this achievement. I was never able to reproduce the event though... 24.18.240.159 03:16, 21 January 2008 (UTC)

I got this accheivement via the glitch way. On the Covenant, I destroyed a phantom with a Hornet, but blowing up the turret. I knew I'd done it, bacause i have the scout helmet :) But I may be confused...
