Earlier in my game I made Hardin the elder of the BoS in Hidden Valley.

I've decided to side with NCR in this game, so I need to go take out the BoS. I planned on using the security terminal in Ramos' office to dice them up with their own turrets only to find...there are no turrets. Anywhere in the bunker. They're just simply gone. I tried re-loading the game, but they're still gone.

I'm wondering if this is a bug, or if it's supposed to happen when Hardin becomes the elder?

Sounds like a bug, unless you actually already hacked the turrets.
They probably lasts like 5 secs against the Brothers....
When they are destroyed they are just gone, no remains.

I remember one time when I didn't save, I decided I'd try out what would happen if I hacked the turrets, and I heard fighting for awhile before the turrets were destroyed. This time I heard nothing, and I even ran down the hall before hacking after I loaded to check if the turrets were there. Nothing.

Oh well, I guess it's just a bug. *Rolls up sleeves* Guess we'll just have to do it the hard way! :gun:

When I hacked the Turrets they killed off all the BOS People with ease.

Yeah, my joking around hack of their turrets, about half of the Brotherhood got taken out before they finally blew up the turrets. So much for softening them up, we're doing this manually.

12.7mm SMG or Grenade Machine gun will work best.

More like a Pulse gun or Zap glove.
