Baron Blade and turrets.

My and some friends were playing the Baron Blade scenario of Sentinel Tactics, where you Baron Blade gets to lay down turrets and then in the next misssion, the heroes have to destroy pylons that will be protected by said turrets.  But as we were playing through, we realized we had no idea as to what turrets exactly Baron Blade has access to or how the work, nor could we find mention of it.  I've searched and searched and I still can't figure it out.

Any of the sideways target cards that have the word Device on them are Baron Blades turrets.

Turret Installation says put a device marker in play.

They are also mentioned in the Continuing the Story section of the scenario rules by name.

Ugh, I didn't even think to look through those cards.  I feel like an idiot.
