Guild Wars 2

Can anyone tell me what the Tactivators are in WVW. There are quite a few of the switches, but when I click on the “interact” nothing happens. Please enlighten me on what these do and how to activate, it would be greatly appreciated. Thank you.

I wonder about that as well.

A guild that claims the object can choose certain tactics for it which can be activated with those Tactivators.
