Yeah, but after nine seasons, they've rooted themselves in either defending themselves from dangerous humans or the paranormal. The Jennings are more along the line of those going after Mulder and Scully. While their talents may help them in fighting, the more disciplined trained of the KBG gives them a greater edge since I see them more as the attackers, unlike Mulder and Scully who will take more of the defender.

I haven't finished the X-Files yet, so I don't understand the whole 'Suclly is Immortal' point. Don't ruin it for me.
