That's how I see them. IK reads the files and briefing papers. He studies the maps and knows the routes in and out, and the secondary routes in case the primary routes are closed. He knows whats believed about their opponents. And then he can give NS as much as he actually needs of it.

NS studies the site as they enter, he reads the moods and intentions of their opponents. And he can manipulate them and bamboozle them using what IK has told him in advance.

They both know their stengths and play to them.
