Yeah, this have to be said. The Outside World expeditions of the original Survey Corps were decipted (in the Volume 1) as a big disappointment, both for them and for the citizens of Shiganshina. I don't personally think that they reached any big success (before Eren came in and they gained a strategic advantage) besides the Ilsa Langnar encounter with the Talking Titan. As for the knowledge of the Outside World and its terrain, original Survey Corps members (Levi, Hanji) doesn't seem to have any useful informations, since their expeditions were very short.
