Greetings, everyone. Such an interesting means of communication. I can think of several ways that this would be useful back home. I am Erwin Smith, though...I suppose I should leave off "Commander" now that I am here. I am not surprised that Hange has already leapt in and said hello.
Normally, I would be trying to recruit you all to join the Survey Corps, but, alas, we are not back home. So this is what it's like beyond the walls. Interesting.
