As I can see,the mission is full of grammar errors....
Which means that someone who doesn't speak English made it,right?
Oh,there's the GTCv Steadfast....uhm...

Excellent, that's a lot better than I could do. "Rest quarters" makes some sense for U5. I'm not sure about U1 though; "were summoned to" makes sense but I can't hear any "to" in there at all. That and U2 are for the most part all that's left. I'll update the original post.

In the first briefing, it sounds like "we have come to".
In U2, I got "no further messages have been sent, doubtless to avoid attracting the Shivan's attention."
In the second debriefing, it's "neglected", not "neglect".
