Sent it to you. Won't post it here because reasons.
EDIT: Btw, spazyak, after giving a closer look to your sheet (I hadn't had time), your sheet needs a lot of cleaning up (it looks really messy, and maybe it's just me, but it is kinda... Underwhelming. I don't know how to explain it), and that backstory is quite lacking and completely ignoring the fact that you aren't exactly an Imperial Guard regiment and that one does not enlist in the Imperial Guard (in some planets, you can, but it is usually not the case). As well as being quite... Well, I don't want to be mean, but there isn't really that much difference between writing that and writing nothing at all.
I know some people find it difficult to write backstory for their characters, but that character, and I mean no offense with this, looks like something thrown out at the last second, after barely giving it any thought (or, in some parts of the sheet, after barely reading the rules). And although I don't like kicking people out of games just because they lack experience, I want this campaign to be something serious, enjoyable for all and engaging. And if I have to play with one or two players fewer than I would like to, I will.
This sounds harsh and drastic. But to be honest, I hardly (if ever) get to play games from the WH40K RPGs. And if I like them is both because of the system and because of the narrative that the setting can provide. So I want to have (And I feel like this is not asking for that much) a good narrative and gaming experience. That character is the kind of character that doesn't belong in the kind of game I'm looking forward to GMing (and the kind of game I presume the others want to play, based on the questions and comments I've read), but rather on a far more short-term, simpler game.
So please, I'd ask you to rethink your character, give it a bit more effort, both in your backstory and your sheet, and post it before this Sunday. If you think you won't be able to do it, I invite you to please step aside and let someone else play.
As I said, I mean no offense with this. I'm just trying to ensure the best experience for all. Usually I'm more patient with these things, but I have had a very bad week. And a very bad summer too, to be honest. And I am running low on patience.
