Actually the GM is waiting for your status report, so that the Lord can order you to wait for the rest of the guys to turn up, and inform you that he will send cultists as meat shields to send in against the bridge guys first That is unless you want to try and solo the bridge and, though you'd kill a few, undoubtedly die under the heavy return fire EDIT: Actually, now that I think about it, how does your guy know there's cargo on the bridge? It's certainly not the usual routine, and as far as I can tell he hasn't been told of it yet
Codex Astartes states that the most important things are to be guarded by Space Marines. Furthermore it is to assume that the leading officer protects valuable cargo - such as relics - himself. Though my guy just wants the fancy weapon the leader has ; they always have the fanciest weapons. (Like Uriels Power Sword) And you want to give me status report so the guys might perhaps hear that I am a traitor and not a pathetic Serf I attempt to be? ^^ Codex Astartes states that behind enemy lines that Radio Silence is to be kept. (That I know for sure as it is in 'Courage and Honor' I can give you page and quote reference if you like )
I know your guy sticks to the codex, more or less, but the Lord pisses on the codex and disobeying him may result in being strangled with one's own intestines There's no reason to presume there is any important cargo at all, this isn't a freighter, it's an escort ship The Ultras held at the bridge because it's a hell of a choke point, it's incidental that there happens to be some loot to be had there. I get that he wants to kill them, I'm not denying that Hey, if you'd prefer they open the door and all open fire, then I can write that. But you'll be pinned and without anyone to support. Just saying, hang back, let the other guys get there, and use the cultists so that they can die instead of you lol.
There are Ultramarines - of course there is precious cargo (Also why would we be sent there if not for getting something fancy? The guys from above ALWAYS know where shit is and we get send where shit is XD) EDIT: But there have your darn status report even if it's only a 'I killed stuff' report xD
