Dr.Roller:
I think there is a good chance that it may not be too late to request something (LS will surely tell me no if it is).
(I won't be acquiring any disposable rockets when I already own an M3E1 that has laser targeting and is capable of firing everything from straight HE to Guided Multi-warhead rounds up to 1200m. This is partly because the GM of this game is not interested in excessive crunchy stuff so one "Rocket Launcher" is probably enough.)
For sure, if anyone can think of anything they might have requested from Doc Roller, I'm happy to retconn it in. Part of the fun of a one-shot is for you to get everything you want so I can throw everything I want at it.
And Doc is right, it's not my thing, but if you want to geek out over the specific benefits of specific model of weapon, go for it. Even if you bring your real-life knowledge to bear and tell me "By the way, this one rocket launcher I'm using also plays trance music" or whatever, I'm happy to take that into account. I have my real-life topics that I'm super nerdy about (ask me about tarantulas some time), so I totally get it.
But that kind of things is outside my knowledge base and my 'Okay Winging It' Zone. So a little slack cut on both sides might be necessary.
