[quote=@DracoLunaris]are we to assume the stuff we brought with us is here[/quote]


No, if you've read the posts then you'll know that all personal items - weapons included - are in the respective Marines' chambers; those that didn't go to their chambers don't have the weapons they bought with them.

A launcher would be fine and useful, the truth being that there may well be elements of both environments you just mentioned.
