Reaver probably attack from either ambush or boarding action I agree. Or considering how much of the tech relies on handwavium they have something that neutralizes handwavium for a bit. Losing pressure, communication (seriously, hardtech comminicators that can reach over light seconds are big and expensive), lifesupport, engines and a bunch of other things in an instant got to suck.
Boarding actions would make for some nice drama, so that gets my vote for what the raiders are doing.
EDIT: Oh and to awnser your question, no I don't think we have setteled on a way that the reavers attack.
E: "Did they... did they just endorse the combination of the JSDF and US Army by showing them as two lesbian lolicons moving in together and holding hands and talking about how 'intimate' they were?"
B: "Have you forgotten so soon? They're phasing out Don't Ask, Don't Tell."
