I expect some MAJOR issues with figuring out firing solutions... the people aiming wouldn't be used to the realities of FTL combat; and I expect that since the Chaos ships are very, very, heavy, they are likely to have pretty solid ranged weapons to. At least, the RT should assume this is the case (Grand Cruiser! Heavy Cruiser! AHHH!!).

But they should be able to kludge together something, after enough attempts.
