As Dave thinks he may be late I suggest we do it this way.
I have a scenario for 2-4 players involving rebel forces waylaying an ESU military supply convey, which I propose to run (I shall just step out and ref it).
As written this does include the NAC but only as background (they pretty much incited the rebellion in the first place). So if Dave makes it he can throw in an NAC battle squadron to support the rebels.
Unfortunately for Dave, ESU fleet command has detected his ships and dispatched a battle squadron of its own to drive them off.
How's that sound?
Dave: You need to put together a 1000 pt squadron - no restictions.
I shall field a 1000 pt battle squadron to match you
I don't have to run faster than the lion I only have to run faster than you
