p239
You know, I always read 'crews' as technical crew, not as the 'warriors' -- which perusing my TW the other night says basically the ones running the unit (mech/asf/vehicle). I'll chalk this one up as a "Now I know more".
I think I'm also learning more from this thread!
At a minimum, the answer to the OP's question is "no" those 40 represent the crew/staff of the units in those bays.
For the Lung Wang, it's implicitly assumed that it's 6 MechWarriors/Pilots, 28 infantry, and 6 Techs (though TM, p. 239 suggests it should be 30 infantry, for a total of 42).
I had always thought bay personnel were the ship's personnel myself, since SO/CO assumes the ship's crew takes care of all maintenance, repairs, medical issues, etc., but I guess in BT, 11 people can manage this for a 2,600 ton ship just fine. ???
As for where to shove the AsTechs, I usually assume I can fit one per 7 tons of cargo space (the TM rule for the size of a standard quarters)... or just ignore the issue entirely. :-[
