further up this thread alot of posts were about the 'plot hole' of how on earth the romulans would have been able to capture and hold vulcan. I may be wrong on this one, but i was under the impression that because vulcans are pacifists they dont really have much a strong defence system in place and that they rely on the protection of the federation...
There is speculation that some Federation starships are manned almost entirely by a Vulcan crew (as evidenced by the USS Intrepid in TOS).
Also, the Vulcans had many a space battle, esp with the Andorians, during ENT.
Captain Silva LaForge's USS Hera
from 'Interface' was said to have had a crew of mostly
Vulcans. The USS T'Kumbra
from 'Take Me Out to the Holosuite' specifically had an all-Vulcan crew. Both were over a century after the Intrepid
, so it seems clear that the increased presence of alien crewmen aboard our Hero facilities does not necessarily indicate full species integration.
Alternatively, it could mean that Vulcans are a special case of having their 'own' ships - and perhaps so are certain other races?
