Re: why didnt the voyager crew have tng uniforms
I once read a British Army Officer during the 2nd World War had to order a retreat from a town they had been holding for days and shaved just before doing so, as if your going to have to retreat your going to do it with dignity.
Could just be practical as that officer taking his last chance for a hot shower and shave for awhile if he's retreating out to the wilderness.
