One strange or dumb thing in the episode is how they have the one Vulcan there (like they always do) and he pretty much goes along with all of it.
I would think a Vulcan would be the first one to say that the plan was illogical.
Sure, maybe your typical Vulcan. But this was a RED SQUAD Vulcan. As a member of Red Squad, he would have an inflated sense of success, potentially succeeding at everything he has ever attempted, and his youthful logic would tell him their chances of success were high.
