Emmisary - opening crawl

I am trying to think - is Emmisary unique in that it is the only Star Trek episode to make use of an opening crawl? If not, what other episodes make use of this technique?

Yep, both were used to bring the viewer upto date with relevant information for either the charcters and/or story.
