I'm not sure how popular this unit has been in the past but I used the Dora Rail Gun in my scenario and in the process i made civlopedia and unit 32 file. They are not that great but something is better than nothing.
No there are, just have to DL them seperately. Striq did not make the animations, just the add on files to go with them. So he reasonably did not include the work of others in his post.
The file is probably here, and I know it is on civ3files.com
or you can just get Wyrmshadows unit. His are always complete (except for sound, which he leaves to you).
