There are three episodes to this: 1 episode for the movie special, and 2 episodes for Yukari explaining the new tanks involved in the film. I recommend watching the special. It's a nice epilogue to what happened in the movie. Our main cast and other Oorai girls get to know Shimada Arisu. It's an easy 7/10. However, as I said in my review of Yukari's tank special [link: https://myanimelist.net/reviews.php?id=532749 ], not everyone will like these episodes, including me. These are well-made and well-researched episodes, and if you're a tank geek, you will love them. However, because I do not like it, I give these a 3/10. So theoverall score of this is 5/10. I have mixed feelings about Yukari's episodes, but I recommend the movie Special.
