Random thoughts after re-watching Saga of Tanya the Evil episode 4

This note includes a spoiler.

I watched the Saga of Tanya the Evil episode 4. I watched this series a long time ago, and I liked it, but I forgot most of the story, so before the season 2, I decided to watch again.

This might be the most peaceful episode for Tanya. Tanya studied in a university for a half year. She answered a use case in the university perfectly in a class. Well, she was just an employee in a company in her past life, how could she know these things? Or was that easy enough to learn in a half year? In a day, she took care of a rifle in the afternoon while others were out in the classroom, and from other people, she was someone who really wanted to go back to the front lines and wanted to fight, which was exactly the opposite of what she wanted.

Anyhow, she just enjoyed staying there for a half year and learned, and then she happened to meet a man from a top brass. He invited her in his room and had a chat. Then he casually asked her for what a country should do in the war. At that time, it was 1924, so the war seemed to have been going on for 10 years or more. Then she brought up a chance to become a global war, perhaps from her past life knowledge, and she proposed to avoid losses as much as possible. She thought that was amazing insight and proposal, but that top brass thought she didn't want to win. Then she thought she failed to propose what she said. Anyway, because she didn't want to give the impression of unwillingness to the war, she counter argued that it'd be helpful to build a battalion to attack them. Was that battalion the idea from the WW2? Don't know. Then she thought she made a speech really good, but later, she noticed she completely messed up. That man proposed to the militaries to build a rapid-response battalion and asked her to lead. She couldn't reject it well because she was the person who never say she wouldn't, but that's a problem that everyone thought she was aggressive and loved the front line. She had a communication issue as she never told what she really wanted. What's funny was almost everyone thought she was just a kid and treated her like a kid, except Lieutenant Colonel, Rerugen, if I'm not mistaken, so if she wasn't in a war line, her mistake was somewhat acceptable. Also, Rerugen observed a person pretty well and looked through each person, apparently.

Anyhow, Tanya needed to lead a batallion, but she didn't want to, so she wanted to delay going to the war line in an upcoming global war, and was trying to delay hiring, but applications were too many. So she decided to do something, but then Visha came. It seems Visha still respected Tanya in some ways. Well, look it from her way, Tanya was so young and defeated a company in the Rhine theater and also arranged for her to come to the capital, so she was a respectable person for sure.

Watched 2nd time.

So this story was that Tanya proposed and caused to start the world war and probably fight across many countries. I don't know until which point Tanya will go in this series. What she suggested was what Zettour originally wanted so that was probably the reason why he accepted her proposal too.

She also was fighting to Being X, but how could she win against it? What was an end game? Being X can take over anybody's bodies as far as I've seen, so that means unless Tanya would exterminate everyone else, she couldn't win. Or did it actually exist in a real form and she could fight?
