Summoning Russia (event focus)

As the title suggests, the story will focus solely on battles.
I only take the source from the fandom which includes almost everything is narrative.
I didn't make it like a novel because someone had already made it.
Sorry this is my first time making a story like this, sorry if there are a lot of mistakes in my language
And some may look very similar to fandom in some parts, because I'm more interested in the tactical part only (when russia is involved/creating a new plot)
