I haven't personally watched old war strategies at play (just not really much of my thing) and this is the first time I've seen a take on it. I don't know if that's how people back in the day calculate things during wars, but that was honestly impressive and adds a lot to the immersion. Once again, the powers behind all these actions committed in the real world can't help but surprise me. I love how there's a lot of thought given into their own plans and motivations.
