Interesting, just yesterday I discussed with a friend of mine how dumb it is for Putin to attack and try to capture Kiev, because urban warfare is very difficult and usually leads to very heavy casualties. She asked "why?" and I realised that I have an intuitive understanding about this because I've played Call of Duty and she hasn't (obviously not saying that CoD is representative of actual war, but you get the idea of what a sniper or machine gun nest in a city is just from game mechanics). Things that are obvious for some people are absolutely not obvious for others.

Btw, Pavlov's House defence is mentioned in the article and there's a corresponding mission in CoD.
