The most common western comparison I can think of would be the Nuland/Kagen Institute for the Study of War.
The Ukrainian forces are retreating into defensive positions today. It is obvious a major Russian offensive is coming in short order. The Russians just laid out how to build and layer defenses to defeat this Russian offensive. The idiots in the Pentagon won’t even consider trying to ape the overwhelming successful Russian stand. That is why the Russian offensive will also be an overwhelming success.
