Russia throughout history has used scorched earth policy as a war winning tactic. Time after time, it has pillaged, burned crops, destroyed anything of value to an invading enemy. Then, when the invading force is out of supplies, starving and suffering from the dreaded russian winter it strikes with overwhealming force.
So scorched earth is a valid tactic but as far as dominions goes, probably only Ermor, Ashen Empire could use such a tactic as effectively as Russia does.
Note I am not suggesting Russians are the walking dead or anything...
