have the same weakness as any other army in history. This strategy has
stopped the Romans, Mongols, Swedes and many other prominent armies in
history. It would’ve stopped Alexander the great if the Persians weren’t

The scorched earth policy takes advantage of the fact that soldiers are men who need
to eat and drink. The horses carrying their rations need to eat as
well. The scorched earth policy takes away anything that is edible from
the invading army.
