>>507177673 (OP)Iran is neither Iraq 2.0 nor Afghanistan 2.0, and the US military knows it. Iranian combat tactics are specifically designed for the sole purpose of resisting an American invasion. The entire country is separated into sectors, each with its own troops, military infrastructure and hidden caches. The idea is that each sector can operate autonomously, self-sufficiently and decentralized for long periods of time even if central command is completely destroyed. In this way, each sector is expected to inflict the greatest wear and tear possible. Obviously the Iranians are not betting on a conventional victory, but rather on wearing down the American troops enough to force them to withdraw. Iran has much more population than Iraq or Afghanistan, a huge territory and a much more educated population, which means that a guerrilla not only has ample spaces to hide, but also has human resources trained enough to manufacture their own homemade weapons, from drones to explosives.
