How Strong Is Iran's Military?

The Iranian Constitution of 1979 declares that the country's defence forces are an "ideological army" responsible not only for national security but to be proponents of "God's law" throughout the world.As such, the Revolutionary Guard is the single most important and influential institution in Iran, with profound influence over civilian life and a key role in spreading Iran's influence overseas.However, the US has a vastly greater overall population and the world's most advanced military apparatus, with a history of using nuclear weapons.It also remains allied with the most powerful and prosperous nations not only regionally, but around the world.
