The Islamic State of Iraq and the Levant has blitzed across Iraq over the past couple of weeks. The Sunni extremist group threatens the government of Iraqi Prime Minister Nouri al-Maliki, a Shi'ite and a close ally of Iran.

The Islamic Repulic isn't taking its chances, and has already sent two units of the Revolutionary Guards into Iraq. These soldiers come from one of the largest and most capable militaries in the region.

Iran's military has 545,000 active personnel and some of the most advanced technology of anyone in their neighborhood. The United States gave them a lot of it.

Granted, it wasn't the Islamic Republic of Iran that we supplied with some of the hottest tech available at the time. Rather, it was a pre-revolutionary monarchy that was a key ally of the United States in the Middle East - and was overthrown in Iran's Islamic Revolution in 1979.

Since then, Iran has managed to develop its own military-industrial complex and upgrade its existing arsenal.

And they've gotten pretty good at it.

With Iran's military jumping into the unfurling chaos in Iraq, we looked at some of the military toys that the Iranians are playing with.
