Wouldn't call these scum "troops". More likely al Kuds "specialists". Iran knows if their troops show up in Iraq, they are going to get pounded back to the 15th century.

Most of their government acts like its the 15th century still. You would have to pound them back alot further than that, I'm afraid.

Sixth century sounds about right. Heck, any time until 620 AD (seventh) would be okay.
