Many here seem to think Iran doesn't have much to bring to a battle.
Here is a report from NPR stating the opposite.

This from that report:
"Is this part of a large arsenal? I mean, how many other types of weapons does Iran have at its disposal?
BRUMFIEL: Iran has quite a few other types of weapons. It has suicide drones, it has cruise missiles - those were both used in an attack against a Saudi oil facility last year - it has anti-ship missiles, it has air defense missiles that it used to shoot down the U.S. drone. I believe that was last year as well. I mean, this is important to understand. This is not, you know, a militia. This is a military. And they have a number of relatively sophisticated systems like this that they can use in different ways.
GREENE: Can the U.S. do anything to stop attacks like these that we saw here?
BRUMFIEL: It's pretty hard to do. I mean, these are ballistic missiles. As I said, they come in really fast, and they also are difficult to intercept. Now you can try to strike them before they launch, but Iran tends to disguise its missile trucks as civilian vehicles. They've reportedly dispersed those trucks already from their bases, so you'd have to go into Iran to try and find them. And if you did that, you'd be up against their air defenses. So the U.S. may not have a lot of good options for stopping these kinds of attacks.
GREENE: A lot of information there from NPR's Geoff Brumfiel. Geoff, thanks so much.
