Inside the Green Zone, Baghdad activated its missile-defense system to destroy incoming rockets and artillery rounds last night as political parties vied for government buildings in the Iraqi capital, according to the U.S. embassy in Baghdad.

The C-RAM missile defense system can fire up to 4,500 rounds per minute to tear apart incoming rockets and shells.
