In First, US Deployed AC-130 Gunship To Attack Pro-Iran Militants In Iraq

"The US deployed an AC-130 gunship over Iraqi territory in response to fresh attacks by Iranian-backed militia fighters who attacked an air base west of Baghdad housing US troops......Already the Pentagon had said at least 60 personnel had suffered minor injuries or in some cases 'traumatic brain injury' in dozens of attacks going back to mid-October.

Pentagon spokesperson Sabrina Singh confirmed in a Tuesday press briefing, "The United States responded using an AC-130 aircraft already in the air and it hit an Iranian-backed militia vehicle and a number of personnel involved in the attack."
She described that the AC-130 was able to track the point of origin for the attack in real-time, resulting in firing back on the militants' positions." ZeroHedge
