Friday afternoon, the US Deputy Assistant Secretary of State covering Iraq, Brett McGurk, tweeted out a quick summary of the day's military action agains the Islamic State (ISIS). It's an interesting list:

4/5 At approximately 11:20 a.m. EDT, 4 F/A-18 aircraft successfully struck a stationary ISIL convoy of seven vehicles and a mortar position.

5/5 On two runs, each aircraft dropped one laser guided bomb for a total of eight bombs dropped on target neutralizing the mortar & convoy.

The focus on mortars suggests a goal of the US air campaign is to eliminate ISIS' heavy weapons advantage over the Kurdish peshmerga. And, according to one US official who worked on Iraq, ISIS' convoys are one of its key vulnerabilities.
