Pentagon press secretary Rear Adm. John Kirby said Friday that two F/A-18 jets dropped 500-pound bombs on a piece of artillery and the truck towing it. The Pentagon said the military conducted the strike at 6:45 a.m. ET, against terrorists with the Islamic State (IS), the group formerly known as ISIS.
“As the president made clear, the United States military will continue to take direct action against [IS] when they threaten our personnel and facilities,” Kirby said.

Sounds limited, but if we do not get involved, there will be mass genocide, no question.
