While cautioning the idea is “pre-decisional,” a British general working with the U.S. in Iraq indicated Thursday that U.S. commanders may seek additional U.S. trainers to help Iraqi forces “sustain their momentum” against the Islamic State.

British Army Maj. Gen. Doug Chalmers, briefing reporters at the Pentagon via teleconference, said high-level discussions are underway about what additional capabilities might be needed to accelerate the progress of Iraqi troops, but insisted it was the sort of routine review that is always underway. “We’re constantly looking to see if we’re right-sized.”
