Will these extra troops help wipe out ISIS and should they have been there from the beginning?
The US is to send 200 extra troops to Iraq to help fight so-called Islamic State (IS), officials say.
The deployment will increase the number of US personnel in Iraq to about 4,100.
Alongside the additional troops, Apache attack helicopters will be deployed for the first time against IS in Iraq.
US Defence Secretary Ash Carter made the announcement during an unannounced visit to Baghdad, where he met with US military officials and Iraqi Prime Minister Haider al-Abadi.
The US also plans to give Kurdish Peshmerga forces, which are fighting IS on the ground, more than $400m (£280m; €350m) in assistance.
Most of the additional 200 troops will be special forces, according to the Associated Press. The remainder will include trainers, security forces for the advisers, and maintenance crews for the Apaches.
