The Battle to retake Ramadi, capital of Iraq's Anbar province, will pit the Islamic State jihadists against a myriad of fighting forces. A short description of the main players follows: - ISLAMIC STATE IS scored its biggest victory since the summer of 2014 when it took control of Ramadi on Sunday. The jihadist group and its previous incarnations have maintained a presence in the Ramadi region for the past decade, even after US-led efforts to remove insurgents from Anbar.
