December 19, 2016 - Emily Anagnostos

Operations in eastern Mosul largely paused from December 13 to 19 likely in order to stem the growing casualties taken by the Iraqi Security Forces (ISF) and to regroup before pushing into central Mosul. Meanwhile, the Popular Mobilization continued its push west, connecting its parallel lines of effort when it recaptured the north-south road between the Tel Afar Airbase and the southern town of Ashwa on December 13.

ISW on Aleppo and the Broader War in Syria

December 14, 2016 - Institute for the Study of War

The pro-Assad forces’ onslaught in Aleppo marks a key inflection point for the war in Syria. Eastern Aleppo’s imminent fall – to a coalition that includes Russia and Iran and its various proxies – will accelerate the war’s destabilizing effects. Jihadists will further improve their position within the Syrian opposition. Fighters aligned with Syrian President Bashar al-Assad will continue committing atrocities against civilians. The Russian and Iranian regimes will grow more emboldened.

The Campaign for Mosul: December 6-12, 2016

December 12, 2016 - Emily Anagnostos

The Iraqi Security Forces (ISF) made significant gains in northeastern Mosul from December 6 to 12, but struggled to advance in the southeast. The ISF ordered a change in tactic on December 4 in order to address the lopsided eastern offensive, attempting to make rapid advances in the southeast rather than grind through neighborhood-by-neighborhood clearing operations. The shift, however, failed drastically when the rapid gains left the ISF open to ISIS counterattacks, resulting in heavy casualties on December 6 and 7. In response, the ISF moved units previously allocated to breach Mosul’s southwestern neighborhoods to reinforce efforts in the southeast on December 10.

The Order of Battle of the Ukrainian Armed Forces

December 9, 2016 - Franklin Holcomb

The United States and its partners can improve regional security and stability in Eastern Europe by supporting the modernization and reform of the Armed Forces of Ukraine more aggressively. Ukraine has suffered from consistent Russian military aggression since Russia occupied the Crimean Peninsula and militarily intervened in the eastern Ukrainian Donetsk and Luhansk Oblasts in 2014. The overall unpreparedness of the Ukrainian military and its inability to match the capabilities of Russian forces allowed Russian and Russian proxy forces to gain a foothold in eastern Ukraine from which they continue to destabilize the entire country. The Ukrainian armed forces have been partially restructured and strengthened in the face of this constant pressure, enough to stabilize the front lines for a time. They require significantly more support of all varieties, however, if they are to stop the advance of Russia and its proxies permanently, to say nothing of reversing the armed occupation of Ukrainian territory.

Pro-regime forces backed by heavy airstrikes seized at least fifteen districts in Eastern Aleppo City including large parts of the Old City of Aleppo, shrinking the pocket held by opposition forces by more than seventy-five percent. Meanwhile, Russia and the U.S. met in Germany to discuss a potential deal to evacuate all civilians and opposition fighters from Eastern Aleppo City except for members of Jabhat Fatah al-Sham - the successor of Syrian Al-Qaeda affiliate Jabhat al-Nusra.
