Just over a year after capturing Deir ez-Zor's Ayyash weapon depot in the largest arms haul of the Syrian Civil War, the Islamic State has once again got its hands on massive quantities of ammunition captured from a storage depot in Deir ez-Zor. This arms haul joins the list of other major instances where vast amounts of weaponry and munitions traded owners such as the capture of the aforementioned Ayyash weapon depot, Regiment 121, Brigade 93 and the Mahin arms depot, all but the last of which were at the hands of the Islamic State. Each of these depots provided its capturers with a wide array of weaponry, vehicles and ammunition that could immediately be used against their former owners, a major blow to other factions fighting for control over Syria.

The rise of the Islamic State from an militant group operating in Iraq to a self-proclaimed caliphate controlling large swaths of land in Iraq, Syria and further abroad has had a significant effect on the course of the Syrian Civil War, effectively hijacking the revolution's original goals and drastically changing the scope of warfare in Syria. At the forefront of this change is the Islamic State's ability to quickly adapt to the various situations that can be encountered on the battlefield, allowing it to become one of the most sophisticated designated terrorist groups to date.

Jaish al-Islam has once again secured its place in the spotlight after firing at least two Iranian Zelzal-2 artillery rockets against regime positions in Syria on the 6th of March 2017. Jaish al-Islam had previously deployed one of its Zelzal-2s in retaliation for the continued airstrikes on Jaish al-Islam held Eastern Ghouta on the 31th of August 2015, and although the target and results of the underreported attack remain unknown, the strike confirmed that the threat of a non-state party firing off long-range rockets was very real. A video of the March 2017 launches can be seen here.
