The video posted above showcases the spoils of war gained in the taking of Liwa' 93.
On August 9th, the Islamic State fully took over Liwa' (Brigade) 93 in ar-Raqqa governorate. In late July, IS took over the Syrian Army's Division 17 headquarters in the same governorate. Now that the IS is in control of both of the aforementioned military installations, all they have left to take is Tabaqa military airport. If their recent advances in both Syria and Iraq is any indication, the Tabaqa airport is most definitely their next target.
By taking the airport, they will have complete control over ar-Raqqa governorate. This would be the first full administrative division of Syria that the Assad regime has lost. This would also act as a move of further consolidation of their power in Syria. The goal of taking over ar-Raqqa should come as no surprise as their capitol is in Raqqa city.
What could potentially be their next course of action is focusing on Dayr az-Zour and ridding the province of regime forces, rival rebels, and evenrebellious former allies of Sunni tribes in the region. Taking complete control over Dayr az-Zour would allow the IS much easier access to and from Iraq (much easier than it is now, which already appears to be easy). This would allow them easier control over the flow of troops and equipment either needed for fights in Iraq or Syria. Not to mention, it would act as a massive propaganda victory--akin to how it will be when and if the IS takes over Tabaqa airport in ar-Raqqa.
I will keep this updated if the IS makes anymore significant gains in both Raqqa or Dayr az-Zour.
Below are some pictures of their gains in the taking over of Liwa' 93:
