Although the 4th Corps' initial operations such as during the 2015–16 Latakia offensive and Northwestern Syria offensive (October–November 2015) were relatively successful, the inclusion of more militias into the corps remained elusive. This was probably due to the fact that Iran remained unwilling to allow Syrian units under its control to be integrated to a primarily Russian-led formation, while many militias generally resisted any attempts to reduce their autonomy by including them in the 4th Corps. As result, the 4th Corps remained mostly limited to Latakia, where it continues to be active. As its performance during the 2016 Latakia offensive was lacking, however, its overall commander Maj. Gen. Shuqi Yusuf was dismissed in July 2016. Overall, the 4th Corps did not "live up to Moscow's expectations" and its Syrian commanders "demonstrated poor performance", despite the fact that the corps had actually succeeded in reforming the included militias into a "disciplined, organized military force".
