This is a very symbolic day for the Syrian war. The garrison repelled dozens of attacks and assaults, even being in split into two parts, besieged, deprived of a full supply, and yet confounded all the skeptics waiting for reinforcements.
Of course, this is only the formal access to the base. Need to tighten up supply, you need to connect with a garrison cut off of from the air base. You need to clear the areas North and South of the area extending to the city and need to prepare for hard battles for the liberation of that part of the city, which still holds the militants.
