Building density, as well as an extensive network of underground tunnels significantly complicate the promotion of government forces. However, thanks to the upgraded technology, as well as competent actions of military leaders, the army team can beat a meter by meter.
Yarmuk is a former Palestinian refugee camp. Uncontrolled buildings turned the area into an impassable labyrinth. From any window, at any time there may appear an action with a grenade launcher or a sniper. Therefore, the Syrian army has to practically compare with the ground every house that stands in their way. Nevertheless, a wide network of underground communications allows terrorists to quickly move to a safe area.
