In the Syrian Civil War, which has been raging on for almost four years, most battles take place in cities and small towns in the form of urban combat warfare. Ferocious house to house fighting between the Syrian Army and terrorist Islamist rebels of all kind, some of them armed and trained by the CIA, others, like ISIS, are financed by Islamist groups from Saudi Arabia and other Muslim countries. The Kurdish guerrilla are the only insurgent group who fight against the terrorist Islamist groups, like ISIS. They use all type of infantry weapons, from AK-47 assault rifles to hand grenades and anti-tank rocket launchers.
