The Russian military activities consisted of air strikes, cruise missile strikes and the use of front line advisors and Russian special forces against militant groups opposed to the Syrian government, including the Syrian opposition, as well as Islamic State of Iraq and the Levant (ISIL), al-Nusra Front (al-Qaeda in the Levant), Tahrir al-Sham, Ahrar al-Sham and the Army of Conquest. After Putin's announcement on 14 March 2016 that the mission he had set for the Russian military in Syria had been "largely accomplished" and ordered the withdrawal of the "main part" of the Russian forces from Syria, Russian forces deployed in Syria continued to actively operate in support of the Syrian government.
