The Free Syrian Army (FSA; Arabic: الجيش السوري الحر, romanized: al-jaysh as-Sūrī al-ḥur) is a big-tent coalition of decentralized Syrian opposition rebel groups in the Syrian civil war founded on 29 July 2011 by Colonel Riad al-Asaad and six officers who defected from the Syrian Armed Forces. The officers announced that the immediate priority of the Free Syrian Army was to safeguard the lives of protestors and civilians from the deadly crackdown by Bashar al-Assad's security apparatus; with the ultimate goal of accomplishing the objectives of the Syrian revolution, namely, the end to the decades-long reign of the ruling al-Assad family. In late 2011, the FSA was the main Syrian military defectors group. Initially a formal military organization at its founding, its original command structure dissipated by 2016, and the FSA identity was later used by several different Syrian opposition groups.
The Free Syrian Army aimed to be "the military wing of the Syrian people's opposition to the regime", through armed operations and the encouragement of army defections. In 2012, military commanders and civilian leadership of the FSA issued a joint communique pledging to transition Syria towards a pluralistic, democratic republic, after forcing Assad out of power. As the Syrian Army is highly organized and well-armed, the Free Syrian Army adopted a military strategy of guerrilla tactics in the countryside and cities, with a tactical focus on armed action in the capital of Damascus. The campaign was not meant to hold territory, but rather to spread government forces and their logistical chains thin in battles for urban centers, cause attrition in the security forces, degrade morale, and destabilize the government.
