On 25 August 2016, the commander of the Northern Division, Lieutenant ColonelFares Bayoush announced that talks are made in Idlib on the unification of the three FSA-affiliated rebel groups in northwestern Syria. He stated that eventually the merger will be complete and the three component groups will dissolve into the main faction. At it establishment on 19 September 2016, the coalition aims to prioritise fighting the Syrian government and establish relations and coordinate with the Salafist factions of the Army of Conquest, including Ahrar al-Sham and Jabhat Fateh al-Sham, al-Qaeda's renamed al-Nusra Front. However an opposition source stated that the Free Idlib Army will not closely cooperate with Jabhat Fateh al-Sham. Just a day before, the Mountain Hawks Brigade withdrew from the front against ISIL near Jarabulus and Azaz in order to head to southern Aleppo and Idlib. The commander aims for an eventual full merger between the 3 groups after forming a new command structure. On 23 September Russian warplanes bombed a cave in Taybat al-Imam, killing 22 fighters from the Free Idlib Army. In early October a number of Mountain Hawks Brigade fighters defected to join Jabhat Fateh al-Sham due to several disagreements, mainly due to the established of the Free Idlib Army. In November, the deputy commanding general of the Free Idlib Army, first lieutenant Mohammed Khaled Bayoush, came under fire from machine guns fired by unknown assailants while in his car near the town of Kafr Nabl. The commander escaped without injury. On 25 December 2016, 2 FIA commanders were shot and killed in Maarat. Opposition activists accused Jund al-Aqsa of conducting the assassination. The next day, the al-Nusra Front raided houses throughout Idlib and captured 16 FIA fighters from the Mountain Hawks Brigade. The rebels were captured on charges of participating in the Turkish military intervention in Syria. On 23 January 2017, the 13th Division of the FIA repelled an al-Nusra advance toward Maarat al-Nu'man. On 25 January 2017, the groups of fighters which left the Mountain Hawks Brigade in September 2016 for Jabhat Fateh al-Sham, returned, along with their leader, Lt. Col. Nasha'at Haj Ahmad. On 31 January 2017, Lt. Col. Fares Bayoush resigned from his positions in the Northern Division and the Free Idlib Army, citing "Black Standards" in Idlib. On 5 April 2017, a vehicle carrying Lt. Col. Ahmed al-Saud of the 13th Division and Colonel Ali al-Samahi, chief of staff of the Free Idlib Army, came under fire from Hayat Tahrir al-Sham fighters at a checkpoint near Khan al-Subul, which was under complete control of HTS. Al-Samahi and another fighter was killed in the shootout while al-Saud was wounded and was transferred to Turkey for treatment. As a result of internal disputes between the 13th Division and the other factions in the Free Idlib Army, some members of the former reportedly released a statement on 11 April which claimed that the 13th Division will no longer be part of the Free Idlib Army and it will instead join the "central operations room" led by Col. Fadlallah al-Haji of the Sham Legion. This was denied by Lt. Col. Ahmed al-Saud, the overall commander of the 13th Division, who called the statement a "false report". Al-Saud called on all the member groups of the FIA to integrate under one organization. On 11 July 2017, the Free Idlib Army appointed new commanders: Lt. Col. Suhaib Leoush, Capt. Naji Mustafa, and Capt. Dumar Qanatri. In May 2018, along with 10 other rebel groups in northwestern Syria, the Free Idlib Army formed the National Front for Liberation, which was officially announced on 28 May. Lt. Col. Suhaib Leoush was appointed as the formation's deputy commander. On 7 March 2019, Amin Haj Ali, a field commander of the free Idlib Army, was killed by an IED in southern Idlib. The unit subsequently fought alongside other rebel factions against the government's northwestern Syria offensive from April 2019. On 31 July 2019, Col. Afif Suleiman, commander of the Free Idlib Army and member of the National Front for Liberation's command council, was arrested by Hayat Tahrir al-Sham's security force at a checkpoint near Darat Izza as he was driving from Afrin District to the northern Idlib Governorate. Suleiman was detained in HTS's Oqab Prison in Jabal Zawiya, and released two days later.
Equipment
The Free Idlib Army is known for possessing several new BM-21 Gradmultiple rocket launchers which they used to bombard Syrian Army positions in southern Aleppo. In 2016, one of the group's commanders, Fares Bayoush, confirmed that the rocket systems were newly supplied from foreign sponsors.
