The 2015 Northwestern Syria offensive, dubbed by the rebels as Battle of Victory,[27][28][29] took place in Idlib and Hama.

The campaign consisted of a three-pronged attack, with the two main assaults spearheaded by Ahrar ash-Sham, al-Qaeda's al-Nusra Front, and other Sunni Islamist factions under the banner of the Army of Conquest, and the remaining attack force including collaboration with Free Syrian Army groups.

[30] The commander of the 13th Division, affiliated with the FSA, stated that coordinating with other groups such as al-Nusra Front did not mean they were aligned with them.

At least 12 government fighters and 9 rebels were killed, while a number of armoured vehicles and tanks were destroyed by BGM-71 TOW missiles.

[48] The military leader of "Qawat Al-Fahoud" (Cheetah Forces), Colonel ‘Ali Al-Hajji was killed, while the leader of “Qawat Al-Nimr” (Tiger Forces), Colonel Suheil Al-Hassan was wounded in a rebel mortar attack on a government military camp.
