By August 2016, the Conquest Brigade had become part of the Turkish-backed Free Syrian Army (TFSA), and aided the Turkish Armed Forces during Operation Euphrates Shield against ISIL. The militia joined the Levant Front in March 2017, while also becoming part of the Division 33, a Levant Front-affiliated unit within the TFSA's 3rd Legion. The unit then took part in the Turkish-led conquest of the DFNS' Afrin Canton from the SDF in early 2018. At the time, it was commanded by "Abu Ahmad Aleppo". After occupying Afrin city, members of the militia took part in large-scale looting of civilian properties. Thereafter, the Conquest Brigade conducted counter-insurgency operations in the Afrin area, and was reportedly targeted by YPG/YPJ guerrilla attacks.
