The Eighth Brigade was a unit of the 5th Corps established in 2018 in the Daraa Governorate, Syria during the Syrian civil war, composed primarily of rebels who had reconciled with the Assad regime in 2018. The faction joined the Southern Operations Room in December 2024 following the 2024 Syrian opposition offensives and disbanded in April 2025 after the killing of Bilal al-Droubi.

The Eighth Brigade originated as the Syrian rebel group Youth of Sunna Forces, which was initially led by Ahmad al-Awda until Mohammed Tohme and his deputy Bilal al-Droubi were given control of the group by the factions' leadership council in August 2016. Al-Awda regained control of the group and the city of Bosra later that month with the support of the Yarmouk Army.

Following a marked increase in regime activity in the summer of 2018, al-Awda negotiated a settlement with Russia and was given control of his own brigade. The faction worked closely with Russian military police and their joint area of control was more peaceful compared to other areas of the governorate. Russia ended support for the group in 2021 and it affiliated with the Military Intelligence branch in Suwayda.

The Eighth Brigade raided a group on 5 May 2022 that was planning assassinations of Syrian Brigade Party members, under the orders of the Air Force Intelligence Directorate.

The Eighth Brigade and Central Committees were engaged in a 10-day operation against ISIS in the city of Jasim in October 2022.

The brigade was involved in "fierce battles" with ISIS in various Daraa neighborhoods, including Tariq al-Sad and al-Mukhayam, in November 2022, alongside allied "local factions."

The Eighth Brigade and local groups fought against ISIS in Nawa in January 2024, killing eight members of ISIS.

The brigade joined the Southern Operations Room in December 2024, affiliated with the Syrian opposition and was one of the factions that marched on Damascus, leading to its fall that month.
