The Rojava–Islamist conflict, a major theater in the Syrian civil war, started after fighting erupted between the Kurdish People's Protection Units (YPG) and Islamist rebel factions in the city of Ras al-Ayn. Kurdish forces launched a campaign in an attempt to take control of the Islamist-controlled areas in the governorate of al-Hasakah and some parts of Raqqa and Aleppo governorates after al-Qaeda in Syria used those areas to attack the YPG. The Kurdish groups and their allies' goal was also to capture Kurdish areas from the Arab Islamist rebels and strengthen the autonomy of the region of Rojava. The Syrian Democratic Forces would go on to take substantial territory from Islamist groups, in particular the Islamic State of Iraq and the Levant, provoking Turkish involvement in the Syrian Civil War.
The Army of Revolutionaries, or Jaysh al-Thuwar, is a multi-ethnic armed Syrian rebel coalition that is allied with the primarily Kurdish People's Protection Units (YPG) and participating in the Syrian Civil War as part of the Syrian Democratic Forces (SDF).
The 2015 al-Hawl offensive was an offensive launched by the Syrian Democratic Forces (SDF) during the Syrian Civil War, in order to capture the strategic town of al-Hawl and the surrounding countryside from the Islamic State of Iraq and the Levant (ISIL).

The main goal of this offensive was to capture the strategic city of Al-Shaddadi and the remainder of the southern al-Hasakah Governorate from the Islamic State of Iraq and the Levant (ISIL). During the offensive, the US-led coalition conducted more than 86 airstrikes in Al-Shaddadi and the nearby areas, in support of the SDF advances.
The Manbij offensive, code-named Operation Martyr and Commander Faysal Abu Layla by the SDF, was a 2016 military offensive operation by the Syrian Democratic Forces (SDF) to capture the city of Manbij from the Islamic State of Iraq and the Levant (ISIL), and eventually, the ISIL-held areas through Al-Bab to Herbel, in the area referred to as the "Manbij Pocket" in the northern Aleppo Governorate. The main goal of the offensive was to cut off ISIL's last supply routes from Turkey, and to prevent ISIL fighters from escaping across the Syria-Turkey border. For the first five days of the offensive, the US-led coalition conducted over 55 airstrikes in support of the SDF. After capturing Manbij city on 12 August, the SDF announced that the offensive would continue until the whole countryside around Manbij was captured, though the offensive effectively ended shortly after the Turkish Armed Forces initiated Operation Euphrates Shield to prevent the SDF uniting the regions of Rojava.

After 30 May, the offensive stalled, as the SDF shifted its focus and resources to another operation in the northern Aleppo Province.
Operation Euphrates Shield was a cross-border military operation conducted by the Turkish Armed Forces in the Syrian Civil War which led to the Turkish occupation of northern Syria. Operations were carried out in the region between the Euphrates river to the east and the rebel-held area around Azaz to the west. The Turkish military and Turkey-aligned Syrian rebel groups, some of which used the Free Syrian Army label, fought against the forces of the Islamic State (IS) as well as against the Syrian Democratic Forces (SDF) from 24 August 2016. On 29 March 2017, the Turkish military officially announced that Operation Euphrates Shield was "successfully completed".

The Battle of al-Bab was a battle for the city of al-Bab in the Aleppo Governorate that included a military offensive launched by Syrian rebel groups and the Turkish Armed Forces north of al-Bab, a separate Syrian Democratic Forces (SDF) offensive east and west of the city, and another Syrian Army offensive from the south of the city. The northern Turkish-led forces intended to capture al-Bab from the Islamic State of Iraq and the Levant (ISIL), as part of the Turkish military intervention in Syria. By the end of the battle, the Turkish-led forces had captured al-Bab, Qabasin, and Bizaah, while the Syrian Army captured Tadef and other areas further south, with the SDF making gains further to the east and the west.
The East Aleppo offensive (2017), also referred to as the Dayr Hafir offensive, was an operation launched by the Syrian Army to prevent Turkish-backed rebel forces from advancing deeper into Syria, and also to ultimately capture the ISIL stronghold of Dayr Hafir. Another aim of the operation was to gain control of the water source for Aleppo city, at the Khafsa Water Treatment Plant, in addition to capturing the Jirah Military Airbase. At the same time, the Turkish-backed rebel groups turned towards the east and started launching attacks against the Syrian Democratic Forces, west of Manbij.
The Battle of Tabqa, part of the Raqqa campaign (2016–17) of the Rojava-Islamist conflict, resulted from a Syrian Democratic Forces (SDF) operation against the Islamic State of Iraq and the Levant (ISIL) to recapture and secure the Tabqa Dam, al-Thawrah (al-Tabqah), Tabqa Airbase, and the surrounding countryside.

Led by Absi Taha, Alexander Khalil, and Alexander Alaa, it also joined the Syrian Democratic Forces (SDF) in November 2015. The initial members of the group originated from Jabal Zawiya in Idlib, and it has recruited Arabs from Idlib, Aleppo, and other cities in northern Syria since allying with the YPG. Since joining the SDF, the unit has begun to operate across much of northern and eastern Syria, participating in operations against anti-SDF Syrian opposition factions, the Islamic State of Iraq and the Levant, the Turkish Armed Forces, and the Syrian National Army.
The Deir ez-Zor campaign, codenamed the al-Jazeera Storm campaign, was a military operation launched by the Syrian Democratic Forces (SDF) against the Islamic State of Iraq and the Levant (ISIL) in Syria's Deir ez-Zor Governorate in 2017 during the Syrian Civil War with the goal of capturing territory in eastern Syria, particularly east and north of the Euphrates river. The U.S.-led Combined Joint Task Force – Operation Inherent Resolve (CJTF–OIR) anti-ISIL coalition provided extensive air support while SDF personnel composed the majority of the ground forces; OIR special forces and artillery units were also involved in the campaign. The ground campaign stalled and was paused in early 2018 due to the Turkish military operation in Afrin, but resumed on 1 May 2018 with the new phase named by the coalition as Operation Roundup. The third phase began on 10 September 2018 but was halted due to Turkish artillery attacks on SDF positions near the Syria-Turkey border on 31 October. The SDF and the coalition announced the resumption of the offensive on 11 November. After a series of steady successes following the capture of ISIL's Hajin stronghold, and a ten-day pause for civilian evacuations, the SDF launched its final assault on ISIL's final pocket of territory on 9 February 2019 and declared victory on 23 March, concluding the campaign.
Opposition–ISIL conflict during the Syrian Civil War started after fighting erupted between Syrian opposition groups and the Islamic State of Iraq and the Levant (ISIL). In early January 2014, serious clashes between the groups erupted in the north of the country. Opposition groups near Aleppo attacked ISIL in two areas, Atarib and Anadan, which were both strongholds of the fundamentalist Sunni organization. Despite the conflict between ISIL and other rebels, one faction of ISIL has cooperated with the al-Nusra Front and the Green Battalion to combat Hezbollah in the Battle of Qalamoun. By 2018, the Islamic State was destroyed in the territories held by the opposition.
