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 (IS), provoking Turkish involvement in the Syrian Civil War.
The Army of Revolutionaries, also known as 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).
Relations between the People's Protection Units (YPG) and the Free Syrian Army (FSA) are unclear and varied among the different FSA factions. Both are opposed to the Islamic State of Iraq and the Levant. However, several clashes between the two have taken place. Under pressure from the United States, some FSA groups coordinate with the YPG to battle ISIL under the name of the Syrian Democratic Forces, although some other FSA groups remained in conflict with the YPG and the SDF, including FSA groups in the 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 offensive consisted of separate operations in three different areas: Tell Brak, al-Hawl, and the southern al-Hasakah city countryside.
The al-Shaddadi offensive (2016), also known as Operation Wrath of Khabur, was an offensive launched by the Syrian Democratic Forces (SDF) during the Syrian Civil War, in February 2016. 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.
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 northern al-Bab offensive was a military offensive and part of the third phase of Operation Euphrates Shield launched by the Turkish Armed Forces and factions from the Free Syrian Army and allied groups, with the goal of capturing the city of al-Bab located north of Aleppo from the Islamic State of Iraq and the Levant.
The western al-Bab offensive was a multi-sided military confrontation between the Syrian Army, the Syrian Democratic Forces (SDF), other (Turkey-backed) FSA factions, and the Islamic State of Iraq and the Levant in the countryside of northwestern Aleppo Governorate, south of the towns of Mare' and Tel Rifaat.
The Raqqa campaign was a military operation launched in November 2016 during the Rojava–Islamist conflict by the Syrian Democratic Forces (SDF) against the Islamic State of Iraq and the Levant (ISIL) in the Raqqa Governorate, with the goal of isolating and eventually capturing the Islamic State's capital city, Raqqa. The SDF's subsidiary goals included capturing the Tabqa Dam, the nearby city of al-Thawrah, and the Baath Dam further downstream. The campaign ended successfully in October 2017, with the capture of Raqqa.
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 was a Syrian Democratic Forces (SDF) military operation against the Islamic State of Iraq and the Levant (ISIL) to capture and secure the Tabqa Dam, al-Thawrah (al-Tabqah), Tabqa Airbase, and the surrounding countryside during the 2016–2017 Raqqa campaign of the larger Rojava-Islamist conflict of the Syrian civil war. The SDF assault began on 22 March 2017, and resulted in the capture of Tabqa and the Tabqa Dam on 10 May 2017. The SDF was supported by the United States-led CJTF–OIR coalition during the battle.
The battle of Raqqa (2017), also known as the second battle of Raqqa, was the fifth and final phase of the Raqqa campaign (2016–2017) launched by the Syrian Democratic Forces (SDF) against the Islamic State (ISIL) with an aim to seize the city of Raqqa, the de facto capital of ISIL since 2014. The battle began on 6 June 2017, and was supported by airstrikes and ground troops from the US-led coalition. The operation was named the "Great Battle" by the SDF. It concluded on 17 October 2017, with the SDF fully capturing the city of Raqqa.

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 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.
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.
