People's Defense Units

The People's Defense Units (YPG), (YPG) ; ar, وحدات حماية الشعب, Waḥdāt Ḥimāyat aš-Šaʽb) also called People's Protection Units, is a mainly-Kurdish militia in Syria and the primary component of the Syrian Democratic Forces (SDF).

The YPG mostly consists of ethnic Kurds, but also includes Arabs and foreign volunteers; it is closely allied to the Syriac Military Council, an Assyrian militia. The YPG was formed in 2011. It expanded rapidly in the Syrian Civil War and came to predominate over other armed Syrian Kurdish groups. A sister militia, the Women's Protection Units (YPJ), fights alongside them. The YPG is active in the Autonomous Administration of North and East Syria (Rojava), particularly in its Kurdish regions.

In early 2015, the group won a major victory over the so-called Islamic State (IS) during the siege of Kobanî, where the YPG began to receive air and ground support from the United States and other Combined Joint Task Force – Operation Inherent Resolve militaries. Since then, the YPG has primarily fought against IS, as well as on occasion fighting other Syrian rebel groups and the Turkish Armed Forces. In late 2015, the YPG became part of the SDF, an umbrella group intended to better incorporate Arabs and minorities into the war effort. In 2016–2017, the SDF's Raqqa campaign led to the liberation of the city of Raqqa, the Islamic State's ''de facto'' capital. Several western sources have described the YPG as the "most effective" force in fighting IS in Syria. Finland and Sweden’s alleged support for the YPG, is one of the points which caused Turkey to oppose Finland and Sweden’s NATO accession bid.

According to Turkey, and Qatar the YPG is a terrorist organization, closely associated with the Kurdistan Workers' Party (PKK), which is listed as a terrorist organization. The flag of the YPG is also a banned symbol in Germany as per Strafgesetzbuch section 86a, although the organization itself is not recognised as terrorist. The Turkish terror classification is not shared by key international bodies in the fight against the Islamic State in which the YPG takes part. Due to this Turkish view, US Army Special Operations Commander General Raymond Thomas suggested the YPG to change their name, after which the name of the Syrian Democratic Forces (SDF) was found.

A light infantry force, the YPG has limited military equipment and few armoured vehicles. According to the Turkish state-run Anadolu Agency, the US military provided US$715 millions in weapons and equipment aid to the political party Democratic Union Party (PYD) and YPG. Amongst the heavy weaponry provided are TOW American anti-tank missiles.

Early origins

Kurdish youth attempted to unify themselves following the 2004 Qamishli riots. The riots began as clashes between rivaling football fans before taking a political turn, with Arab fans raising pictures of Saddam Hussein while the Kurdish fans reportedly proclaimed "We will sacrifice our lives for Bush". This resulted in clashes between the two groups who attacked each other with sticks, stones and knives. Government security forces entered the city to quell the riot, firing at the crowds. The riots resulted in around 36 dead, most of them Kurds.

They did not, however, emerge as a significant force until the Syrian civil war erupted in 2011.

Establishment

The self-defence committees that were to become the YPG were formed in July and August 2011 as the Self Protection units (YXG).

Existing underground Kurdish political parties, the Democratic Union Party (PYD) and the Kurdish National Council (KNC), joined to form the Kurdish Supreme Committee (KSC) and established the People's Protection Units (YPG) militia to defend Kurdish-inhabited areas in northern Syria, i.e. Syrian Kurdistan and the Kurdish enclave of Sheikh Maqsood in Aleppo. Originally a wholly Kurdish force, the YPG began to recruit Arabs from at least 2012.

Control of Kurdish areas

In July 2012, the YPG had a standoff with Syrian government forces in the Kurdish city of Kobanî and the surrounding areas. After negotiations, government forces withdrew and the YPG took control of Kobanî, Amuda, and Afrin.

By December 2012, it had expanded to eight brigades, which were formed in Qamishlo, Kobanî, and Ras al-Ayn (Serê Kaniyê), and in the districts of Afrin, al-Malikiyah, and al-Bab.

Late 2012: Islamist attacks make YPG dominant

The YPG did not initially take an offensive posture in the Syrian Civil War. Aiming mostly to defend Kurdish-majority areas, it avoided engaging Syrian government forces, which still controlled several enclaves in Kurdish territory. The YPG changed this policy when Ras al-Ayn was taken by the al-Qaeda-affiliated al-Nusra Front. At first the YPG conquered the surrounding government-controlled areas: al-Darbasiyah (Kurdish: Dirbêsî), Tel Tamer and al-Malikiyah (Kurdish: Dêrika Hemko). The subsequent Battle of Ras al-Ayn started in earnest when on 19 November 2012, the al-Nusra Front and a second al-Qaeda affiliate, Ghuraba al-Sham, attacked Kurdish positions in the town. The battle ended with a YPG victory in July 2013.

While many rebel groups clashed with the YPG, jihadist and Salafist groups did so the most often. The YPG proved to be the only Kurdish militia able to effectively resist the fundamentalists. While the YPG protected the Kurdish communities it was able to extract a price: it prevented the emergence of new, rival militias and forced existing ones to cooperate with or join the YPG forces on its terms. This was how the Islamist attacks enabled the YPG to unite the Syrian Kurds under its banner and caused it to become the de facto army of the Syrian Kurds.

2013: Kurdish control of al-Yaarubiyah/Til Koçer

In October 2013, YPG fighters took control of al-Yaarubiyah (Til Koçer) following intense clashes with IS. The clashes lasted about three days, with the Til Koçer border gate to Iraq being taken in a major offensive launched on the night of 24 October. PYD leader Salih Muslim told Stêrk TV that this success created an alternative against efforts to hold the territory under embargo, referring to the fact that the other border crossings with Iraq led to areas controlled by the Kurdistan Regional Government, while al-Yaarubiyah led to areas controlled by the Iraqi central government.

2014: Fight against IS

In 2014, the Syriac Military Council, a group of Assyrian units, was formally integrated into the YPG's command structure.

The inter-rebel conflict during the Syrian Civil War led to open war between the Free Syrian Army and IS in January 2014. The YPG collaborated with FSA groups to fight IS in Raqqa province; the group also formed an operations room with multiple FSA factions, called Euphrates Volcano. However, the general outcome of this campaign was a massive advance by IS, which effectively separated the eastern part of Rojava from the main force of FSA rebels. IS followed up on its success by attacking the YPG and the FSA in Kobanî Canton in March and fighting its way to the gates of the city of Kobanî in September. The actual siege of Kobanî approximately coincided with an escalation in the American-led intervention in Syria. This intervention had started with aiding the FSA against the government, but when the FSA was getting defeated by IS in eastern Syria, it escalated to bombing IS on Syrian territory.

With the world fearing another massacre in Kobanî, American support increased substantially. The US gave intense close air support to the YPG, and in doing so, started military cooperation with one of the factions. While it expected that IS would quickly crush the YPG and the FSA, this alliance was not considered a problem for the US. The YPG won the battle in early 2015.

Meanwhile, the situation had been stable in Afrin and Aleppo. The fight between the FSA and IS had led to a normalization in the relations between FSA and YPG since the end of 2013. In February 2015, the YPG signed a judicial agreement with the Levant Front in Aleppo.

Spring 2015: Offensive operations with coalition support

The YPG was able and willing to offensively engage and put pressure on IS and had built up a track record as a reliable military partner of the US. In 2015, the YPG began its advance on Tel Abyad, a move they have planned for since November 2013. With American close air support, offensives near Hasakah and from Hasakah westward culminated in the conquest of Tell Abyad, linking up Kobanî with Hasakah in July 2015. With the capture of Tell Abyad, the YPG has also broken a major supply route of fighters and goods for the Islamic State.

With these offensives, the YPG had begun to make advances into areas that did not always have a Kurdish majority. When the YPG and the FSA entered the border town of Tell Abyad in June 2015, parts of the population fled the intense fighting and the airstrikes.

Autumn 2015: foundation of the SDF

The Syrian Democratic Forces was established in Hasakah on 11 October 2015. It has its origins in the YPG-FSA collaboration against IS, which had previously led to the establishment of the Euphrates Volcano joint operations room in 2014. Many of the partners are the same, and even the logo / flag with the Blue Euphrates symbol has common traits with that of Euphrates Volcano. The primary difference is that Euphrates Volcano was limited to coordinating the activities of independent Kurdish and Arab groups, while the SDF is a single organisation made up of Kurds, Arabs, and Assyrians.

The first success of the SDF was the capture of the strategic ethnically Arab town of al-Hawl from IS during the al-Hawl offensive in November 2015. This was followed in December by the Tishrin Dam offensive. The dam was captured on 26 December. Participating forces included the YPG, the FSA group Army of Revolutionaries, the tribal group al-Sanadid Forces and the Assyrian Syriac Military Council. The coalition had some heavy weapons and was supported by intense US led airstrikes. The capture of the hydroelectric dam also had positive effects on the economy of Rojava.

2016

In February, the YPG-led SDF launched the al-Shaddadi offensive, followed by the Manbij offensive in May, and the Raqqa and Aleppo offensives in November. These operations extended SDF-controlled territory, usually at IS's expense.

On 7 April 2016, the Kurdish neighborhood of Sheikh Maqsood in Aleppo was shelled with mortars that may have contained chemical agents (160 killed or wounded). Spokesperson for the YPG said that Saudi Arabia-backed Jaysh al-Islam (Army of Islam) rebel group has attacked the Kurdish neighborhood of Aleppo with "forbidden weapons" many times since the war's start.

2018: Turkish military intervention

Women's Protection Units

The Women's Protection Units (YPJ), also known as the Women's Defense Units, is the YPG's female brigade, which was set up in 2012. Kurdish media have said that YPJ troops became vital during the siege of Kobanî. Consisting of approximately 20,000 fighters, they make up around 40% of the YPG.

Units

In 2017, the YPG began to form units called regiments in translation, though they are smaller than comparable units in standard militaries:

Tactics

According to a report in IHS Jane's regarding the YPG,

The YPG relies heavily on snipers and backs them by suppressing enemy fire using mobile heavy machine guns. It also uses roadside bombs to prevent outflanking maneuvers, particularly at night. Its lines have generally held when attacked by Islamic State (IS) forces who have better equipment, including helmets and body armor.

The YPG and People's Defense Forces (HPG) have also trained and equipped more than 1,000 Yazidis, who operate in the Mount Sinjar area as local defense units under their supervision.

The YPG calls itself a people's army, and therefore appoints officers by internal elections.

A 20-year-old female YPJ fighter named Zlukh Hamo (Nom de guerre: Avesta Khabur) was reported to have carried out a suicide attack towards Turkish troops and a tank during the early phase of the Afrin Offensive, killing herself and several soldiers in the process. The attack was commended by pro-SDF sources as a courageous attack against a tank using explosives, which killed her in the process.

Equipment

Compared to other factions engaged in the Syrian Civil war, the YPG has not received significant foreign assistance in the form of weapons and military equipment. According to the YPG, circumstances led to their capture of less equipment from the Syrian Army than other opposition groups did. The figures are estimates only based on the balance sheet that the YPG regularly publishes of its activities.

International outreach

Foreign volunteers

Ex–U.S. Army soldier Jordan Matson was among the first foreign volunteers of the YPG. Injured by an IS suicide bomb, he developed the "Lions of Rojava" recruitment campaign for foreign volunteers, launched on 21 October 2014 on Facebook. More than 400 volunteers from Europe, the Americas and Australia have joined the YPG , including at least ten U.S. volunteers, three of which were U.S. Army veterans. People from both China and the Chinese diaspora have also joined.

Other prominent foreign volunteers have included Brace Belden, Macer Gifford, Ryan Lock, Michael Israel, Nazzarno Tassone, Dean Evans, Jac Holmes, Konstandinos Erik Scurfield, Anna Campbell, Lorenzo Orsetti and Haukur Hilmarsson.

Dozens of non-Kurdish Turks (from both Turkey and the European diaspora) have also joined. The Turkish Marxist-Leninist Communist Party (MLKP) has been sending volunteers to fight in the YPG since 2012. At least four have been killed in battle as of February 2015—one during the Battle of Ras al-Ayn and three during the siege of Kobanî. The party released a video in late January 2015 showing several Spanish- and German-speaking volunteers from Europe among its ranks in Jazira Canton; they were reorganised into the International Freedom Battalion on 10 June 2015.

Deaths

During the fight against IS and the defense of Afrin against the Turkish state, several of the international volunteers were wounded and killed. The Icelandic Haukur Hilmarsson, aged 31, was killed on 24 February 2018 in an artillery attack by the Turkish army in the village of Mabeta, Afrin. As a YPJ fighter, the British woman Anna Campbell, 26, from Lewes in East Sussex, was killed in a Turkish airstrike in Afrin on 15 March 2018. In the battle of Al-Baghuz Fawqani, an Italian man fighting for the YPG, Lorenzo Orsetti, was killed on Sunday, 17 March 2019.

Politics

While most countries do not object in principle to their citizens joining the ranks of the YPG, Turkey has been vocal against YPG's foreign recruits.

Several Australians, including former trade unionist and politician Matthew Gardiner, have been involved with the YPG despite threats by Australia to prosecute any citizens involved in the Syrian Civil War. Under Australian law it is a criminal offence to fight with any side in a foreign conflict.

In 2017, Turkish court sentenced two Czech nationals to more than six years in prison for their reported ties to the YPG. In Germany, the YPG leads to controversies as it is up to the police to begin a prosecution for showing a YPG flag. In the state of Bavaria, fines for showing a YPG flag were issued, while the federal government declares that the YPG is not forbidden.

Foreign government support

Because the YPG operates in a landlocked territory, rival opposition groups as well as the Turkish and Syrian government were able to physically prevent foreign aid from reaching it. The YPG's seizure of Til Koçer in October 2013 (cf. above) created an overland connection to more or less friendly groups in Iraq, but could not change the even more fundamental problem, that the YPG had no allies willing to provide equipment.

United States

In August 2014 Mazlum Kobanî led negotiations with the US in Sulaymaniya, which led to a military alliance against IS. The United States provided the YPG with air support during the siege of Kobanî and during later campaigns, helping the YPG defend territory against attacks by the Islamic State. Turkey has criticised US support.

The YPG also received 27 bundles totalling 24 tons of small arms and ammunition and 10 tons of medical supplies from the United States and Iraqi Kurdistan during the siege of Kobanî.

On 11 October 2015, the US began an operation to airdrop 120 tons of military supplies to the YPG and its local Arab and Turkmen allies to fight IS north of Raqqa. The first airdrop consisted of 112 pallets of ammunition and "other items like hand grenades", totaling 50 tons. However, statements from the US that the aid did not contain TOW's or anti-aircraft weapons made it clear that the U.S. continued to have serious regard for the interests of Turkey, which has warned against continued US support for the YPG. On the other hand, the US also supported Islamist rebel groups who fought the YPG. During the Battle of Aleppo, the US-backed Mountain Hawks Brigade battled the YPG and the Army of Revolutionaries for control of the village of Maryamin.

US aid to the YPG continued in late October with the deployment of up to 50 US special forces to assist the YPG, and an enhanced air campaign to support the YPG and local militia groups in their fight against IS. Review of ''Out of Nowhere: The Kurds of Syria in Peace and War'', by Michael M. Gunter. Some of these special forces participated in the al-Shaddadi offensive (2016) and coordinated airstrikes against IS.

During the Battle of Tabqa (2017), YPG special forces were equipped with US-supplied combat helmets, AN/PVS-7 night vision devices, flashlights, and were armed with M4 carbines equipped with AN/PEQ-2 laser sights, holographic weapon sights, and STANAG magazines.

On 9 May 2017, it was announced by the Pentagon that American President Donald Trump approved of a plan that would have the United States directly provide heavy armaments to the major SDF component group, the YPG; the plan comes before a planned final offensive to capture Raqqa from IS.

Russia

With Russia's entrance into the war in late 2015 backing the Syrian government, some reports
