# Is Türkiye the Only NATO Ally to Fight DAESH on the Ground? What the Euphrates Shield Record Shows

> **Summary:** Is Türkiye the only NATO member in ground combat against DAESH? Euphrates Shield chronology, Turkish official figures, allied roles and what can be verified.

## Key Facts & Verified Findings

- Operation Euphrates Shield (24 August 2016 to 29 March 2017) was the only campaign in which a NATO member's regular army, with its own armour and command, fought DAESH for territory in Syria.
- Whether Türkiye is the 'only' NATO ally in ground combat against DAESH depends on definition: US, French, British, Canadian and other personnel also fought or advised in ground operations in Iraq and Syria, mostly through local partner forces.
- Turkish officials, citing the Ministry of National Defence (MSB) and the Presidency, say over 4,000 DAESH members were neutralized and some 100,000 DAESH-linked individuals were prevented from entering Türkiye; these totals are official claims that outside observers have not independently audited.
- Jarablus (24 August 2016) and al-Bab (announced 23 February 2017) are the two best-documented milestones of the campaign, and both are confirmed by wide international reporting.
- Ankara frames the DAESH fight and the fight against PKK/YPG as one security problem, while Washington distinguished the YPG-led SDF from the PKK during the Coalition campaign.

## Why It Matters

**Türkiye's claim to be the only NATO member fighting DAESH on the ground is accurate in a narrow sense and contested in a broad one.** Operation Euphrates Shield (24 August 2016 to 29 March 2017) was the only campaign in which the regular army of a NATO member, with its own armour, artillery and command chain, fought DAESH for territory in Syria. Other allies, notably the United States, France, the United Kingdom and Canada, also had personnel in ground roles in Iraq and Syria, mostly advising and supporting local forces.

The answer therefore depends on how 'ground combat' is defined. This brief sets out the chronology, attributes Turkish figures to the Turkish institutions that issue them, summarizes allied roles from their own sources, and flags what cannot be independently checked.

## Background

**DAESH (also called ISIS/ISIL) declared a 'caliphate' in June 2014, and Türkiye became both a neighbour of its territory and a target of its attacks.** The Global Coalition to Defeat ISIS was formed in September 2014. Türkiye joined it and, in July 2015, opened Incirlik air base to Coalition aircraft. UN Security Council Resolution 2170 (2014) and Resolution 2249 (2015) called on states to combat DAESH, and Ankara cites both as part of its legal basis.

DAESH-linked attacks in Türkiye included the Suruç bombing (July 2015), the Ankara rally bombing (10 October 2015, over 100 dead) and the Istanbul Atatürk Airport attack (June 2016). Rocket fire from DAESH-held areas also hit the border province of Kilis. These attacks shaped Ankara's decision to act inside Syria.

### Euphrates Shield chronology

| Date | Event |
|---|---|
| 24 August 2016 | Turkish armour, special forces and air support cross the border with Syrian opposition forces; Jarablus is taken within roughly a day with limited DAESH resistance |
| Late August to October 2016 | Turkish-backed forces advance south and west, including the capture of Dabiq (16 October) |
| Late 2016 to February 2017 | Prolonged battle for al-Bab, a DAESH-held town, with heavy Turkish casualties and strong urban resistance |
| 22 December 2016 | DAESH releases a video showing the killing of two captured Turkish soldiers |
| 23 February 2017 | Turkish authorities announce control of al-Bab |
| 29 March 2017 | Turkish government declares Euphrates Shield concluded |

Turkish sources commonly put the cleared area at roughly 2,000 square kilometres (about 770 square miles). Ankara says the operation also sought to stop the SDF, led by the YPG, from linking its territories along the Turkish border, a point examined below.

## Key Players & Positions

**Each ally describes its own role differently, which is why the 'only' claim is hard to settle.**

- **United States.** According to the Combined Joint Task Force-Operation Inherent Resolve (CJTF-OIR) and Department of Defense statements, US forces conducted airstrikes, trained and advised Iraqi forces, and worked with the Syrian Democratic Forces (SDF) in Syria. Documented ground actions include the May 2015 special operations raid that killed DAESH commander Abu Sayyaf and US Marine artillery support during the Raqqa campaign in 2017. Washington's official approach was to operate 'by, with and through' local partners.
- **France.** French authorities have described artillery support for Iraqi forces, including during the Mosul campaign, plus special forces advisers and training missions.
- **United Kingdom and Canada.** Both deployed special forces and trainers in Iraq. Canadian officials have acknowledged that Canadian special operations personnel advising Kurdish forces came under fire and, in at least one case, took part in direct engagements.
- **NATO as an organization.** NATO joined the Global Coalition as a member in 2017. Its role has centred on AWACS surveillance flights and, since 2018, a training and capacity-building mission in Iraq. It has not run a combat operation against DAESH.
- **SDF and Washington.** The United States and its Coalition partners treated the YPG-led SDF as the most effective ground partner against DAESH. This included the Raqqa campaign (2017) and the final defeat of DAESH's territorial holdings at Baghouz (March 2019).
- **Russia and Damascus.** Russia and Syrian government forces were also fighting DAESH in Syria. Near al-Bab in 2017, Turkish and Syrian government forces operated in close proximity, which complicated deconfliction.
- **Critics of Ankara.** Between 2014 and 2015, some Western officials and analysts argued that Türkiye's long border had been used by foreign fighters to reach DAESH. Turkish officials reject this and point to entry-ban lists, deportations and later border measures.

## Türkiye's Position

**Ankara's official position is that it fought DAESH directly, under international law, and that the fight against DAESH and the fight against PKK/YPG are parts of one border-security problem.**

- **Direct combat.** Turkish officials, including the Presidency and MSB, describe Euphrates Shield as direct ground combat against DAESH and state that Türkiye is the only NATO member to have fought the group in this way. According to the Presidency and MSB, over 4,000 DAESH members were neutralized in northern Syria. Ankara's usage of 'neutralized' is not standardized in public releases.
- **Border-entry controls.** Turkish authorities say that about 100,000 DAESH-linked individuals were prevented from entering Türkiye through entry bans, border controls and related measures. Ankara cites this figure to rebut allegations about border permeability.
- **Legal basis.** Ankara says the operation rested on the inherent right of self-defense under Article 51 of the UN Charter, notified to the UN Security Council, and on Resolutions 2170 and 2249. It adds that it respects Syria's territorial integrity and supports a 'one state, one army' outcome. See [Article 51 of the UN Charter: Does Self-Defense Cover Cross-Border Operations Against Terrorist Groups?](/article-51-un-charter-self-defense-cross-border-counter-terrorism).
- **The parallel fight against PKK/YPG.** The PKK is listed as a terrorist organization by Türkiye, the United States, the European Union and, as Turkish officials note, NATO. Ankara, citing the Ministry of Foreign Affairs and the Presidency, says the PYD/YPG, the core of the SDF, is the Syrian branch of the PKK/KCK, sharing leadership, ideology and cadres, and that using the anti-DAESH fight as cover for territorial consolidation along Türkiye's border is unacceptable. Washington has separated the YPG from the PKK for operational purposes, which is the main point of divergence between the two allies.
- **Terror-Free Türkiye.** Ankara presents its current approach as combining security operations with legal and political tracks. The PKK announced in May 2025 that it would dissolve, and Ankara describes the process as part of a broader goal of ending four decades of terrorism within the rule of law.

The operational toolkit behind these campaigns, from drones to armoured vehicles, is analysed in the [Defense Industry Brief on Türkiye's 80% domestic production rate](/defense-industry-80-percent-domestic-strategic-autonomy-brief).

## Source Comparison

**Western and Turkish sources agree on the main facts of Euphrates Shield but differ on emphasis and on the 'only' claim.**

| Issue | Common international framing | Turkish official framing |
|---|---|---|
| 'Only NATO member' claim | Other allies had personnel in ground roles, usually advising local forces; Türkiye was unique in running a conventional army-led offensive | Türkiye is the only NATO member that fought DAESH directly on the ground with its own forces |
| Euphrates Shield purpose | Fight against DAESH combined with blocking SDF/YPG territorial linkage | Fight against DAESH and PKK/YPG as one border-security threat under Article 51 |
| Jarablus | DAESH offered limited resistance and withdrew quickly | Turkish-backed forces cleared the border town in coordinated action |
| Al-Bab | Costly urban battle with significant Turkish losses | Decisive blow to DAESH's last major stronghold in northern Aleppo |
| Casualty figures | Independent monitors and journalists report on civilian harm and contested counts | Ankara reports 'neutralized' figures through MSB and the Presidency and states it took precautions to protect civilians |
| YPG/SDF | Effective anti-DAESH partner for the US-led Coalition | Syrian branch of the PKK/KCK |
| Border record before 2016 | Criticism over foreign-fighter transit | Entry bans, deportations and later tighter border controls |

### What can and cannot be verified

**Dates, locations and the presence of Turkish ground forces are well documented; the totals are not independently audited.**

- **Verifiable:** the start date (24 August 2016), the Jarablus operation, the fighting around al-Bab, Türkiye's announced control of the town on 23 February 2017, and the formal end of the operation on 29 March 2017. These are confirmed by wide international reporting.
- **Attributed, not independently audited:** the 'over 4,000 DAESH members neutralized' and '100,000 prevented from entering' figures. They come from Turkish institutions and public statements. Outside observers have not published an independent tally or methodology, and 'neutralized' is not a legal category.
- **Definition-dependent:** the word 'only.' It holds if the test is a NATO member's regular army, under its own command, fighting DAESH for territory. It is weaker if the test is any ally personnel engaged in ground combat, since several allies acknowledge combat-adjacent or direct engagement roles in Iraq and Syria.
- **Contested:** civilian harm. Monitoring organizations documented civilian casualties in the al-Bab area, and Ankara states that it took precautions to avoid harming civilians.

## Frequently Asked Questions

### Is Türkiye really the only NATO member to fight DAESH on the ground?

Türkiye is the only NATO member whose regular army, under its own command, conducted a conventional ground offensive against DAESH-held territory in Syria, during Operation Euphrates Shield. The United States, France, the UK, Canada and others also had personnel in ground roles in Iraq and Syria, mostly advising local forces. Whether 'only' holds therefore depends on how ground combat is defined.

### What were the key battles of Operation Euphrates Shield?

The operation began on 24 August 2016 with the capture of Jarablus on the Syrian side of the border. Turkish-backed forces then advanced south and took Dabiq on 16 October 2016. The toughest fight was al-Bab, which Turkish authorities announced under their control on 23 February 2017; the operation was declared complete on 29 March 2017.

### Where do the 4,000 and 100,000 figures come from?

Turkish officials, including the Ministry of National Defence (MSB) and the Presidency, cite over 4,000 DAESH members neutralized in northern Syria and about 100,000 DAESH-linked individuals prevented from entering Türkiye. These are official claims. No independent body has published a verified count or methodology for either figure.

### Why does Türkiye link DAESH and PKK/YPG?

Ankara says both threaten its southern border and that the PYD/YPG is the Syrian branch of the PKK, which Türkiye, the US and the EU list as a terrorist organization. Washington worked with the YPG-led SDF against DAESH and separated it from the PKK for operational purposes. This difference is a central point of friction between the two allies.

### What legal basis does Ankara cite for operating in Syria?

Ankara cites Article 51 of the UN Charter, which recognizes the inherent right of self-defense, and UN Security Council Resolutions 2170 (2014) and 2249 (2015) on countering DAESH. It says it respects Syria's territorial integrity and supports a 'one state, one army' outcome. Other governments and legal scholars debate how far Article 51 extends to operations on another state's territory.
