What is the French Foreign Legion?

Reviewed October 2026

Written by Aron, former French Foreign Legion NCO.

The French Foreign Legion is a military force within the French Army, created in 1831 and known for recruiting volunteers from around the world.

What makes the Legion different from most military units is not only the nationality of its soldiers. Men from very different countries, cultures and backgrounds have to learn to live, train and fight together under the same rules. This is why discipline, teamwork and esprit de corps have such an important place in Legion life.

The training is physically demanding, but the pressure is also psychological. New legionnaires have to adapt quickly to military life, learn French and become part of a unit where everyone is expected to work as a team.

Today, the French Foreign Legion remains an operational part of the French Army. Its regiments serve in mainland France, overseas territories and on deployments abroad.

History of the French Foreign Legion

Louis Philippe, the King of the French, created the French Foreign Legion on 10 March 1831. Firstly, recruits included soldiers from the recently disbanded Swiss and German foreign regiments of the Bourbon monarchy. The French expeditionary force that had occupied Algiers in 1830 was in need of reinforcements, therefore the Legion was transferred by sea in detachments from Toulon to Algeria.

The Foreign Legion was primarily used as part of the Armée d’Afrique to protect and expand the French colonial empire during the 19th century.

The FFL also fought in almost all French wars including

• the Franco-Prussian War
• World War I
• and World War II

The French Foreign Legion has remained an important part of the French Army despite major political and military changes in France. It survived three Republics, the Second French Empire, two World Wars, the end of the French colonial empire and the loss of its historical base in Algeria.

Prior to the end of the Algerian War, the legion hadn’t been stationed in mainland France except in wartime. Until 1962, the Foreign Legion headquarters was located in Sidi Bel Abbès, Algeria.

Today, some units of the Legion are in Corsica or overseas possessions (mainly in French Guyana, guarding Guiana Space Centre), while the rest are in the south of mainland France. The current headquarters is in Aubagne, France.

What’s the difference between the French Army and the French Foreign Legion? 

One of the main differences between the French Army and the French Foreign Legion is that the Legion recruits volunteers from many different countries, including French citizens.

The French Foreign Legion is not a separate army and it is not a special forces unit. Its regiments are part of the French Army, although some Legion units have specialized commando elements.

People from more than 140 nationalities serve together in the Legion. Nationality is therefore not normally a barrier to applying, although the recruitment rules can change depending on the international situation.

In 2026, the Legion does not currently recruit Russian or Ukrainian nationals. It also does not accept soldiers or mercenaries who took part in the conflict between Russia and Ukraine. These restrictions are in place until further notice.

Each legionnaire signs a contract “à titre étranger” (on a foreign basis). During his Legion career, he will only be able to serve within French Foreign Legion units and will not be able to transfer to another unit in the French Armed Forces.

Life in the Legion depends a lot on the regiment, the specialty and the period of a legionnaire’s career. Daily life can include training, field exercises, guard duties, courses, deployments and time spent preparing for the next mission. Conditions can be very different between a regiment in mainland France, a deployment overseas or a unit like the 3e REI in French Guiana.

Current operations of the French Foreign Legion

Official Information

The French Foreign Legion is still regularly deployed in France, overseas and on NATO’s eastern flank. Some missions are permanent, while others depend on the regiment and the rotation.

• French Guiana – Operation HARPIE: the 3e REI is permanently engaged against illegal gold mining.
• French Guiana – Operation TITAN: the 3e REI permanently contributes to the protection of the Guiana Space Centre.
• France – Operation SENTINELLE: Legion regiments based in mainland France regularly rotate through domestic protection missions.
• Mayotte and the Mozambique Channel: the 5e RE carries out a permanent sovereignty mission from Mayotte, including a continuous detachment on the Glorieuses Islands.
• Poland – EUMAM Ukraine: France continues to train Ukrainian soldiers in Poland and in France. Legion units can take part depending on the rotation; a company of the 2e REI was deployed in Poland from October 2025 to February 2026.
• Romania – Operation AIGLE: France leads a NATO battlegroup in Romania. Legion units can also be sent there depending on the rotation.
• Estonia – Operation LYNX: France keeps troops in Estonia within NATO’s forward presence. Legion units have regularly taken part, including the 2e REP and the 1er REC.

Legion units also rotate through NATO missions, short deployments and training missions abroad. The regiment changes with each mandate, so the units you see in Poland, Romania or Estonia are not always the same.

Past operations and recent Legion deployments

Sahel – Operations SERVAL and BARKHANE

At the request of the Malian President, France intervened militarily in January 2013. Operation Serval aimed to stop the advance of jihadist forces and help Mali regain control of its territory.

After the elections in 2013 Ibrahim Boubacar Keïta gathered most of the votes and became President of the Republic. In 2015, the non-terrorist rebel groups and the government signed an Agreement for Peace and Reconciliation in Mali. France supported the implementation of this agreement, but Mali formally ended the Algiers Agreement in January 2024.

Operation Barkhane replaced Operation Serval on 1 August 2014. French forces then operated across Mali and the other G5 Sahel countries: Burkina Faso, Mauritania, Niger and Chad.

Operation Barkhane was the main French counter-terrorism operation in the Sahel from 2014 until France ended the operation in 2022. Foreign Legion regiments were repeatedly deployed during Serval and Barkhane, but Barkhane is no longer a current French operation.

Its goal was to help Sahelian forces fight jihadist groups across the region. For the Legion, Serval and Barkhane were major deployments of the last decade.

Lebanon – Operation DAMAN

France is still deployed in Lebanon with Operation Daman as part of UNIFIL. Legion regiments have taken part in this mission many times, but the French units change with each mandate.

A Legion unit can be sent to Lebanon again when it comes up in the rotation.

Poland – EUMAM Ukraine

France is still taking part in EUMAM Ukraine by training Ukrainian soldiers in Poland and in France. From October 2025 to February 2026, a company of the 2e REI was deployed in Poland for this mission. The Legionnaires trained Ukrainian soldiers and came back with lessons the regiment now uses to prepare for high-intensity combat.

France – Operation RÉSILIENCE

Operation Résilience was launched in 2020 during the COVID-19 crisis. Legion units took part in transport, logistics and medical support. The operation has since ended.

Current operations in detail

French Guyana – Operation HARPIE and TITAN

Harpie

Operation Harpie has been active since 2008. In 2026, the 3e REI remains permanently engaged in this mission alongside the Forces armées en Guyane, fighting illegal gold mining and the networks that support it.

Experience

Operation Harpie aims to stop illegal gold mining and reduce its economic, social and environmental impact. The missions take place in difficult conditions because of the distances, the rainforest and the climate. During the rainy season, humidity can reach 90 to 95%, with temperatures around 30°C.

Moving through the jungle with all your equipment is hard. If you didn’t forget anything, you’ll have around 30 kg in your backpack.

Operation Harpie is dangerous. Illegal gold miners can become violent, but the jungle itself is also a major risk. Rivers, mine shafts, tropical diseases and difficult evacuations can quickly turn a mission into a serious situation.

In 2019, three French soldiers died after breathing toxic fumes inside an illegal gold mine. In November 2025, another soldier died while crossing a river during a Harpie mission.

There is also a lot of money involved. In 2025, Harpie operations caused almost €149 million in losses to illegal gold mining networks through seizures and destroyed equipment.

Titan

Operation Titan protects the Guiana Space Centre at Kourou. The 3e REI patrols around the launch site and in the surrounding forest. During a launch, the security is reinforced on the ground, in the air and at sea.

France – Operation SENTINELLE

Operation Sentinelle is one of the regular missions for Legion regiments based in mainland France. Companies rotate through the mission with other Army units to protect sensitive sites and support the security forces when needed.

French Foreign Legion recruitment in 2026

The French Foreign Legion recruits about 1,100 new legionnaires each year. Its official recruitment website reports around 8,000 applications examined annually. Recruitment continues throughout the year, but meeting the minimum requirements does not mean that you will be selected.

In March 2026, the Legion reported around 9,600 serving legionnaires from 144 nationalities. Your nationality alone does not decide the result. Your physical and medical condition, motivation, background, test results and the Legion’s needs all matter during selection.

For more detailed figures, read my French Foreign Legion recruitment in 2026 article. If you are preparing to join, you can also follow my complete joining guide.

The selection process

Volunteers have to pass the selections in a recruitment center, which takes around 3-4 weeks. Once they went through the sport tests, IQ tests, medical tests and interviews, they sign a contract for 5 years. Afterward the recruited volunteers go to Castelnaudary for the four-month basic training, during which they’ll obtain the famous “white cap”, the Képi blanc. The Green Beret remains the Legion’s “battle uniform” headgear. Following the basic training, Legionnaires join one of the 11 regiments of the French Foreign Legion. Regiment assignments depend on training results, medical fitness, available places and the Legion’s needs at the time you finish basic training.
