TheBelgian Armed Forces (Dutch:Defensie;French:La Défense,German:Die Streitkräfte)[3] are the combined national military forces ofBelgium. TheKing of the Belgians is thecommander-in-chief of the Armed Forces. The Belgian Armed Forces was established after Belgiumbecame independent in October 1830. Since then, the Belgian armed forces have fought inWorld War I,World War II, theCold War (Korean War and the Belgianoccupation of the Federal Republic of Germany),Kosovo,Rwanda,Somalia andAfghanistan. The Armed Forces comprise five branches: theBelgian Army, theBelgian Air Force, theBelgian Navy, theBelgian Medical Service and theBelgian Cyber Force.
When Belgium broke away from the Netherlands in 1830 it was initially expected that a neutral buffer state, with its borders guaranteed by France, Britain and Prussia, could avoid the need for an expensive permanent military force, relying instead on the part-time militia of the existingGarde Civique (Civil Guard). The need for a regular army was however soon acknowledged. The basis for recruitment was one of selective conscription under which exemptions could be purchased by obtaining substitutes.[4] In practice this meant that only about a quarter of each year's eligible intake actually served, with the burden falling on the poorer classes.
As part of the national policy of even-handed neutrality, the 19th century Belgian Army was deployed as an essentially defensive force in fortifications facing the Dutch, German and French borders. Mobilisation plans simply required reservists to report to their depots, without arrangements being made in advance for deployment in a particular direction or against a particular enemy. Recruitment difficulties caused the army to remain below its intended strength of 20,000 men, although new legislation in 1868 tightened the basis for conscription. TheFranco-Prussian War of 1870 required full mobilisation for nearly a year, a process which showed up serious training and structural weaknesses. The presence of Belgian forces in strength along the country's borders, supported by intelligence provided by the Belgian civil security service,[5] did however ensure that the combat at no time spilled over into Belgian territory.[6]
As late as the 1890s the Belgian Army still retained a system of selective service, at a time when most European states were moving to a principle of universal obligation, according to the Prussian model. In Belgium conscripts were selected through the drawing of ballots, but individuals could escape service by paying for substitutes.[7] This system favored the well-off and had been discarded elsewhere as inefficient and unpatriotic. For those conscripted the terms of service required eight years in the regular army (of which part might be spent on "unlimited leave"), followed by five years as a reservist. Various categories of volunteer enjoyed such privileges as being able to specify their branch of service, bounties and higher pay.[8]
ThePapal Army based in Rome included from 1860 a battalion-sized unit known as theTirailleurs Franco-Belges (Franco-Belgian Sharpshooters). Recruited amongst volunteers from both countries, this became thePontifical Zouaves in 1861 and fought as an allied force on the French side in 1871 during the Franco-Prussian War.[9]
In 1864 aCorps Expeditionnaire Belge (Belgian Expeditionary Corps) was raised for service in Mexico. Originally intended to serve as the Guard of the Belgian-born Empress Charlotte this 1,500 strong force was largely drawn from volunteers seconded from the Belgian Army. Known popularly as theBelgian Legion, it saw active service in Mexico as part of the Imperial forces, before returning to Belgium for disbandment in March 1867.[10]
From 1885 theForce Publique was established as the military garrison and police force in theBelgian Congo, then under the direct rule ofKing Leopold II. Initially led by a variety of European mercenaries, this colonial force was subsequently officered by Belgian regulars after 1908.[11]
From December 1904 a small detachment of Belgian troops was permanently based in China as the "Guard of the Belgian Legation in Beijing".[12]
Reforms undertaken in the early years of the 20th century included the abolition in 1909 of the system of drawing lots for the selection of the annual intake of conscripts. In 1913, compulsory and universalmilitary service for men was established in Belgium. While this enabled actual peacetime strength to be increased to 33,000 men (increased to 120,500 on mobilisation), this was only sufficient to provide a basis for the creation of seven under-strength divisions (one of cavalry) plus artillery and fortress troops. The Belgian military was also affected by political and popular reliance on the supposedly certain protection of the country's internationally guaranteed neutrality. In the words of the historian Barbara W. Tuchman "the army was considered superfluous and slightly absurd".[13] Training and discipline were slack, equipment inadequate and even field uniforms for active service were old fashioned and impractical.[14]
Although improvements in the Belgian Army had been uneven during the 19th and early 20th centuries, one area of successful reform had been that of increasing the professionalism of the officer corps. The Royal Military Academy had been established in 1834, to be followed by theEcole d'Application for technical training, and theEcole de Guerre for staff training in 1868. The Belgian Army pioneered the practice of training a corps of finance, personnel and general administration specialist officers instead of leaving such functions to civil servants without military experience or inadequately prepared line officers. There was however a serious shortage of trained officers in the rapidly expanding army of 1913.[15]
On the eve of World War I, the Belgian Army comprised 19 infantry regiments (line,Chasseurs à pied,Grenadier andCarabinier), 10 cavalry (Guides,Lancers andChasseurs à cheval) and 8 artillery (mounted, field and fortress). Support forces included engineers,gendarmerie, fortress troops,train andcivil guards. The seven divisions of the Field Army were intended to provide a mobile force while the 65,000 fortress troops provided garrisons for the substantial forts constructed aroundAntwerp,Liège andNamur. These fortifications had been built in several stages beginning in 1859, though a number were still incompleted in 1914. While well-designed and built by 19th century standards, these fixed defences with their sunken artillery turrets had been rendered obsolete by recent advances in heavy siege artillery howitzers.[16]
At the start of World War I in August 1914, the Belgian armed forces were being restructured, due to this measure and the rapid occupation of Belgium only 20% of men were mobilised and incorporated into the armed forces. Ultimately, 350,000 men were incorporated into the Belgian armed forces, although one third of these did not participate directly in combat.
Invaded by surprise by theImperial German Army, which was approximately 600,000 men strong, the small, ill-equipped, 117,000-strong Belgian army succeeded, for ten days, in holding the German army in front ofLiège in 1914. They fought between the emplaced forts in the area and with their support.[17] This strategy was based on the Napoleonic concept of fighting the advance force and preventing a portion of the enemy forces joining the main body. At the time, the authorities and the public celebrated a determined Belgian resistance that the Germans did not expect.
For four years, under the command of KingAlbert I, the Belgian army guarded the important sector of the Allied left wing betweenNieuwpoort, on the coast, andYpres with the help of the forces of theEntente but did not participate in any of the major Allied offensives, which were deemed unnecessarily expensive in terms of cost and manpower by the King of the Belgians.
In 1916,a body of Belgian armoured cars were moved from the IJzer front to help theRussian Empire. The force found itself alongside an identical body sent by the British on theEastern Front.[18]
In Africa a company-sized unit of Belgian colonial troops participated in the occupation of the German colony ofTogoland, TheForce Publique subsequently played a major role in theEast African Campaign against German forces inGerman East Africa, providing over 12,000askaris under Belgian officers for the Allied offensive of February 1916.[19] The most significant Belgian action was the capture ofTabora in September 1916, by a force under the command of GeneralCharles Tombeur.
In Belgium, after four years of war, as of 26 May 1918, the army had 166,000 men of which 141,974 were combatants, forming twelve infantry divisions and one cavalry division. It had 129 aircraft and 952 guns of all calibres. From September, the Belgian army was involved in the Allied offensive until the final victory of 11 November 1918.
After theArmistice with Germany of 1918, the Belgian government sought to retain the strategy of 1914. Little effort was made to acquire tanks and aircraft for the Belgian armed forces, while instead the Government strengthened the fortifications of Liège and Antwerp. This was despite the fact that during World War I the forts had proved ineffective despite strong support from artillery and infantry. Until 1936, Belgium remained allied to France and the United Kingdom.
The Belgian Army underwent a series of reductions from 12 divisions in 1923 to only four after 1926. The rank and file consisted almost entirely of conscripts serving full-time for only 13 months, before entering the reserves.[20]
On 1 September 1939, when theWehrmacht invadedPoland, KingLeopold III of Belgium ordered a general mobilisation, in which 600,000 Belgians were mobilised. Despite warnings from the French and British governments, the King refused an alliance. Belgium was invaded, defeated, and occupied in an18 Days' Campaign after 10 May 1940. Later, 163 Belgian troops were rescued during theDunkirk evacuation, and Belgium's new navy, theCorps de Marine, only reformed in 1939, also participated.
After the defeat in 1940, significant numbers of Belgian soldiers and civilians escaped to Britain to join theBelgian forces in exile.[21] The Belgian government, underHubert Pierlot, evacuated to London where it remained until the liberation in 1944.
Belgian soldiers formed the1st Belgian Infantry Brigade (which also included an artillery battery of soldiers fromLuxembourg) more often known as theBrigade Piron after its commanding officer,Jean-Baptiste Piron. The Brigade Piron was involved in theNormandy Invasion and the battles in France and the Netherlands until liberation.[22]
Belgians also served in British special forces units during the war, forming a troop ofNo.10 Commando which was involved in theItalian Campaign andLandings on Walcheren.[23] The British5th Special Air Service (SAS) was entirely made up of Belgians.[24]
Two Belgian fighter units, the349th and350th Squadrons, were formed in theRoyal Air Force, with over 400 pilots. The 350th Squadron alone claimed over 50 "kills" between its formation in November 1941 and the end of the war.[25]
Twocorvettes and a group ofminesweepers were also operated by the Belgians during theBattle of the Atlantic, numbering some 350 men by 1943.[26] Most military Belgian vessels of the Belgian navy were interned inSpain, except for the patrol craftP16, which managed to escape to the United Kingdom, where it becameHMSKernot.[27]
TheForce Publique also participated in theEast African Campaign and were instrumental to forcing the Italian surrender inAbyssinia.

The harsh lessons ofWorld War II madecollective security a priority for Belgian foreign policy. In March 1948 Belgium signed theTreaty of Brussels, and then joinedNATO in 1948. However the integration of the armed forces into NATO did not begin until after theKorean War, to which Belgium (in co-operation withLuxembourg) sent a detachment known as theBelgian Volunteer Corps for Korea. Later Belgium contributeda corps to NATO'sNorthern Army Group. Defence expenditure grew along with the force size. In 1948 the army was 75,000 strong which grew to 150,000 by 1952.[28] A major defence review in 1952 set a target of three active and two reserve divisions, a 400-aircraft air force and a fifteen-ship navy. Forty anti-aircraft defence battalions were created, linked with radar and a centralised command-and-control system.
As a safeguard against Belgium being invaded again, two major bases,Kitona andKamina, were established in theBelgian Congo. They were almost viewed as a 'national redoubt,' permitting the survival and rebuilding of forces if Belgium were again invaded.[29]
Following a change in government in 1954 conscript service was reduced to 18 months. The Belgian Army gained nuclear capability in the 1950s withHonest John missiles initially and then with nuclear-capable tube artillery. It also adopted the U.S.Pentomic organization, but then switched to a triangular division structure by the early 1960s. Just after independence in the Congo, a Metropolitan Command (Cometro) was active to control the Belgian forces there.[30]
From October 1993 to March 1996, Belgium participated in UNAMIR, a UN Peacekeeping mission meant to end theRwandan genocide. While protecting the Rwandan prime minister, 10 soldiers from the 2nd Commando Battalion were tortured and executed by the Rwandan Presidential Guard. Rwandan Major Bernard Ntuyahaga was later convicted for the murders in 2007.[31][32]
The future of the Belgian armed forces under the leadership of Defence Minister Ludivine Dedonder involves a significant rebuilding and expansion effort. After years of budgetary cuts, Belgium aims to boost its defense budget and capabilities to meet the challenges of a changing security landscape, particularly in the wake of theRussian invasion of Ukraine.
The key aspects of the plan include:
Overall, Dedonder's vision is to ensure that Belgium's defense is well-prepared, adequately funded, and capable of operating within European, NATO, or United Nations frameworks to contribute to collective defense and respond to emerging security challenges effectively.[53]
Since July 2024 the Belgian Armed Forces are structured as follows:
Special Operations Command or SOCOM, does not have direct command over special operations, but is an intermediary center for coordination and communication of special operations between the armed forces components. The command provides advice and expertise and is also tasked with acquisition and distributions of equipment for SOF units. SOCOM is managed by ACOS Readiness and Operations.[54]
Currently, SOCOM is responsible for setting up the new Composite Special Operations Command Center or C-SOCC. This new command center is an international project between Special Operations units of Belgium, The Netherlands and Denmark.[55]
The Belgian Army, Air Force, Medical Services, and Cyber Force all use thesame military ranks. The Navy's ranks are unique in the Belgian Armed Forces.
TheBelgian Army is the ground arm of the Belgian Armed Forces. The Army Commander is Major-General Pierre Gérard.(since 18 October 2019). The Army consists of one staff (COMOPSLAND), one motorized brigade, one special operations regiment supported by an artillery battalion, two engineer battalions and a reconnaissance (ISTAR) battalion. It is also supported by three logistical units, three telecommunication units, four training camps and a center for the training of ground troops.
The Army has around 10,000 troops (as of 2023) and trained for foreign operations in a multinational environment. Around 7500 of them are part of theMotorized Brigade (Belgium) and ~1500 part ofSpecial Operations Regiment (Belgium) and around ~1000 are part of other branches such as military police, Explosive Removal and Destruction Service (DOVO) and more.

TheBelgian Air Force is the air arm of the Belgian Armed Forces. The history of the Belgian Air Force began in 1910 when the Minister of War, General Hellebout, decided after his first flight to acquire aeroplanes. On 5 May 1911 a Farman type 1910 was delivered, followed by a second on 24 May and two other in August of the same year. The air force commander is Major-General aviator Thierry Dupont. (04/07/2023)The air force consists of two fighter aircraft wing, the second tactical wing inFlorennes, operating theF-16 Fighting Falcon and a unit (80 UAV squadron) flying the B-Hunter reconnaissance UAV, the 10 tactical wing inKleine Brogel, operating the F-16 Fighting Falcon, the 15 air transport wing inMelsbroek operating 10Lockheed C-130 Hercules transport aircraft and 2 out of 8Airbus A400M Atlas modern transport aircraft which will replace the C-130s.[58] Two of the new A400Ms are currently operable (CT-01, shared with the Luxembourg Air Force and CT-02),[59] four more are scheduled to arrive in 2021. The 15th Wing also operates a small fleet of troop transport and VIP aircraft. The first wing inBeauvechain operates training aircraft and helicopters (A-109 and NH-90 helicopters). Aside from these flying units, the air force is supported by several support units, such as an air traffic control center, an air defense center (Control and Reporting Center), a meteorological wing and an aviation safety directorate.[60]
TheBelgian Navy is the naval arm of the Belgian Armed Forces. It currently has 1,200 personnel and 10 vessels. The Navy Commander is Rear Admiral Jan De Beurme, since 28 September 2020. Current vessels are:
Frigates:
Minesweepers:
Patrol Boats:
Auxiliary Vessels:
The Medical Services is commanded by aMajor General and is composed of 1,700 active personnel. Providing medical support to all personnel of the Belgium Armed forces, it consists of a Military Hospital and 2 Medical Battalions as well as a Medical Supply Unit.
A Belgian military intelligence service was founded on 1 April 1915. TheBelgian General Information and Security Service, known as ADIV (Dutch) or SGRS (French) and part of the organisational chart of Belgian Defence as ACOS-IS (Assistant Chief of Staff Intelligence and Security) provides security intelligence for the Armed Forces as well as strategic intelligence for the Belgian government. Its focus is on counterespionage.[61]
TheJagers te Paard Battalion (ISTAR) also conducts military intelligence with a tactical goal of preparing and supporting operations abroad.[62]
