Military districts (also called military regions) are formations of a state's armed forces (often of the Army) which are responsible for a certain area of territory. They are often more responsible for administrative than operational matters, and in countries with conscript forces, often handle parts of the conscription cycle.
Navies have also used a similar model, with organizations such as the United States naval districts. A number of navies in South America used naval districts at various points in time.
This system of territorial organization, adopted shortly after independence, grew out of the wartime wilaya structure and the postwar necessity of subduing antigovernment insurgencies that were based in the various regions. Regional commanders control and administer bases, logistics, and housing, as well as conscript training. However, commanders of army divisions and brigades, air force installations, and naval forces report directly to the Ministry of National Defence and service chiefs of staff on operational matters.

The military regions (originally eleven, then seven) of the People's Liberation Army were divided into military districts (usually contiguous with provinces) and military sub-districts, under the command of the Central Military Commission.
In February 2016, the 7 military regions were changed to 5 theater commands:<ref>Template:Cite web</ref>
Under the Third Republic, a military region comprised several departments which supported an army corps. For many years up to 21 military regions were active.
On 24 July 1873, the French Parliament passed a law which created 18 military regions in metropolitan France.<ref>Musee du Genie, "Le redressement militaire de la France 1871-1914 Cette évocation s’appuie sur les collections du musée du Génie."</ref> A 19th Army Corps was created in Algeria in September 1873 (see Template:Ill). In 1905, the strength of the Troupes coloniales stationed in the 19 military districts of metropolitan France was reported at 2,123 officers and 26,581 other ranks.<ref>Template:Cite book</ref> In 1946, following the Second World War ten military regions were created or recreated, in accordance with a decree of 18 February 1946. They included the 1st (Paris); 2e (Lille); 3e (Rennes); 4e (Bordeaux); 5e (Toulouse); 6e (Metz); 7e (Dijon); 8th (Lyon); the 9th (Marseille), and the 10th in Algeria. The 10th Military Region (France) supervised French Algeria during the Algerian War.<ref>Charles R.

Fifth Republic
With the evolution of administrative organization, France was divided into regional administrative districts (circa 1963) (administrative region dependent of a prefect of the region). The military organisation then combined the administrative organization and in each CAR corresponded a territorial military division (TMD). On the defence side, these military divisions have been grouped into military regions. Their number varied depending on the period. The current number is six.
In the twenty-first century, under the latest thorough reform of the French security and defence sector, there are seven Template:Ill each with a territorial ground army region: Paris (or Île-de-France, HQ in Paris), Nord (HQ in Lille), Ouest (HQ in Rennes), Sud-Ouest (HQ in Bordeaux), Sud (HQ in Marseille), Sud-Est (HQ in Lyon), Est (HQ in Strasbourg).<ref>Code de la défense – Article R1211-4 legifrance.gouv.fr</ref>
Germany
German Reich

From 1919 until 1945, Germany used the system of military districts (Template:Langx) to relieve field commanders of as much administrative work as possible and to provide a regular flow of trained recruits and supplies to the Field Army. The method they adopted was to separate the Field Army (Oberbefehlshaber des Heeres) from the Home Command (Heimatkriegsgebiet) and to entrust the responsibilities of training, conscription, supply and equipment to that command.
The Commander of the Infantry Corps with the identical number also commanded the Wehrkreis in peacetime, but command of the Wehrkreis passed to his second-in command at the outbreak of war.
In peacetime, the Wehrkreis was the home to the Infantry Corps of the same number and all subordinate units of that Corps.
Federal Republic of Germany

Until 2013 the German Armed Forces (Bundeswehr) had four military districts – Wehrbereichskommando (WBK) as part of the Streitkräftebasis or Joint Service Support Command. Each WBK controlled several Landeskommandos (State Commands) due to the federal structure of Germany who have taken over functions carried out by the Verteidigungsbezirkskommandos (VBKs) or Military Region Commands (Defence District Commands) as. These command authorities are in charge of all military facilities. Now the Landeskommmandos are led by the National Territorial Command called Kommando Territoriale Aufgaben der Bundeswehr (KdoTerrAufgBw).
The Indonesian Army operates with military districts, known as Komando Daerah Militer (Military Region Command) abbreviated Kodam. It was created by General Soedirman as a system initially called "Wehrkreise", adapted from the German system during World War II. The system was later ratified in "Surat Perintah Siasat No.1" (No.1 Strategy Command Letter), signed in November 1948.
The Military regional commands function as a means of circle of defense, or regional defense, to defend the designated islands/provinces under Indonesian territory. Each Kodam is commanded by a Major General and has full authority to commence operations with the force under his jurisdiction. The commander (known as Panglima Kodam abbreviated Pangdam) reports to the Chief of Army Staff (KSAD) and is responsible for territorial defence during times of war and development and supervision during times of peace. He is also responsible for ensuring security and protection for VVIP visiting his territory, e.g Presidential visits, etc.
A Regional Command (Template:Langx, Aımaqtyq qolbasshylyq; Template:Langx, Regional'naya komanda) in Kazakhstan operates in a similar fashion to Russian military districts.
The Kazakh Ground Forces
are divided into four regional commands:<ref>Template:Cite web</ref>
Such territorial division provided convenient management of army units, their training and other activities regarding the country's readiness to defend itself.
This increased to 17 military districts of the USSR at the beginning of July 1940 shortly before the USSR was invaded by Germany and entered the Second World War, and were used to create combat Fronts after commencement of the German invasion of the USSR.
During the war the districts were further divided into geographic regions for logistic reasons, these being:Template:Citation needed
North and North Western districts
West and Central USSR districts
South and South Western districts
Siberian and Central Asian districts
Far Eastern districts
After the war, the number was increased to 33 to aid in demobilisation of forces, but by October 1946, they had been reduced to 21.<ref>V.I. Feskov et al, The Soviet Army in the Period of the Cold War, Tomsk, 2004</ref>
By the end of the 1980s, immediately before the dissolution of the Soviet Union, there were sixteen military districts, within three to five main strategic Theatre groupings.

The military district (Template:Langx, usually abbreviated to Milo) was an administrative division of the Swedish Armed Forces, and was a higher regional level subdivision. The commander of a military district, the Militärområdesbefälhavare (also militärbefälhavare), commanded the Swedish Army divisions stationed in the region, the regional naval command, the regional air defence sector as well as the lower regional level subdivision defence districts that made up the military district. The commander answered directly to the Supreme Commander. The military districts in the modern form were created in 1966, and each district was named according to the geographical area they covered. Several changes were made, such as creating or merging districts, until all military districts were disbanded in 2000. After the Defence Act of 2000 the military districts were replaced by new military districts (Template:Langx, usually abbreviated to MD). The new military districts corresponded geographically to the former military districts, however, they did not have the same territorial and operational tasks. In 2005, the military districts were replaced to some extent by four Security and Cooperation Sections (Template:Langx).
In 2013, the Security and Cooperation Sections were replaced by four Military regions (Swedish: Militärregion, MR): Northern, Central, Western and Southern. A fifth military region, Gotland Military Region (Militärregion Gotland, MR G) was formed in 2019.
From 1995, UK commands and later districts were replaced by regenerative divisions. 2nd Division, 4th Division, 5th Division and London District acted as regional commands within the UK reporting to Commander Regional Forces. Scotland District was absorbed by 2nd Division in 2000. The divisions were responsible for training subordinate formations and units under their command for operations in the UK, such as Military Aid to the Civil Community, as well as training units for overseas deployments. 2nd, 4th and 5th Divisions were replaced by Support Command on 1 November 2011.<ref>Charles Heyman, 'The British Army: A Pocket Guide 2012-2013', p.31</ref>

In March 1867, Congress passed the Reconstruction Acts, a series of acts that included the division of the former Confederate States (excluding Tennessee) into five military districts.<ref name="senate">Template:Cite web</ref><ref>Template:Cite web</ref> These districts included:
Each of these districts were governed by former Union Army general officers, and was required to adopt a new state constitution and ratify the 14th Amendment under the Reconstruction Acts in order to rejoin the Union.<ref name="senate" />
