Military police
The first battalion commander and provost marshal of 6. division Norwegian Army was Maj M Langvik, the current battalion commander is Lieutenant Colonel Jan Henry Norvalls. The battalion consists of approximately 50 officers and NCOs, and 150 privates and corporals. Norwegian MPs first go through a six-month selection/educational period, before being assigned to the battalion or to regimental duties with other units for the remainder of their twelve-month service. Norwegian MPs do not have authority over civilians, except on or in the vicinity of military installations, vehicles or other property or under martial law. They do have authority over military personnel, including in certain circumstances reservists, anywhere, including when such personnel are off duty.
The Heimevernet ("Home Guard") also has MPs in its ranks. Usually each District (regiment) has one or two platoons, consisting exclusively of former regular or conscript military police personnel.
Norwegian MPs wear a red beret and a red lanyard around the left shoulder extending to the left front pocket. Only personnel currently serving as MPs are allowed to wear this. When on official duty, They have previously worn the MP armband, which is black with "MP" in red letters. It was worn on the left shoulder, following NATO practice. Before that it was worn on the right shoulder. They can also wear white webbing, or a number of items for special duties, like high visibility vests for traffic duty, or as mounted personnel while performing motorcycle escort for the Royal Family or their official guests, etc.
Army canine units are also assigned to the MP battalion, but the personnel in such units are not necessarily MPs. Such personnel do not hold military police authority, and do not wear the MP insignia.
MPs have no other powers over civilians than ordinary members of the public, except inside, or in the immediate vicinity of military installations. More serious cases, like narcotics, are handed over to civilian police for investigation.

Poland: The Military Gendarmerie (Żandarmeria Wojskowa, ŻW) are the MPs for the entire Polish military, established in the 1990s.

Portugal: In Portugal, each branch of the Armed Forces has its own military police force. The Portuguese Navy has the Polícia Naval (Naval Police), the Portuguese Army has the Polícia do Exército (Army Police), and the Portuguese Air Force has the Polícia Aérea (Air Police). The Air Police is an arm of its own inside the Air Force, but the Army Police is only a speciality of the cavalry arm and the Naval Police is a unit of the Marine Corps (Fuzileiros). A military criminal investigation police, common for the three branches of Armed Forces, also exists, this being the Polícia Judiciária Militar (Military Judiciary Police), that is under the direct dependency of the Minister of National Defense.
Portugal, also, has a gendarmerie type force, the Guarda Nacional Republicana (GNR, National Republican Guard), that is a special corps of troops that executes both civil public security missions and military missions. In time of peace, GNR is under operational command of the Minister of Internal Affairs, but in time of war it can be put under the command of the Armed Forces. GNR is not tasked with enforcing the law within the Armed Forces.
Included in the Portuguese Navy organization also exist two special police forces. The first one is the Polícia Maritima (Maritime Police), that serves as a coast guard and maritime law enforcement agency in the scope of the civil role of the Portuguese Navy as the National Maritime Authority. The other one is the Polícia dos Estabelecimentos da Marinha (Navy's Establishments Police), a small gendarmerie type agency responsible for guarding the Lisbon Naval Base and some other naval facilities.

Romania: In Romania, the Romanian Military Police (Poliția Militară) carries out police duties for the Romanian Armed Forces. It usually handles military security and military crimes and it has national jurisdiction. The Romanian military police is organized in four battalions (two of them are headquartered in Bucharest, one in Iași and one in Târgu Mureș).
The Romanian Gendarmerie, although a military force with national jurisdiction, is not tasked with enforcing the law within the armed forces (in contrast to the French Gendarmerie, which acts as both military and national police force).

Russia: The Russian Military Police (Военная полиция России) are the MPs for the entire Russian military. They carry out police duties for the Russian Armed Forces.

In April 2012 Chief Military Prosecutor Sergei Fridinsky said Russia's military police will be instituted in two stages: first, the integration of the relevant Defence Ministry services and second, granting the new agency investigative functions. In early February 2014 Russian President Vladimir Putin signed into law the Law on Military Police, the State Duma adopted on 24 January and approved by the Federation Council on 29 January. During consideration of the bill in the lower house of the parliament, presidential envoy to the State Duma Garry Minkh explained that military police has already been created and running, but its activities are governed by departmental orders. President's initiative is aimed at strengthening the legal framework of the forces. On 27 March 2015, Russian President approved the Official Charter of the military police of the Russian Federation.
The Military Police have five main functions:

Maneuver and mobility support operations
Area security operations
Law and order operations
Internment and resettlement operations
Police intelligence operations
The National Guard of Russia and Federal Security Service has its own military police units.

Serbia: The Military Police (Serbian: Војна Полиција, Vojna Policija) are considered to be among the best qualified and most combat-prepared organizations within the Serbian military. Their responsibilities include counterterrorist operations, combating organized crime, close protection, securing hostages and search and rescue.
Specific training is provided for members of special units of the Military Police. Drills for Military Police units, from squad to battalion, are based on their anticipated tactical employment, including training in putting down civil disorder.
The Military Police Directorate of the General Staff of the Serbian Military is responsible for overseeing the units of the Military Police.
Similar units include:

Military Police Battalion Cobra
Military Police Counter-terrorist Battalion

Spain: Each branch of the Spanish Armed Forces (Army, Navy and Air Force) has its own military police (Policía Militar, Policía Naval and Policía Aerea respectively). They are only recognized as constabularies with jurisdiction over military installations, military operations and military personnel. They have jurisdiction over civilians off of military installations like Civil Guard (Spain). They are also in charge of the security of military installations, play a role as bodyguards of generals, admirals and other relevant military personnel, provide security services to military transports and police military personnel abroad. They have the consideration of authority agents.
The Civil Guard (in Spanish Guardia Civil) is the Spanish gendarmerie force. Along with their civilian law enforcement functions, due to their military nature the Civil Guard is also assigned several functions as a Military Police under the Minister of Defence, the most important of which is Criminal Investigations in military facilities and vessels, other MP functions include traffic and customs enforcement in international missions.

Soviet Union: The Soviet Armed Forces did not have any units technically named 'military police'. Two separate agencies handled military police duties on a day-to-day basis.
The Komendantskaya sluzhba or "Commandant's Service" of the Soviet Army wore a yellow letter "K" on a red patch on the sleeve to indicate their membership of this service—the "de facto" army police.
A second organisation called the Traffic Regulators existed within the Rear Services. Traffic Regulators served to control military highway and motor vehicle traffic. Traffic Regulators also wear a white painted helmet with red stripes to indicate their status and either an armband ar patch with the Cyrillic letter "P" (R).
In the Soviet Navy and (later in the present day Russian Navy) the role of Naval provosts was primarily filled by personnel from the Naval Infantry.

Sweden: The Swedish military police are part of the Life Guards, stationed in Stockholm. There are two MP companies, the 14th and the 15th companies. The 14th MP company serve a so-called GSS/T contract (two years of service over a period of eight years, the remaining time the soldiers can have a civilian job or study) and the 15th MP company serve a so-called GSS/K contract (hired continually for eight years). The Life Guards are also the seat of the Swedish military police unit (MP-enheten) which is responsible for the education of new MPs and is in charge of all MP activities in Sweden. Part of 13th security battalion, which is a counter-intelligence battalion, is also part of the Life Guards and has some soldiers who are trained MPs (mostly corporals and sergeants).

Switzerland: In the Swiss Armed Forces, the Military Police is responsible for law enforcement on military property and for all incidents where military personnel or equipment is involved. Unlike, for example, the United States, a military policeman in Switzerland has the same power to arrest any person that has committed an offense he witnessed or if he has reasonable grounds to believe the person has committed a violent offense.
