Origins and Pre-War Structure

• Ukraine's Military Police was formally established by a presidential decree in 2017 as part of the post-2014 defence reforms that restructured the Ukrainian Armed Forces along NATO-compatible lines; before 2017, military law enforcement functions in Ukraine were performed by the Komendatura system (military commandant's offices) inherited from the Soviet armed forces — an administrative mechanism that was not a true professional military police force in the NATO sense; the 2017 reform replaced this with a dedicated Military Police service with professional investigators, patrol capability, and — critically — independence from unit commanders in investigative matters, an independence that the Soviet komendatura system explicitly lacked
• Pre-war organisation: the Military Police was organised under the Ministry of Defence with a Chief of Military Police (Начальник Військової поліції) at the top, territorial military police units in each military district (West, South, North, East, Centre), and garrison MP detachments at major installations; total pre-war strength was approximately 3,000–5,000 personnel — adequate for peacetime garrison law enforcement of a professional army of approximately 200,000, but dramatically insufficient for the wartime military of 800,000+ that Ukraine was building
• Capability development 2017–2022: in the five years between its formal establishment and the full-scale invasion, the Military Police developed investigative capabilities (including criminal investigation departments — DKR, Департамент кримінальних розслідувань — for war crimes, drug offences, and corruption involving military personnel), basic patrol and apprehension capabilities for military personnel in garrison and training areas, a military magistrate system for preliminary criminal proceedings, and liaison relationships with NATO MP units through exercises and exchange programmes; the force was professionalising but had not been tested in wartime conditions

Wartime Expansion

• The full-scale invasion immediately overwhelmed the Military Police's pre-war capacity; the mobilisation of hundreds of thousands of soldiers under wartime conscription — many without prior professional military service, some unwilling, others traumatised — generated disciplinary and enforcement demands that the small pre-war MP force could not begin to address; simultaneously, the geographic expansion of military operations across all of Ukraine's territory required checkpoint and movement control infrastructure across a country of 44 million people at war, which requires an enormous MP manpower investment
• Expansion mechanisms: the Military Police expanded primarily through several channels — dedicated MP candidates selected from military mobilisation pools and given compressed MP-specific training; NCOs and officers from combat units who had demonstrated relevant skills (investigations background, law enforcement civilian experience, physical capability for checkpoint duties) being transferred to MP billets; and the temporary use of regular military personnel under MP supervision for checkpoint duties in non-contested areas where the primary function was administrative rather than enforcement
• By 2023–2024, Military Police strength was assessed at approximately 15,000–25,000 personnel including those in temporary wartime roles; the expansion enabled better geographic coverage but created challenges with professional quality consistency — rapidly trained MP personnel who had never practiced criminal investigation before the war were handling complex cases of alleged desertion, war crimes documentation, and corruption investigations that would challenge experienced detectives in any environment

Checkpoint and Movement Control

• Movement control checkpoints (КПП — контрольно-пропускні пункти) are among the Military Police's most visible and operationally significant wartime functions; checkpoints at roads entering and exiting combat zones, at crossings between military operational areas and civilian population zones, and at major transportation nodes (train stations, bus terminals, port facilities) serve multiple concurrent purposes: verifying that military personnel are authorised to be in their stated location (preventing unauthorised absence), checking documents of civilian vehicles entering restricted military areas, identifying deserters or AWOL personnel attempting to blend into civilian movement, and gathering basic intelligence about traffic patterns that supports force protection planning
• The martial law context: Ukraine has been under martial law since the first hours of the invasion, and martial law grants military authorities including the Military Police expanded powers that do not exist in peacetime; male citizens of military age (18–60) are generally prohibited from leaving Ukraine under martial law; Military Police checkpoints at border crossings and internal boundaries have been a primary enforcement mechanism for this prohibition; the MP role in enforcing the departure prohibition has made it a frequent subject of public controversy, as individual cases of men trying to leave for various humanitarian reasons (family abroad, medical treatment, business necessity) have generated media attention and political debate about the proportionality of the enforcement
• Checkpoint effectiveness and challenges: the scale of Ukraine's territory and the number of roads, waterways, and crossing points that would need to be monitored for effective movement control exceeds the MP's available resources; in practice, checkpoint coverage is concentrated on major roads and crossing points with known significance, and enforcement in remote rural areas is limited; the checkpoint network has been periodically supplemented by Territorial Defence Forces (TDF) personnel in less demanding checkpoint assignments, freeing qualified MP personnel for more complex enforcement duties

Desertion and AWOL Enforcement

• Desertion and unauthorised absence (AWOL — самовільне залишення місця служби) have been the numerically dominant enforcement challenge for the wartime Military Police; Ukrainian media and official military justice data indicate that tens of thousands of cases of unauthorised absence have been opened since the full-scale invasion began; the scale reflects both genuine desertion (soldiers who intentionally and permanently abandon their units with intent not to return) and the broader category of unauthorised absence that includes soldiers who overstay authorised leave, leave without authorisation for family emergencies, or temporarily depart positions without command permission in the chaos of intense combat; Ukrainian law distinguishes these categories with different penalties, and the MP's investigative role is partly to establish which category applies
• The political and social complexity: the enforcement of desertion law in wartime Ukraine has been politically sensitive because the same society that demands military discipline to maintain frontline cohesion also contains families of soldiers who have been at the front for years without rotation, whose mental health and family stability are genuinely under extreme stress; the Military Police is institutionally positioned at the intersection of military necessity (maintaining unit strength and cohesion) and human rights concerns (the treatment of soldiers exhausted beyond their individual capacity to continue); Ukrainian human rights organisations have documented cases where desertion prosecutions appeared to criminalise genuine PTSD-driven behaviour rather than wilful abandonment, and the MP has received both criticism for insufficient enforcement from military commanders and criticism for excessive enforcement from civil society
• Processing and adjudication: the Military Police investigates desertion cases, assembles evidence, and refers cases to military prosecutors and military courts; the military justice system (military prosecutors — військові прокурори — operating under the General Prosecutor's office, and military courts — гарнізонні та апеляційні суди) has faced enormous caseload pressure from the volume of wartime military justice cases; plea arrangements and administrative resolutions (returning AWOL soldiers to units without prosecution in exchange for agreeing to continue service) have been used to manage caseload in cases where the circumstances justified leniency

POW Handling and LOAC

• The Military Police plays a key role in the initial handling of Russian prisoners of war (POW) — the Geneva Convention requires that captured combatants be promptly removed from the combat zone and processed by the capturing party's chain of command, and the MP's role includes initial screening and documentation of captured Russian personnel; the treatment of Russian POWs is not merely a humanitarian obligation but a strategic communication tool and a potential intelligence asset if captured personnel cooperate with tactical questioning
• War crimes investigation: the Military Police Criminal Investigation Department cooperates with civilian prosecutors from the Prosecutor General's War Crimes Unit in documenting potential war crimes committed by Russian forces; MP investigators document physical evidence at liberated sites (mass graves, destroyed civilian infrastructure, evidence of summary executions), collect survivor and witness testimony, and maintain the chain of custody documentation that enables this evidence to be used in criminal proceedings; the scale of this effort — over 130,000 war crimes cases opened by the Ukrainian Prosecutor General — requires massive investigative resources in which MP criminal investigators play a significant supporting role
• Own-force crimes: the Military Police is also responsible for investigating alleged crimes committed by Ukrainian military personnel against civilians, Russian POWs, or fellow soldiers; the institutional importance of this function cannot be overstated for Ukraine's international reputation and legal legitimacy; a military that demonstrably investigates and prosecutes its own personnel for abuse and violations of the laws of armed conflict maintains a qualitatively different relationship with international law than one that ignores such violations; the MP's conduct of these investigations — imperfect under wartime conditions but institutionally genuine — is a significant factor in Ukraine's maintenance of broad Western political support

Unit Discipline and Investigations

• Beyond its enforcement of criminal military law, the Military Police supports unit commanders in maintaining discipline through its presence and investigative authority; the knowledge that an independent MP capacity exists to investigate complaints — against commanders as well as subordinates — modifies the behaviour of military personnel throughout the chain of command in ways that a purely command-internal discipline system does not achieve; a soldier who believes his commander is acting illegally (ordering plunder of civilian property, misusing unit resources for personal enrichment, physically abusing subordinates) has an institutionally independent channel to report through the MP; this accountability function is a basic element of rule-of-law military governance that Ukraine's pre-2014 military lacked
• Corruption investigations: wartime military corruption — misappropriation of military equipment and supplies, fraudulent salaries and allowances, theft of donated equipment — is a persistent challenge in any military system under the pressure of rapid expansion; the Military Police Criminal Investigation Department investigates corruption cases involving military personnel, working alongside civilian anti-corruption institutions (NABU — National Anti-Corruption Bureau; SAP — Specialised Anti-Corruption Prosecutor's Office) on cases that intersect military and civilian jurisdictions; high-profile corruption cases involving military logistics officials, particularly in 2023, demonstrated both the scale of the problem and the institutional capacity to address it through legitimate legal processes
• Relationships with command authority: the MP's operational independence — its authority to investigate officers regardless of rank — creates institutional friction with commanders who may view MP investigations as interference with command prerogative; this tension is inherent in any system of military law enforcement that takes rule-of-law principles seriously; the MP's ability to navigate this tension — maintaining enough independence to be credible investigative institution while sustaining operational cooperation with units that depend on MP support — reflects the professionalism of its leadership and the seriousness of Ukraine's commitment to legitimate military governance

Assessment

• Ukraine's Military Police has developed from a small, newly-formed institution in 2017 to a significant wartime law enforcement and governance organisation that performs functions essential to a rule-of-law military in high-intensity conflict; the rapid expansion has inevitably produced inconsistency in quality, and the wartime caseload has overwhelmed processing capacity in ways that generate legitimate criticism from both military commanders who want faster enforcement and civil society organisations that want more careful due process; these are the tensions of a real institution rather than an ideal one, and the MP's response to criticism — though imperfect — has been generally in the direction of improvement rather than institutional defensiveness
• The war crimes documentation function may be the Military Police's most historically significant wartime contribution; together with civilian prosecutors, the systematic collection, documentation, and preservation of evidence of Russian war crimes creates the legal record that enables eventual accountability — whether through the International Criminal Court (which issued the Putin/Lvova-Belova arrest warrants in March 2023), the proposed Special Tribunal for the Crime of Aggression, or other international mechanisms; this documentation work requires the professional investigative discipline that the Military Police Criminal Investigation Department has developed, and its quality directly affects the eventual accountability outcomes
• Institutional legacy: the Military Police as developed during the full-scale war will be a different and more capable institution than the one that existed before February 2022; the forced adaptation to wartime conditions — however imperfect in execution — has built investigative expertise, checkpoint management capability, and inter-agency coordination capacity that will persist in the post-war Ukrainian military; the institution that emerges from this war will be a more genuine military police force than the pre-war version, shaped by the hardest possible real-world test
