The Ochotnicza Rezerwa Milicji Obywatelskiej, ORMO, was created on February 21, 1946, by the State National Council under the auspices of the Communist Polish Workers' Party. It was placed under the control of the Ministry of Public Security led by the tovarishchJakub Berman of the Politburo. The main, initial purpose of ORMO was to provide urgently needed reinforcements to the regular Army, Internal Security Corps and MOspecial forces, during operations against the Polish anti-communist insurgency. The new units were considerably small, made up of 30-300 men armed with rifles and submachine guns. ORMO played a major role in the rigging of the first ever vote in postwar Poland, known as the "3 times yes" referendum. The ORMO men, armed with guns, guarded entrances to all polling stations and expelled official observers, as ordered. They did it again a year later, during the Polish legislative elections of 1947, when they drove opposition candidates out of towns by using intimidation and violence. In total, almost 100,000 functionaries across the country were deployed in order to secure the communist landslide victory in that year. After 1947, the activities of ORMO became more general, shifting from specific political persecution of the regime's opponents, to the public at large. ORMO infiltrated factories and conducted round-ups among shop owners. They confiscated grain and meat from independent farmers, and took part in arresting them as the "enemies of the state", along with regular police. ORMO informants were placed everywhere within the nationalized industry.
Post-Stalinist period
With time, as the political situation in Poland stabilized, postwar submachine guns were replaced with concealed weapons. ORMO men did not receive monthly salaries, but were showered with regular monetary bonuses and state privileges. They were given new apartments, talons for cars, exclusive vacations and access to police health clinics, as well as better job placements. They were thoroughly indoctrinated and feared by the general population. The next widely known operation by the ORMO took place during the March 1968 events, simultaneously in several major cities across Poland. On March 8 – while the regular MO watched students protests passively – ORMO "worker-squads" stormed into the buildings armed with clubs, and performed swarm beatings of students in classrooms, along corridors and at the university halls. Similar operations followed in Kraków, Lublin, Gliwice, Wrocław, Gdańsk and Poznań, against striking students. At least 2,725 people were arrested. The success of the ORMO attack on universities in the wake of growing citizen discontent prompted the Ministry to begin massive expansion of its rank and file. By 1979, ORMO reached over 450,000 members. The nascent Solidarity movement took communists by surprise. By mid-1981 the membership of the Trade Union reached 9.5 million, of the working-age population of Poland. In this case, the ORMO formations weren't used against striking workers because many of its volunteers had become demoralized by public resentment. The show-of-force operations were confined only to major urban centres. The membership dropped dramatically. With the crushing of Solidarity by the 1981 military coup, all special operations were taken over by motorized police, the ZOMO, and SB MSW. Attempts at restructuring ORMO as the Party's own self-defence force failed miserably. In the following years many regional cells were closed down due to a lack of volunteers. Finally, in 1989 ORMO was officially dissolved by the Sejm.
