The Special Rapid Response Unit or SOBR (Russian – специальные отряды быстрого реагирования = Spetsial'nye Otryady Bystrogo Reagirovaniya), currently known as OMSN (Otryad Militsii Spetsial'nogo Naznacheniya, Special Police Unit), is a spetsnaz unit of the Russian Interior Ministry (MVD). SOBR also continues to exist in Belarus and as of 2006 was headed by Dmitri Pavlichenko.
SOBR units were composed of senior-ranking police officers, better trained than the members of OMON (which is a cross between riot police and paramilitary police), and tasked with SWAT type special operations under the jurisdiction of MVD. They also fought during the wars in Chechnya.
On September 16, 2002, the SOBR was officially dissolved and the SOBR units have been reclassified as OMSN and subordinated to the regional criminal police offices. Due to the popularity of the name, as well as the similarities between SOBR and OMSN, the OMSN is usually still referred to as SOBR by both its officers and civilians alike.
