JW GROM (full name: Jednostka Wojskowa GROM im. Cichociemnych Spadochroniarzy Armii Krajowej, English: Military Unit GROM named in honour of the Silent Unseen of the Home Army) is a Polish special forces unit and forms part of the Special Troops Command of the Polish Armed Forces. The unit's other name is Jednostka Wojskowa 2305 (Military Unit No. 2305). GROM operators gained the nickname of "The Surgeons" due to their extensive medical training and knowledge and their surgical ability to coordinate and execute special operations. GROM was formed in 1990 with training provided to the initial GROM operators by the US Army Delta Force and the British Army Special Air Service. History Early history GROM, which stands for Grupa Reagowania Operacyjno-Manewrowego (English: Group (for) Operational Maneuvering Response), which also means "thunderbolt", is one of five special forces units in the Special Troops Command. It was officially activated on July 13, 1990. It is deployed in a variety of special operations and unconventional warfare roles, including anti-terrorist operations and projection of force behind enemy lines. The unit was named after the Silent Unseen (Polish: Cichociemni Spadochroniarze Armii Krajowej) – Poland's elite World War II special-operations unit. In the 1970s and 1980s, there were several formations of special forces units within Poland, but these were either trained in purely military tasks (sabotage, disruption of communications and such) or in purely counter-terrorist roles. After the Polish embassy in Bern was taken over by a group of four Polish emigrants calling themselves Polish Revolutionary Home Army in 1982, General Edwin Rozłubirski proposed that a clandestine military unit be established to counter the threat from terrorism and other unconventional threats. This proposal, however, was initially rejected by the People's Army of Poland. In 1989, many Jews were allowed to emigrate from the Soviet Union to Israel. Poland was one of the handful of countries that provided aid in the form of organization for the operation, later dubbed Operation Bridge (Operacja Most). After two Polish diplomats were shot in Beirut, Lt. Col. Sławomir Petelicki was sent to Lebanon to secure the transfer of civilians and the Polish diplomatic outposts. Upon his return to Poland, he presented his plan for the creation of a special military unit to the Ministry of Interior, a force that would be trained in special operations to be deployed in the defense of Polish citizens in situations similar to the one in Lebanon.
