History
Early history
GROM (Polish: Template:Lang, lit. "thunderbolt") is a special operations unit of the Polish Armed Forces within the Polish Special Forces. The unit was officially formed on 13 July 1990.<ref name="History3">Template:Cite web</ref>
By decision of the Minister of National Defence dated 4 August 1995 (Decision No. 119/MON), the unit assumed the heritage and continues the traditions of the World War II Silent Unseen paratroopers of the Home Army, adopting the corresponding honorific.<ref name="Symbols2">Template:Cite web</ref>
In the late 1980s, following security incidents affecting Polish diplomatic missions, a concept for a dedicated special-operations formation was developed within the Ministry of Interior. On 13 July 1990 the unit was formally established as Military Unit 2305 (JW 2305).
Col. Sławomir Petelicki served as the first commander and oversaw the unit’s initial formation. The early cadre was drawn from professional soldiers with prior special-operations experience. Among these were:
- 1 Batalion Szturmowy from Lubliniec (then known as 1 Pulk Specjalny Komandosów and now known as JW Komandosów)
- 48, 56 and 62 Kompania Specjalna
- 6 Brygada Desantowo-Szturmowa
- Polish Navy divers
- Anti-terrorist units of the Policja
- Mechanised Warfare Officer School in Wrocław
- Reconnaissance units of PAF
The unit has trained and operated alongside allied special-operations forces as part of Poland’s NATO commitments; details of training are not publicly disclosed.
During its first years JW 2305 remained non-public. The unit became widely known in 1994 following its participation in Operation Uphold Democracy in Haiti.
Initially subordinated to the Ministry of Interior, on 1 October 1999 the unit was transferred to the Ministry of National Defence and incorporated into the Polish Armed Forces. Today JW GROM forms part of the Polish Special Forces.
Balkans (1996–2001)
In the late 1990s and early 2000s, elements of JW GROM deployed to the Balkans as part of multinational efforts to detain indicted war crimes suspects and support stabilisation missions. On 27 June 1997, during Operation "Little Flower", a mixed team operating under the authority of the International Criminal Tribunal for the former Yugoslavia apprehended Slavko Dokmanović, the former mayor of Vukovar, who was under sealed indictment; he was subsequently transferred to The Hague.<ref name="ICTY1997">Template:Cite press release</ref><ref name="OSWLittleFlower">Template:Cite web</ref>
War on Terror
Afghanistan (2002–2004) + Persian Gulf (2002–2003)
Following the 9/11 attacks, a GROM detachment deployed to Afghanistan; the unit’s official record lists operations across the country during 2002–2004 and again in 2007–2013, including the release of more than twenty hostages, force-protection in Bagram and VIP security tasks. In parallel, from 2002 to 2003 GROM teams took part in maritime interdiction operations in the Persian Gulf, boarding vessels as part of enforcement of the UN oil embargo on Iraq.<ref>Template:Cite web; Template:Cite news</ref>
Iraq 2003: offshore oil terminals (KAAOT/ABOT)
For the 2003 invasion of Iraq, GROM formed part of the Naval Special Operations Task Group alongside U.S. Navy SEALs and SWCC. On 20 March 2003, SEAL and Polish special-forces platoons conducted simultaneous takedowns of the Khor al-Amaya (KAAOT) and Al Basrah (ABOT/MABOT) oil terminals, capturing more than 30 prisoners and securing critical infrastructure without firing a shot.<ref>Template:Cite magazine; Template:Cite news</ref>
Iraq 2003: Mukarayin (Mukaysin) hydroelectric dam
In early April 2003, a mixed team of GROM operators and U.S. Navy SEALs secured the Mukarayin (Mukaysin) hydroelectric power plant and dam northeast of Baghdad to prevent its sabotage and flooding of key routes.<ref>Template:Cite web; Template:Cite web</ref>
Iraq 2003–2004: post-invasion direct action
After the initial invasion phase, GROM remained in Iraq conducting special operations in Baghdad and central/northern Iraq, including raids to capture Saddam Hussein’s associates and members of al-Qaeda wanted by coalition partners.<ref>Template:Cite web</ref>
Afghanistan (2007–2013): TF-49
GROM returned to Afghanistan in 2007 as Task Force 49 under ISAF Special Operations Command, conducting direct-action missions and mentoring Afghan units. Operations included hostage-rescue missions (e.g., the 2013 release of MP Fariba Kakar), while the unit also sustained casualties in combat that year.<ref>Template:Cite journal; Template:Cite news; Template:Cite news</ref>
2021 Kabul airlift
During the 2021 Kabul airlift, Polish special forces including GROM supported the evacuation via 44 flights; according to official government figures, more than 1,100 people were evacuated (including 937 Afghan partners), while international tallies put the figure at around 900 evacuees. Those airlifts also included staff of international organisations and allied governments.<ref>Template:Cite web; Template:Cite news</ref>
Training
Candidates for service in JW GROM undergo a multi-stage selection process that includes physical fitness tests, psychological assessment and a demanding field stage (commonly referred to in Polish sources as an "etap górski" or "truth test") designed to assess endurance, resilience and suitability for special-operations service.<ref>Template:Cite web</ref>
GROM training covers a broad range of special-operations skills. According to official materials, operators receive instruction in counter-terrorism and direct-action techniques, airborne insertion (including military parachuting), combat diving and maritime operations, marksmanship and sniper techniques, as well as medical training and close-quarters battle. Units are organised and trained to operate in small teams in which members are cross-trained to cover key roles as required.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>
GROM conducts training with allied special-operations units and participates in multinational exercises. Official information indicates that the unit undertakes specialist maritime training and cooperates with partner navies for certain competencies; public accounts and unit publications further document exchanges with a range of NATO partners.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>
The unit’s internal training system is organised across several specialist streams and qualification phases covering land, maritime and urban/close-quarters tasks. Open-source accounts and public descriptions of GROM’s course structure commonly refer to tactical specialisations sometimes labelled informally as "green", "blue" and "black" streams (representing field, maritime and urban/hostage-rescue specialisations respectively), but the unit’s official publications describe the system more generally as multi-stage training with specialist follow-on courses.<ref>Template:Cite web</ref><ref>Template:Cite web</ref>Template:Clear
Organization
Details of JW GROM’s strength and internal organisation are classified. Open-source descriptions and official publications indicate that the unit is headquartered in Warsaw (Rembertów district), where the command, staff and most support elements are located.<ref>Template:Cite web</ref>
The unit is structured into combat and support sub-units. These include:
- Combat Team A (Zespół Bojowy A) – a land operations element based in Warsaw,
- Combat Team B (Zespół Bojowy B) – a maritime element based in Gdańsk,
- Combat Team C (Zespół Bojowy C) – a third combat element based in Warsaw,
- logistic, intelligence, communications and security sections.<ref>Template:Cite web</ref>
According to unit publications, the organisational model is broadly comparable to that of the British 22nd Special Air Service Regiment or the U.S. Army’s 1st Special Forces Operational Detachment–Delta, with small specialist teams rather than conventional platoons. The smallest operational element is typically a six-man section, grouped into teams and squadrons.<ref>Template:Cite web</ref>
Operators are trained in at least two specialties, such as communications, demolitions, sniping, combat medicine, or breaching (Method of Entry). Support personnel include analysts, EOD specialists, electronic warfare and IT technicians. The unit also fields Joint Terminal Attack Controllers (JTACs), maintains a canine section (Belgian Malinois) and has access to rotary-wing aircraft including UH-60 Black Hawk helicopters.<ref>Template:Cite news</ref>
