1.5 History of JW GROM

Among the five special forces units under the Special Troops Command is Grupa Reagowania Operacyjno-Manewrowego, or Group (for) Operational Manoeuvring Response (GROM). It was named after Poland’s elite World War II special operations unit, the Silent Unseen (Cichociemni Spadochroniarze Armii Krajowej), and was inaugurated on July 13, 1990. [Source]

1.5.1 Early History of JW GROM

Officially activated on July 13, 1990, JW GROM undertook a range of special operations and unconventional warfare missions, including anti-terrorist operations and projecting military force deep into enemy territory. The unit was named in honor of the Silent Unseen (Cichociemni Spadochroniarze Armii Krajowej). 

1.5.2  Foundation of JW GROM

In 1989 Jews from the Soviet Union were allowed to emigrate to Israel and Poland was one of several countries which provided help to the organisation of the operation. Dubbed Operation Bridge (Operacja Most)  this created the need for Poland to establish a new special forces unit due to potential targeting by Islamic terrorists. 

Lt. Col Sławomir Petelicki was assigned to create a new special forces unit in 1990. It was established on 13 July 1990 and named after the WW2 “Cichociemni” Polish Home Army Paratroopers. After an agreement between the Ministry of Internal Affairs and the Ministry of Defense, its command fell under the Commander of the Polish Special Forces.


1.5.3 First major military operations of JW GROM (1994-2003)

JW GROM took part in police-type military operations in Haiti in 1994 and from 1996-2001 operators from JW GROM arrested several war criminals in the Balkans including Slavko Dokmanović (The Butcher of Vukovar) during Operation Little Flower. They also took part in missions in Slovenia and Kosovo. 

The unit was also assigned to the inspection of ships in the Persian Gulf from 2002-2003 in support of allied forces. [Source]

1.5.4 Afghan and Iraq War Involvement

Early in 2002, a 40-person JW GROM operator team was sent to Afghanistan to support allied operations there. [Source

Along with US Navy SEALs, British Royal Marines, and US Psy-Ops teams, JW GROM participated in the 2003 invasion of Iraq as a member of the Naval Special Operations Task Group. JW GROM operatives, alongside US Marines from 1st F.A.S.T Company and US Navy SEALs from Teams 8 and 10, seized control of the MABOT oil facility on March 20, 2003. Additionally, they successfully neutralized explosives found within the facility. [Source]

A combined squad of twenty US Navy SEALs from SEAL Team 5 and thirty JW GROM personnel successfully seized control of the Mukatayin hydroelectric dam. There were no casualties on either side during the operation. The only injury occurred when a GROM operator broke his ankle during insertion from a US Air Force MH-53J Pave Low helicopter. [Source]

1.5.5 Task Unit Thunder

After the invasion of Iraq, JW GROM personnel actively joined the CJSOTF-AP (Combined Joint Special Operations Task Force-Arabian Peninsula) and formed the backbone of Task Unit Thunder. Throughout the Iraq War, this force, led by JW GROM operators, spearheaded rapid assaults alongside partner Task Units to target suspected enemy positions and compounds.

Along with Task Unit Raider, which was based on the operators of Marine Corps Special Operations Command Detachment One, Det One, they supplied a Tier-1 counterterrorism unit for the task force. These two task units eventually became the main direct action assets of the CJSOTF-AP. [Source]

The CIA appreciated JW GROM operatives for their reportedly lower engagement threshold when it came to targeting, a characteristic they valued. JW GROM snipers only needed a suspect cell phone call or a curfew breach to engage their targets. [Source]

1.5.6 Chris Kyle 

In September 2004, SEAL operator Chris Kyle joined JW GROM’s B Squad to contribute his sniper and navigator expertise. He commented that 

“The GROMs were a lot like the SEALs: extremely professional on duty and outright revelers at the end of the day. They all drank Polish vodka, and especially Żubrówka.”

He continued by comparing the JW GROM operators to the US Navy SEALs, British SAS, and Special Forces of the US Army. Noting that the manner JW GROM and SEALs attacked houses was very similar, he thought the group’s Polish stun grenades were superior. This was because Polish stun grenades detonated seven times, as opposed to the US stun grenades’ single detonation, providing a more confusing and disorienting experience for the target. [Source]

Unit paramedics are attached to an ambulance crew and sent to some of the most dangerous districts in Warsaw to get used to the sight of blood and wounds. [Source]

Climate and safety of training

JW GROM operators are trained in a variety of different climates. The diversity of Poland’s topography allows for this and they have also participated in training in both Venezuela and the Sahara. 

Training in JW GROM has been reported to be boring as weapons are stored in safes and only brought out for training which is done repeatedly and to improve muscle memory. The basic movements are drilled into the operators to prepare themselves for the potential that they may come across terrorists or opponents using someone as a human shield. [Source]

Hostage Rescue Training

The unit regularly conducts training which is meant to emulate the rescue of hostages from a variety of different environments. This includes planes, buses, trains, buildings and other sites. They also regularly conduct hostage rescue exercises in the ocean and train to rescue hostages from ships, ferries and oil drilling platforms. [Source]

Training levels

JW GROMs training consists of three levels which are green, blue and black. 

  • Green – Green training consists of training which deals with reconnaissance, deep cover sabotage, population extraction/evacuation and the elimination of personal threats
  • Blue – Blue training deals with maritime and naval insertions. Further, this training also includes underwater diving, naval sabotage and naval reconnaissance training. 
  • Black – Black training is the highest level of training for JW GROM operators and includes hostage rescue, VIP protection and area protection

4.1.1 Operations Pre-2000

  • Operation Bridge (Operacja Most) –  The Soviet Union permitted Jews to immigrate to Israel in 1989, and Poland (using JW GROM) was one of the nations that assisted in the operation’s coordination. They transported over 40,000 Jews from the USSR to Israel in 1990-1992. [Source]
