In a typical training session, a soldier is placed in a dark room full of figures representing terrorists and hostages. He must then choose the proper silhouette at which to shoot. In another exercise, he is shown a photograph of a target, after which he must burst into a room filled with post-explosion smoke, select the proper target among the many present in the room, and then shoot at it. The GROM is also trained in other operations. It is responsible for protecting strategic state reserves, such as oil drilling platforms in the Baltic Sea.
Members take part in open-sea rescue operations.
They must learn to dive in various conditions and use underwater equipment that does not leave traces on the water surface. GROM operators are the only soldiers in the Polish armed forces to perform free-fall jumps in winter. The GROM must also be prepared to conduct protection, evacuation, and rescue operations outside the country. In fact, its missions outside of Poland have earned it international recognition. The unit was tasked to protect international dignitaries sent to Haiti to implement the democracy restoration program.
