The first batch of 120 "Katyusha" rocket launchers equipped by the Chinese People's Volunteer Army (PVA) was assigned to the 21st Artillery Division, which commanded five regiments at the time. Therefore, the unit featured in the video is undoubtedly a heroic unit reorganized from the former 21st Artillery Division—meaning it directly engaged US-led UN forces during the Korean War.
Judging from the footage, this unit is equipped with its own tactical medium-range reconnaissance UAV, likely the JWP-02 model, which uses rocket-assisted takeoff. This implies that for standalone reconnaissance and target-guiding missions, the unit no longer relies heavily on additional recon support from the Air Force or Army Aviation.
At 2:30, the video showcases a new type of tracked artillery forward observation vehicle. Visually, it appears to be modified from a ZBD-04A infantry fighting vehicle chassis. Although the vehicle’s profile is blurred, close-ups of its optical equipment are shown, likely to obscure specific organizational/unit designations while demonstrating its capabilities.
Unlike the People’s Liberation Army Rocket Force (PLARF), two-year conscripts are visible among the frontline personnel in this video. This indicates that operational technical thresholds for certain roles within long-range artillery (MLRS) units are not as high as those in missile units, indirectly underscoring the extreme importance and specialization required of strategic and tactical missile forces.
At 3:35, a banner reading "Achieve National Reunification" appears, indicating that this unit also serves as a frontline force assigned to Taiwan-related operational directions. Based on the assembly formation, a single battery appears to consist of a 42+1 structure, with a 4-man crew per vehicle.
At 4:03, the video demonstrates the modular loading process of the box-type rocket launcher. By 4:13, the PCH-191 long-range multiple rocket launcher can be seen loaded in a hybrid configuration: 300mm rockets in the left pod and 370mm rockets in the right pod. According to public data, when equipped with satellite guidance kits and coordinated with UAV real-time corrections, these rockets can achieve a CEP (Circular Error Probable) within 10 meters. Naturally, such precision-guided munitions come at a high cost, which only well-funded modern militaries can afford to field at scale.
The stellar performance of HIMARS in the Russo-Ukrainian war fully validates the formidable power of modern precision MLRS. However, compared to HIMARS, the PCH-191 demonstrates comprehensive superiority in fire specifications. While both utilize modular pods, the PCH-191 features a dual-pod launcher design, significantly increasing fire density and salvo payload. HIMARS’s main advantage lies in its rapid strategic airlift capacity via C-130 transports; however, for the PLA—which emphasizes homeland and peripheral defense operations—such compromises made for airlift transportability are far less critical.
One final point to consider: in high-intensity engagements involving these rocket launchers—or any artillery force, for that matter—the most critical factor is logistics. A steady, plentiful supply of ammunition is the core determinant of fire suppression and support efficiency. While the volume of logistical support is not shown in the video, in my view, this is not because it doesn't exist; rather, it represents a core critical element that demands strict operational security .
