BM-21 Grad

BM-21 Grad is a Soviet 122 mm truck-mounted multiple rocket launcher that became one of the most recognizable rocket-artillery systems of the Cold War. It entered the field as a mobile area-fire weapon, emphasizing salvo volume, simple mechanics, and rapid displacement. Its enduring relevance comes from the huge number of systems, rockets, copies, and derivatives distributed across many armies.

The Grad concept is straightforward: a wheeled truck carries a large bank of launch tubes that can deliver a rapid salvo against area targets. It is not a precision weapon in its original form, but it can saturate positions, logistics nodes, and assembly areas. The truck chassis gives it tactical mobility, while the reload cycle and exposure after firing shape how crews use shoot-and-scoot tactics.

Grad remains important because legacy rocket artillery still shapes contemporary conflicts, especially where forces need inexpensive area fires. Modern users may pair old launchers with newer rockets, fire-control aids, drones, or dispersed operating methods, but the basic tradeoff remains: high volume and availability in exchange for limited precision. That makes BM-21 a baseline system for comparing later MRL developments.
