A bulk of North Korean ground-based firepower is tied up in self-propelled, towed and rocket-projected artillery systems. The M-1991 falls into the Multiple Launch Rocket System (MLRS) class of weapons and has been in service since the late-1980s / early-1990s. Inspired by the truck-based rocket projecting vehicles of the Soviet-era, the M-1991 is a locally-produced wheeled system and marks one of the farther-reaching rocket launchers in North Korean Army service.

The M-1991 succeeded the M-1985 series vehicles. It utilizes a 6x6 heavy-duty military-grade truck chassis complete with enclosed forward cab. Over the rear of the vehicle is set the launching component atop a trainable mounting. 22 x 240mm battlefield rockets (surface-to-surface) are set in a three-layered tube arrangement on this launcher. Each rocket can be equipped with various warheads to suit a specific battlefield role. The standard fitting is a High-Explosive, FRAGmentation (HE-FRAG) form suitable for use against "soft" targets like troop concentrations and light-armored vehicles. Alternatively, the warhead may take the form of chemical or incendiary to produce nastier effects upon the recipients.

The rockets hold a range from 40 to 60 kilometers with the launcher able to clear the 22 rocket load in just forty-four seconds. This makes the M-1991 one of the more potent rocket assault vehicles in the North Korean inventory behind the KN-09 series.

The truck-based chassis provides some off-road mobility and good ground clearance but holds origins in a Cold War design of foreign origination. A diesel-fueled unit powers the three axles and provides a road speed maximum of 80 kmh with a road range out to 800 kilometers. Fording is possible up to 1.2 meter depths due to the vehicle's inherently high stance.
