English Info about BM21:
The BM-21 Grad (Russian: БМ-21 "Град") is a Soviet truck-mounted
122-mm multiple rocket launcher, developed in the early 1960s. BM stands
for boyevaya mashina, combat vehicle, and the nickname grad means hail. In
the West, the system was initially known as M1964. Several other countries
have copied it or developed similar systems.
The BM-21 122 mm multiple rocket launcher (MRL) system entered service with
the Soviet Army in 1963 to replace the aging 140 mm BM-14 system. It
consists of a Ural-375D six-by-six truck chassis fitted with a bank of 40
launch tubes arranged in a rectangular shape that can be turned away from
the unprotected cab. The vehicle is powered by a water-cooled V-8 180 hp
gasoline engine, has a maximum road speed of 75 km/h, road range of up to
750 kilometers, and can cross fords up to 1.5 m deep. The original vehicle
together with supporting equipment (including the re-supply truck 9T254
with 60 rockets) is referred to by the GRAU index 9K51; the launcher itself
has the industrial index of 2B5. In 1976, the BM-21 was mounted on the
newer Ural-4320 six-by-six army truck.

The crew of five men can emplace the system and have it ready to fire in
three minutes. The crew can fire the rockets from the cab or from a trigger
at the end of a 64-meter cable. All 40 rockets can be away in as little as
20 seconds, but can also be fired individually or in small groups in
several-second intervals. A PG-1M panoramic telescope with K-1 collimator
can be used for sighting. The BM-21 can be packed up and ready to move in
two minutes, which can be necessary when engaged by counter-battery fire.
Reloading is done manually and takes about 10 minutes.
Each 2.87-meter rocket is slowly spun by rifling in its tube as it exits,
which along with its primary fin stabilization keeps it on course. Rockets
armed with high explosive/fragmentation, incendiary, or chemical warheads
can be fired 20 kilometers. Newer high explosive and cargo (used to deliver
anti-personnel or antitank mines) rockets have a range of 30 kilometers and
more. Warheads weigh around 20 kilograms, depending on the type.
The relative accuracy of this system and the number of rockets each vehicle
is able to quickly bring to bear on an enemy target make it effective,
especially at shorter ranges. One battalion of eighteen launchers is able
to deliver 720 rockets in a single volley.
