The M202 multishot rocket launcher evolved from XM191 multishot rocket
launcher, that was extensively combat tested by US Army in Vietnam
during late 1970s. The M202 is very similar to XM191 although it
appears that its rockets were loaded with different incendiary agent -
TPA rather than Napalm. It is also believed that XM191 was developed as
a multipurpose weapon, capable of firing not only incendiary, but also
66mm HEAT rockets, compatible wit that of M72 LAW lightweight antitank weapon. The M202, however, was issued only with one type of ammunition - the M74 incendiary rockets. In
theory, the M202 was an impressive weapon with significant combat
capabilities - it had long range (compared to earlier flamethrowers),
it allowed for relatively rapid fire and high maneuverability, its
physical and psychological effect on unprotected infantry and military
vehicles was significant to say the least. However, it appears that
M202 ammunition had some flaws (most probably due to poor quality
control or design flaws), which resulted in self-ignition of warheads
during loading of the weapon. Not surprisingly, such disastrous events
made the M202 less than popular among the troops, and most M202
launchers were put into storage during late 1980s, although some
launchers were observed during training of US and allied troops through
early 1990s. It must be noted that M202 made its biggest impact not
on the battlefields but rather on cinema screens, when it was featured
in the "Commando" movie (1985), starring Arnold Schwarzenegger. In this
movie the M202 was used to blow up the police truck and free the
Schwarzenegger's character, although in real life this would be the
last scene of the action, with main character quickly burned to death
inside scorched truck (the M74 rocket generated fire as hot as 1800-2200oC for several minutes).
The M202
multishot rocket launcher is a four-barreled re-usable smootbore weapon
which is loaded with a clip with factory-loaded M74 rockets, pre-loaded
into separate aluminum tubes that are assembled together to form a
single 4-shot clip. The clip is attached to the rear of the launcher
and each loaded tube forms an extension to the barrel. Once clip is
loaded and fixed to the weapon, launcher can be fired up to 4 times,
with practical rate of fire as high as 1 round per second. Once all
rockets are fired, the empty clip is detached and discarded. During
storage and transportation the M202 launcher is closed at front and
back with two hinged covers, which shall be unlocked and opened before
loading and firing. The front cover has a dual-purpose handle, which is
used for carrying the launcher in vertical position, and is used as a
forward grip in firing position. Firing controls include folding pistol
grip under the barrel cluster, and folding collimating sight on the
left side of the weapon. 66mm rockets use solid fuel engines,
switch-blade type folding stabilizator fins, and a warhead loaded with
some 0.6kg of self-igniting triethylaluminum (TEA), a gel-like
substance. Since the M202 is a rocket launcher, upon firing it produces
a dangerous backblast zone about 15 meters long.
