SF2 SA-14 Gremlin / 9K34 Strela-3 MANPADS Pack 1.0
-------------------------------------------------------------------------------------------------------
This pack features the SA-14 Gremlin. It is a man-portable, shoulder-fired, low-altitude,
infrared guided surface-to-air missile system (MANPADS) developed as a response to
the limited performance of the earlier SA-7 Grail. The missile was largely based on the
earlier Strela-2 and thus development proceeded rapidly.
The most significant change over the Strela-2 was the introduction of an all-new infra-red
homing seeker head. The new seeker worked on FM modulation (con-scan) principle,
which is less vulnerable to jamming and decoy flares than the earlier AM (spin-scan) seekers,
which were easily fooled by flares and even the most primitive infrared jammers. The
new seeker also introduced detector element cooling in the form of a pressurized nitrogen
bottle attached to the launcher.
The effect of cooling was to expand the seeker's lead sulphide detector element's
sensitivity range to longer wavelengths (slightly over 4 µm as opposed to 2.8 µm of
uncooled PbS elements). In practice this made possible the tracking of cooler targets
over longer ranges, and enabled forward-hemisphere engagement of jets under favourable
circumstances. The seeker also had better tracking rate, enabling the missile to track
maneuvering of fast and approaching targets.
A negative side effect from the aforementioned improvements was increased missile
weight, which caused a slight decrease in the kinematic performance compared with
Strela-2M (SA-7B). Against relatively slow, low-altitude battlefield air threats the overall
effectiveness was much improved.
The new system was accepted into service in 1974. Strela-3 missiles have been exported
to over 30 countries.

Known issues:
- System has limited all aspect capability mostly against slow, low-altitude targets.
- Helicopters have higher survival rate per hit because in some cases missiles hit the tail rotor
without causing significant damage. I guess this is another game engine characteristic.
- Low altitude (lower than 500 meters) performance is downgraded for current missile values.
By increasing noise rejection the missile becomes capable of hitting targets in lower altitude
but at the same time the single shot hit/kill probability is being increased to an unrealistic level.
- Fuze distances are longer compared with the actual lethal and damage radius of the system.
In SF2 world the real high explosive warhead quantity is big enough to destroy a fighter size
target even in 10 meters!

As always open readme.txt first to see installation instructions and credits.
Lot of research and hard work was made to make this SAM as realistic as possible.
More than 2000 launches took place during testing!
Enjoy as much as you can this mod and leave comments with your in-game experience
in the support topic!
