SF2 SA-7 Grail / 9K32 Strela-2 MANPADS Pack 1.5

-----------------------------------------------------------------------------------------

This pack features the famous SA-7 "Grail". It is a man-portable, shoulder-fired, low-altitude, 
infrared guided surface-to-air missile system (MANPADS). It is widely exported and has 
been in use in nearly every regional conflict since 1969. Despite its operational limitations,
it has been proved quite effective in the hands of tactical armies and rebel groups.
During War of Attrition on 19 August 1969 Egyptian soldiers brought down an Israeli A-4H 
Skyhawk some miles west of the Suez Canal using Strela-2. According to some sources 
this might have been the first successful combat use of any MANPADS in history! 

Following variants are included:

9K32 Strela-2 (SA-7A, 1968) - First variant.

9K32M Strela-2M (SA-7B, 1970) - Improved variant.

------------------------------------------------------------------------------------------

New features:

- Updated missiles data which offer more realistic performance

- Fuze distances have been increased since the SA-7 had lethality limitations after hitting
  a target. Now a target can be hit but it may return back home safely

- New launch effect and sound

------------------------------------------------------------------------------------------

Known issues:

- Due to game engine limitations concering missile guidance, 9M32 (SA-7A) missile's target 
  aspect has been set as Rear 180 despite the fact that in reality it could be fired only at the rear. 
  After massive failed launches it became clear that it was extremely difficult to achieve a single 
  hit by setting 9M32 as Rear 60 even when some other values such as FOV and track rate had 
  been increased. 

- 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 600-800m) 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!

Enjoy as much as you can this mod and leave comments with your in-game experience
in the support topic!

What's New in Version 1.5

Released

Version 1.5 - 24/07/2018

- Missile's performance was dramatically improved. Performance in version 1.0 was very poor
  resulting in limited effectiveness. After extended testing against a large variety of targets the 
  single shot hit probability was increased to 40% and the single shot kill probability was increased 
  to 23%. These numbers refer to aircrafts flying not faster than 400 - 450 kts and are not equipped 
  with flares. Also low altitude performance was improved. System is able to shoot down low speed 
  aircrafts at an altitude of 100m. 

- Missiles carried by each gunner were limited to two. One ready to fire inside the launch tube and 
  another one. That was the real number of missiles carried by tactical army SA-7 gunners according 
  to russian sources.

- New launch effect and sound were added. 


Version 1.0 - 10/03/2018

- Initial release.

It is especially nice to note that after a very simple refinement, this model runs perfectly in the 1st Gens. Thanks!
