Looking at game data I see :
OOB : Many
(Name : Warhead Size - HE Pen - HE Kill)
Stinger : 4-3-3
OOB 11
Strela-1 : 5-5-5
Strela-2 : 4-2-2
Strela-3 : 4-2-2
Igla-1 : 4-8-8
Igla-V : 4-3-3
Igla-S : 5-4-4
From scanning various web sites I see :
Strela-3 : Warhead 1.17kg, 390g HMX
Igla-1 : Warhead 1.17kg, 390g HMX
Stinger : Warhead 2-3kg, 450g HE
From playing the game I know that on the occasions an aircraft is actually hit by s Stinger they usually take 1-5 damage and once in a blue moon actually get shot down.
Yet various sources say much the same thing :
"The Basic Stinger received worldwide attention during the Afghanistan conflict, when over 250 Russian fixed-wing aircraft and helicopters were destroyed by Mujahideen guerrillas using US-supplied Stingers. Despite limited training, the Mujahideen achieved over 80 per cent combat success with the Stinger missile. To date, the Basic Stinger has been responsible for 270 confirmed kills against both fixed- and rotary-wing aircraft types."

Sooooo . . .
Aside from the apparently semi-random stats given for shoulder launched SAM's it appears (to me anyway) the Stinger is rather dramatically on the low end of the scale where all sources seem to indicate it should be near the high.
