I would really like to avoid the SAMSIM to be called a "Terrorist Training Tool", and the Shilka is only requiring few people to shot a plane... What a strange idea... Did you believe that cannot be found an ex-Quadafy soldier, to teach them??? C'mon!
And it's a bit space consuming to atach "Shilka" on your suicidal vest...
I believe that on SA-3 "Vozvrat" button didn't work
