~How well trained must a person be to hit an F-16 at strafing speed with a Stinger?
Are Stingers Laser/Fly-by-wire/IR or just old “Canon EOS”, AKA: point and shoot?~
In fact it is a no-brainer to take out a jet with Stinger or similar East-bloc system.
Especially F-16 which is a single engine after-burning aircraft. It has an ideal thermal signature for such a weaponry to lock-on and it certainly won’t make it after getting a single warhead into engine.
Dedicated groung attack platforms like A-10 or Sukhoi-25 are less vulnerable because they are armored, twin-engine and their motors aren’t burning at such a rate but still Manpads are advanced enough to lock on it and they are slow enough to get multiple hits while loitering over target.
You don't know what you are talking about. Not only are there 3 required operator engagement actions (active, uncage, trigger pull), there are other requirements such as inserting the BCU, getting target lock, super elevation, and lead. These have to be done in the correct order.
Stinger is not a point and trigger pull weapon.
