I wonder if these are the Stinger missiles left over from the Soviet Afghan war. I remember the heat seeking batteries died years ago, that the CIA funded and supplied to the Mujahideen (now Al Qaeda) years ago. Raetheon made them. 600 were unaccounted for when the Soviets left. The media reported about the dead batteries in them.
Doubt it, Saudi Arabia has been giving a ton of manpads to a jihadi group called the “islamic front” which is allied with al nusra the al qaeda front in syria,
Islamic Front is a huge force in syria with 45000-70000 fighters who are on saudi payroll who are allied with al qaeda,dont you think they might share some of those manpads the saudis give them with nusra ?

Of course the white house and most politicans(including republicans)will ever talk about them that might offended our “allies” the saudis.
