During the VietNam War the Russians provided pilots, equipment and training to the NVA and VietCong on how to shoot down U.S. military aircraft and they were effective.
Since the break up of the Soviet Union there are thousands of former KGB and Russian military specialists all over the world employed in such roles today.
I always wanted to shoot a LAW. Maybe take out a vacant SUV when its grazing.. I hate long shots. Personal is better. ;-)
Personally, I hope we crunch some nuts and soon or the friendly skies will be few and far between in the middle east.
