oye spunk monkey, Russian staff was operating the S400s, not the syrians you idiot! And the usaf and idaf "alien" technology is actually not all that alien, anything they can make, so can europe and China.
And yeah, we see how "high tech" and "well trained" the indian military ranging from the starving soldiers to the air force engineers messing up engine overhauls to the indian navy leaving the "hatch" open on your only nuclear submarine and then going for a dive...
oOoOoOoOoh, I'm scared of the "high tech" and "well trained" indians...
