I am pretty much sure that the poster of this thread has concern whether PAF can shot down these UAVs?
*First of all.. these UAVs carry Helfire missiles which has a range of only 8km meaning visual contact could be made easily on them.. *
these UAVs could be shot down by shoulder launched SAM, Anza, Stinger, IR guided or RBS-70 Laser guided...
I am assuming Pakistan (PAF, Army) has most if not all of these technologies available. So not shooting down a drone that is violating Pak air space is more a matter of lack of political will, than an actual inability to shoot them down. Correct?
