You are completely wrong about choppers. We are all aware about the types of choppers that India possess.
NOW how IGNORANT ARE YOU,that you aren't EVEN AWARE THAT YOUR CHOPPERS MAKE A LOT OF NOISE, specially the Russian ones.
We in DHAKA,from Sitting inside our Apartments,hear and can see these choppers almost ON a daily basis ,flying training sorties ,And can exactly determine the exact type,ONLY BY THEIR ENGINE NOISE/ROTORS, whether its made in the. US-BELLS,RUSSIAN MI SERIES OR FRENCH MADE ONES.
Choppers are very vulnerable, to EVEN HAND HELD SAMS, AND CAN EASILY BE VISUALLY TRACKED by SPOTTERS.even heavily fortified MI 24/35 are NO EXCEPTIONS,LET ALONE MI 17 SERIES, which WE WE HAVE A LOT.
.
Specially at NIGHT they can be heard from quite A DISTANCE, and often disturbs our peaceful sleep.
WELL IN ANY CASE, WHAT DO WE EXPECT FROM fancy KIDS, SITTINGS BEHIND A KEYBOARD AND TYPING ALL SORTS OF CRAP.
