Back when I was a youngin, the idea of being directly overflown by a Hind D (big, evil-looking Russian attack helicopter) was a horrifying prospect. Today I was overflown at an altitude of about 100 feet on several occasions by Afghan National Army Hind D’s.
It was vaguely uncomfortable. I knew, on a conscious level, that they were “friendlies,” but all the old aircraft ID classes built in a negative reaction. Something inside me said, “Shoot it! Shooooooot it!”
A 5.56mm rifle will not bring down a Hind D, barring divine intervention.
Sometimes thoughts are just thoughts. Vaguely uncomfortable, but just thoughts.
