Well... Actually in A-stan DShK was a prime killer of Hinds. Mi-24 integral steel armour not exceeds 5 millimeters(sufficient to reliably stop only 7,62mm bullets, if not to consider oblique shots) and partially covers only certain vital areas and systems like cockpit(sides, not belly or front!!!), engines and rotor gearbox. In real life even a well-placed or abnormally lucky burst from old good AKM can make Hind to go down as happened during first Chechen campaign. Survivability issues were only resolved in Mi-28.
