Would a chopper go down if it was hit by a rpg missile?

Yes, a helicopter could go down if it were hit by an RPG (Rocket-Propelled Grenade) missile, depending on the impact location and the extent of damage. RPGs are designed to penetrate armor and can cause significant damage to critical components like the rotor systems or fuel tanks. However, some helicopters may have defensive measures or armor that could mitigate the effects, but a direct hit is likely to be catastrophic. Ultimately, the outcome would depend on various factors, including the type of helicopter and the RPG's specific design.
