A chinook is a major target and a slow one at that. Lucky shot.
I live close to a Chinook base. As it turns out they are cycling today. I got to thinking when I was watering the garden just how easy would it be to take one down. I shouldered my shovel and tracked one from lift off (1.1 miles away) to passing 500 yards away from me at full speed and about 1,000 elevation. 500 yards is easily within the improved RPG range in an arc.
Quite frankly piece of cake with an RPG. Heck a Ma Deuce would do it easily. Even a lucky shot with a 30-06 could cause damage. Helos are very fragile - even the “armored” ones.
While hovering yes, but Chinooks are actually the fastest chopper in the Army inventory, with a higher rated max speed than either an Apache or a Blackhawk.
