To those making sexual definitions about this, you are the most retarded dudes I have ever met. A Chinook is a heavy, dual rotored transport helicopter that has a top speed that is almost 200 MPH. Primary use is to transport infantry and/or vehicles. In Call of duty they have replaced the little bird helicopters for the care package delivery. it is slower and is a bigger target in BO so one can shoot it down and steal the package.
*random black ops game*
Me: aw yeah, got the care package
enemy: *shoots down chinook*
Me: you son of a bitch!
