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!

A rotary winged aircraft (helicopter) produced by Boeing/Vertol, it is very distinctive, having two counter rotating rotors rather than the main rotor/tail rotor setup of most helicopters. A powerful heavy-lifter, the first version introduced during 'nam could carry about six tons, the latest versions (e, f) can carry over twelve. The aircraft is designated CH-47. (CH stands for Cargo Helicopter)

The sound of a chinook is very distinctive, like some enormous jackhammer, a penetrating basso thunder that can be heard miles away, and makes the earth shake when the aircraft passes close by.
The platoon was flying into Iraq on a ch47 transport.
