Scouting, attacking, and transporting people and cargo are the main jobs of military helicopters. Young readers interested in flying machines will find much to like in this addition to Bobby Kalman’s “Vehicles on the Move” series. The who, what, when, where and why are all covered here as young readers learn about the different kinds of military helicopters and the different roles they play in the armed forces. Readers fascinated by flying machines will love the chapters on the parts of the military helicopter and the pilot’s gear, particularly the well-chosen photos used to illustrate both.
