人类战争的历史,可说是一部工具的演变史。从弓箭、金属、车轮、火药、蒸汽机、内燃机、飞机、导弹,乃至核能、电脑等,而工具的变革也带动组织、训练、作战等一系列战争形态的巨变。在这诸多器物与所引发的变革中,直升机及以其遂行的空中机动作战,恐怕是20世纪中叶以来最有趣的议题之一。 The history of the human war can be described as the evolution of a tool. From archery, metal, wheels, gunpowder, steam engines, internal combustion engines, aircraft, missiles, and even nuclear energy and computers, the revolution in instruments also brought about a series of dramatic changes in the form of organization, training and operations. Among these many artifacts and the changes that have been triggered, helicopters and their mobile aerial operations are probably one of the most interesting topics since the mid-20th century.
