After the end of Cold War, the US has involved in several battles such as two Golf Wars, Afghanistan War, and Kosovo War. With the integration of C4ISR system, the model of existing war has been redefined and changed from the traditional type of ¡§force to force¡¨ to the new type of ¡§hide and seek.¡¨ To integrate the new generation of technology in war has become the main objective of each national department of defense in the world. However if we take the lessons of war which mentioned above and think in the opposite direction from the classical theory of war, the basics of high military performance of the US force are not concluded only by the enhancement of high tech weapons. What else are the key issues which influence the consequence of war? Even the human society has evolved into the age of globalization and information. During the progress of economic integration between two sides of Taiwan Strait, the growing interactivity of economy does not have flow-out effect on the politics. Moreover the conflicts between two political powers become more and more apparent. Political conflicts also turn this area into the powder magazine of war in the world. The overall strength of China, the only imagined adversary of our country, has leapt forward since public revolution in 1978. For years, economic revolution has pushed the pace of China¡¦s military modernization faster and faster. For example, People¡¦s Republic Army has taken a great leap on the training exercise with the expansion of military exchange and with the equipment of new Soviet aircrafts. This new trend is taking away the advantage of quality of our Air Force. This brief takes the new trend in consideration and researches from the perspective of military operation. Questions are obtained from the basic fly training, the cornerstone of Air Force foundation. Taking the well-known strong force of US for example, this brief tries to realize the nature of Air Force through researching the ability of military personnel and to compare the difference of Air Force on basic fly training with other modern countries. The main objective of this brief tries to establish the basics of research and thesis using the research model concerning about subjects of constructing national defense. This brief uses the methods of analysis and comparison together to increase the precision of research theory as well. Even with the restrictions of flexibility and sampling, the first conclusion still shows there is no large difference on basic fly training between R.O.C and US. Cadets finished basic trainings have different fly abilities in R.O.C and US. The leading factors which conclude this difference are not only the training resources and environment but also the enforcement of training and the control of standards in US. Therefore, even the modernization of weapon gets faster and faster, the national force still has the great responsibility of defending national security. Bedsides expending more on military purchase, finding a way to strengthen the basic training which benefits the overall military power is not the one we can throw away.
