Since the government moved to Taiwan in 1949, the development of Taiwan's politics has undergone from an authoritarian regime to democratic transformation which has led to the consolidation and deepening of democracy. During the political development process, Taiwan military's interaction with the society has also changed from the authoritarian domination to the military nationalization. Under the value of a pluralistic democratic society, the value culture of the military also tends to develop in multiple ways. Confronted with such a huge change, the armed forces are bound to re-adjust its own position and role. The most important thing in the process of military nationalization is the establishment of a political neutral system for the military, which will enable the military to become a strong backing for stable social development as the country moves toward the development of democracy. The purpose of this paper is to study the norms of the political neutrality of Taiwan military. By introducing the norms of the political neutrality in the United States military, we can examine what we lack and what we can take for improvements. Finally, it is found that there are three impacts on the political neutrality of military forces in Taiwan: the lack of clarity of the legal system, the overemphasis on restrictive regulations, and the lack of awareness of the rights and legal norms of military forces. It also proposes the following three suggestions: First, to promote the legislation of political neutrality in military as soon as possible; second, referring to the norms of the US military and ensuring the political participation of military force in the spirit of the Constitution; third, high-ranking retired generals should be included in the political neutrality of military forces.
