The purpose of studying military theory course is to change our knowledge structure, improve our comprehensive quality and strengthen our national defense concept. With the change of knowledge structure, through the study of China's modern national defense history, it is realized that China is backward because of the backward social system, China was slaughtered in modern territory, people were slaughtered, wealth was plundered and national dignity was trampled on wantonly. After countless explorations, setbacks and failures, the people of China have finally found socialism, the correct road that conforms to the objective laws of human social development, and thus embarked on the road of independence and prosperity. Through the study of these, we know that the system suitable for the country and society can make our motherland prosperous, and these historical studies are also a kind of patriotic education. Patriotism is not only the profound feelings for the motherland and the heroic spirit of defending the motherland, but also the spirit of caring for the destiny and future of the motherland and striving for its future, prosperity and progress. Only when China is strong, no country dares to invade us. Only socialism can make China prosperous. So our love for our country and our love for socialism are completely consistent. In today's China, loving the motherland means loving socialism, which is determined by the objective laws of historical development and the inevitable choice of the people of China. In my opinion, the changes in the knowledge structure caused by the study of military theory courses are reflected in establishing a correct world outlook, strengthening socialist beliefs, and sublimating the strong thought of loving the motherland into profound and rational patriotic thoughts. The improvement of comprehensive quality is reflected in ideological and moral quality. After 90, most of us are only children at home. We grew up under the care of our parents. We have never suffered or been tired, so we seldom have the chance to live this kind of collective life. So pay attention to your own interests everywhere. Through the study of military theory courses, we have established correct values, that is, collective values. The people's army is the embodiment of collectivism, which is the idea that people's interests are the highest interests and personal interests are subordinate to people's interests. Therefore, without collectivism, there would be no people's army and there would be no victory in China's revolutionary war. The purpose of the people's army is to serve the people. No matter in the era of revolutionary war, or in the era of peaceful construction, no matter in the battlefield with heavy gunfire, or in the time of emergency rescue and disaster relief, when the people need it most, the people's army will always be at the forefront and devote itself to the interests of the people. The spirit of collectivism embodied by the people's army has become a powerful driving force for the construction of socialist spiritual civilization today. In today's society, the state promotes the development of productive forces through the socialist market economy, recognizes reasonable personal interests, mobilizes people's enthusiasm for developing productive forces, and improves people's living standards. However, we must still uphold and advocate the leading position of collectivism values in our society in order to safeguard the socialist nature of our society. Therefore, all of us should adhere to the values of collectivism, consciously safeguard the overall interests of the country and the people, dare to sacrifice personal interests, have a strong sense of social responsibility for the country and the people, truly improve our moral quality, and make ourselves builders and successors of the socialist cause, so as to ensure that our motherland can always adhere to the direction of socialist development in the future. With regard to national defense consciousness, it is undeniable that the contest between countries in 2 1 century is based on comprehensive national strength and oriented by economic strength. However, we should also see that when the competition between countries is fierce, extreme forms of contest will appear. This extreme form of competition is war. In today's China, there are many security risks. Nansha Islands are occupied by small countries in Southeast Asia, and the issue of Taiwan Province Province has not been resolved. The East China Sea issue between China and Japan and the Diaoyu Islands dispute are escalating. At present, China's national defense form is not optimistic, and the crowing on the surface actually hides rough waves. Great power diplomacy is a contest between countries based on strength. Without strength, there is no diplomatic status. In the history of the world, no country has ever achieved such a high international status without strength. International status is not innate, and we must strive for it by our own efforts. Of course, China is not unaware of this now. China invests a lot of money to support national defense construction every year. However, this is not enough. National defense is not only a matter for the country and the army, but also a matter for everyone in China. It can be said that everyone in China is an integral part of the national defense force. In the patriotic education of military theory, the concept and consciousness of national defense have been strengthened. At the same time, it also enables us to establish a correct outlook on life. We learn from the history of China's revolutionary war and the proletarian revolutionary heroism of the people's army, and establish a correct outlook on life while enhancing the national defense consciousness of bravely defending the motherland. We don't want war, but if the enemy insists on imposing it on us, for the sake of the sovereignty of the motherland, the dignity of the nation and the interests of the people, we should dare to face the war with dauntless spirit.
