"Taking the modernization of our army as the key task is determined by the history and practical conditions of our army. This is an inexorable demand placed on our army by modern warfare. This is also the road our army should follow in order to advance to a higher stage. Generally speaking, the level of revolutionization of our army ranks first in the world. Armies of capitalist countries simply cannot attain such a high level of revolutionization. This is the absolute superiority of our army. The level of modernization and modern scientific knowledge of our army is not high and its weapons and equipment are comparatively backward. These are the weak links of our army. Modern warfare has manifested unprecedentedly new characteristics, and placed higher demands on the modernization of the army. If we fail to enhance the level of modernization of our army, it is difficult to adapt ourselves to modern warfare, and fulfill the sacred tasks of safeguarding the motherland the defending peace."
