"Only by combining the various arms and services in a genuinely flexible way in various aspects, such as structural establishment, training, command, and management, will it be possible for our troops to constitute a powerful com- bat force. We should explore the new scientific system of combined army units, establish a corresponding command system, and formulate a set of rules and regulations for directing and managing the modernized combined army units. In building the army, we should satisfactorily integrate peacetime with war preparedness and the maintenance of the army with the use of military forces. While reducing the standing army, we should step up the building of the militia and reserve service and build up specialized technical soldiers and reserve officers in accordance with the new military service law promulgated some time ago. China has a large population and is rich in manpower resources. Provided that the people are well-trained, it does not make any difference if we have fewer troops in peacetime. As soon as a war breaks out, we can expand them immediately."
