This article studies the military art of Vietnam from the times of the monarchy to modern history. While previous studies on Vietnamese military art have examined the policy of “Ngu binh u nong”1, this study further clarifies Vietnam's military policy throughout the nation's history. This work suggests that the ancestors' policy of “Ngu binh u nong” was inherited and developed by the Communist Party of Vietnam not only as military organization, but as a strategy of economic development that combines with national defence, a national governance policy, as well as a national defence strategy for Vietnam.
