The role of the rear in warfare, particularly in the context of Vietnam's 30-year resistance against the French and the Americans from 1945 to 1975, cannot be overstated. The rear area, which encompasses a vast range of activities, proved to be crucial in determining the success or failure of the conflict. During this period, the Vinh Linh Rear in Quang Tri, Vietnam, from 1965 to 1975, emerged as a paradigmatic example of how the rear operations could significantly impact the outcome of the war. It demonstrated remarkable achievements in various domains such as construction, economic development, culture, and societal organization. Moreover, Vinh Linh's rear area effectively deployed the people's war strategy, successfully resisting attacks from the air force, navy, and U.S. spy and commando operations. This not only ensured the safety of the populace but also provided support to the southern battlefield, particularly the Tri Thien theater. The Vinh Linh rear area's ability to combine economic development with military defense, social cohesion, and cultural resilience illustrates the multifaceted nature of rear operations in a protracted conflict. Its successes serve as a testament to the importance of comprehensive rear support in achieving strategic objectives in warfare. The article utilizes statistical research methods, along with incorporating several other methodologies such as classification method, retrospective method, periodic method, structural-systematic method, and comparative method. Delving deeply and comprehensively into the rear area, particularly Vinh Linh's rear area, during the resistance against the United States, is a significant and essential subject matter. Therefore, in the forthcoming period, it is imperative to have numerous research projects focusing on this content to extract valuable lessons and experiences in the endeavor to construct and safeguard the nation in the current context.
