1st Corps (Vietnam People's Army)

1st Corps (Vietnam People's Army) is a primary strategic mobile combined arms formation of the Vietnam People's Army, first established during the Vietnam War. Known as the "Determined to Win Corps," it played a decisive role in the final Ho Chi Minh Campaign that led to the Fall of Saigon in 1975. Following the war, the corps was heavily engaged in the Cambodian–Vietnamese War and the Sino-Vietnamese War, solidifying its reputation as an elite force. Today, it remains a key component of Vietnam's national defense strategy, headquartered in Tam Điệp, Ninh Bình Province.

History

The corps was officially formed on 24 October 1973 in Thái Nguyên Province, under the command of General Lê Trọng Tấn, as part of the North Vietnamese military's shift towards large-scale conventional warfare. Its creation was a direct response to the strategic demands of the final phase of the Vietnam War, intended to function as a powerful, mobile strike force. During the Spring 1975 offensive, the 1st Corps was a central component of the People's Army of Vietnam's main thrust, participating in critical battles like the Battle of Xuân Lộc before spearheading the final assault on Saigon. In the post-war period, it was rapidly deployed to the southwest border, participating in the overthrow of the Khmer Rouge regime in Phnom Penh during the Cambodian–Vietnamese War, and subsequently defended the northern border during the 1979 Sino-Vietnamese War.

Organization

As a combined arms corps, it integrates multiple division-level formations and specialized branches under a unified command structure. Its core combat power traditionally resides in several infantry divisions, such as the 308th Division, 312th Division, and 320th Division, which are among the most celebrated units in the Vietnam People's Army. The corps is further supported by organic artillery, air defense, tank and armored units, engineer brigades, and signal regiments, enabling it to conduct independent, large-scale operations. This structure has been modernized over time, with its headquarters currently situated in Tam Điệp, placing it strategically within the Red River Delta region.

Commanders

Leadership of the corps has been held by several distinguished Vietnamese military officers. Its first commander was General Lê Trọng Tấn, a highly respected figure who later became Chief of the General Staff. He was succeeded by other prominent generals including Lê Ngọc Hiền and Nguyễn Huy Hiệu, both of whom led the corps during the intense fighting of the Cambodian–Vietnamese War and the Sino-Vietnamese War. These commanders were instrumental in translating the strategic directives of the Ministry of National Defence (Vietnam) and the General Staff of the Vietnam People's Army into successful battlefield operations, cementing the corps' legendary status.

Engagements and campaigns

The corps' operational history is defined by its participation in the most significant conflicts of modern Vietnam. Its inaugural and most famous campaign was the Ho Chi Minh Campaign, where it broke through formidable Army of the Republic of Vietnam defenses. In 1978-1979, it formed part of the main invasion force during the Cambodian–Vietnamese War, engaging in operations across Cambodia from Svay Rieng to Phnom Penh. Immediately following, it was redeployed to confront the People's Liberation Army along the northern frontier, fighting in major engagements during the Sino-Vietnamese War, particularly in the Lạng Sơn sector. These consecutive campaigns demonstrated its strategic mobility and high combat readiness.

Legacy and honors

The 1st Corps is regarded as one of the most decorated and elite formations in Vietnamese military history, embodying the offensive spirit of the Vietnam People's Army. For its extraordinary service, the corps has been awarded the title of Hero of the People's Armed Forces twice, along with numerous other state and military honors. Its legacy is celebrated annually on its founding anniversary, and its history is a central part of the narrative at museums like the Vietnam Military History Museum in Hanoi. The "Determined to Win" ethos continues to be a touchstone for military training and patriotism within Vietnam.
