The Army Corps 4 was formed in July 1974 during the resistance war against the US. Just five months after its establishment, the corps recorded their first victory in the Phuoc Long Road 14 battle for the liberation of Phuoc Long province (which is Phuoc Long town of Binh Phuoc province today).
In the spring of 1975, the corps joined with other armed units for the liberation of the South, leading to the reunification of the country and the end of the war. The unit also fought to safeguard the Southwest border of the country and completed its international mission.
President Tran Dai Quang lauded Army Corps 4 for its close coordination with the local Party Committee and government in building a community-based defence force.
As the major force of the Defence Ministry in the strategic southern area, the corps should focus on raising its leading capacity and combat strength, while cooperating with local authorities and other armed units to build defensive areas and draft plans to address complicated events to ensure the independence, sovereignty and territorial integrity of the country.
He asked the unit to pay attention to Party building and to develop a comprehensively strong unit, while studying and following President Ho Chi Minh’s moral example.
He requested that Army Corps 4 work closely with the local authorities to build a strong political system, while deepening relations with locals, assisting them in building new-style rural areas, and initiating social welfare activities.
The President also asked Army Corps 4 to organise for the Tet festival in a convenient and economical manner while ensuring continued combat readiness during the traditional event.
