The Naval Infantry Brigades (sometimes NI; Vietnamese: Lữ đoàn Hải quân Đánh bộ) are a component and virtually a combat arm under the Vietnam People's Navy that have the task of stationing troops to protect islands, rocks and inland naval bases, or attacking or landing by sea on the mainland or on the islands occupied by foreign countries, protecting Vietnam's territorial sovereignty and territorial sea.

[3] The modern day Vietnamese Naval Infantry has its origin during the Vietnam War when in 1969, based on the success of their sapper unit they created two years before, the People's Army of Vietnam decided to raise a 500-man sapper unit with amphibious capabilities.

In the evening of January 6, a group of commandos of 87 people secretly landed and attacked to occupy a Khmer Rouge artillery position protecting the coast, at the same time, 130 mm artillery began to bombard Khmer Rouge positions.

Each trip is the most elite members when they have been trained together with the forces and passed the final medical examination.

[7] Two Brigades 101 and 147 today are the core force performing the task of defending the islands in the vast waters of the Vietnamese homeland.
