This article is about the weapons used in the Vietnam War, which involved the People's Army of Vietnam (PAVN) or North Vietnamese Army (NVA), National Liberation Front for South Vietnam (NLF) or Viet Cong (VC), and the armed forces of the China (PLA), Army of the Republic of Vietnam (ARVN), United States, Republic of Korea, Philippines, Thailand, and the Australian, New Zealand defence forces, and a variety of irregular troops.
In the Vietnam War, the Mobile Riverine Force (MRF), initially designated Mekong Delta Mobile Afloat Force, and later the Riverines, were a joint US Army and US Navy force that comprised a substantial part of the brown-water navy. It was modeled after lessons learned by the French experience in the First Indochina War of Dinassaut and had the task of both transport and combat. The primary base was at Đồng Tâm Base Camp, with a floating base at the base of the Mekong River. It played a key role in the Tet Offensive.

The term brown-water navy or riverine navy refers in its broadest sense to any naval force capable of military operations in littoral zone waters. The term originated in the United States Navy during the American Civil War, when it referred to Union forces patrolling the muddy Mississippi River, and has since been used to describe the small gunboats and patrol boats commonly used in rivers, along with the larger "mother ships" that supported them. These mother ships include converted World War II-era Landing Crafts and Tank Landing Ships, among other vessels.

The Yugoslav monitor Sava is a Temes-class river monitor that was built for the Austro-Hungarian Navy as SMS Bodrog. She fired the first shots of World War I just after 01:00 on 29 July 1914, when she and two other monitors shelled Serbian defences near Belgrade. She was part of the Danube Flotilla, and fought the Serbian and Romanian armies from Belgrade to the mouth of the Danube. In the closing stages of the war, she was the last monitor to withdraw towards Budapest, but was captured by the Serbs when she grounded on a sandbank downstream from Belgrade. After the war, she was transferred to the newly created Kingdom of Serbs, Croats and Slovenes, and renamed Sava. She remained in service throughout the interwar period, although budget restrictions meant she was not always in full commission.

NMS Mihail Kogălniceanu was a monitor of the Romanian Navy. She saw service in both world wars, being the most successful vessel in her class of four ships. Like her three sisters, she was initially built as a river monitor, but in early 1918, she was converted to a sea-going monitor. During the Second Balkan war, she supported the Romanian crossing of the Danube into Bulgaria. During World War I, she carried out numerous bombardments against the Central Powers forces advancing along the shore of the Danube and carried out the last action of the Romanian Navy before the 11 November 1918 armistice. She later fought successfully against Bolshevik naval forces during the early months of the Russian Civil War, helping secure the Budjak region. During the interwar period, she contributed to the suppression of the Tatarbunary Uprising and was rearmed with longer main guns towards the end of the 1930s. During World War II, she fought several engagements against the Soviet Navy in the first month of the Eastern Front, but was ultimately sunk by Soviet aircraft shortly after Romania ceased hostilities against the Soviet Union, on 24 August 1944.
