Operation Coronado was a series of 11 operations conducted by the American Mobile Riverine Force in conjunction with various units of the Army of the Republic of Vietnam (South Vietnam) in the waterways of the Mekong Delta in the south of the country in an attempt to dismantle guerrilla forces and infrastructure of the Vietcong in the waterways of the Mekong, which had been a communist stronghold. The operations ran sequentially from June 1967 to July 1968. [1]
The series was named after Coronado Naval Base in California. There the American military had staged planning conference before adopting their riverine military strategy. [2]
In the Vietnam War, the Mobile Riverine Force (MRF) (after May 1967), 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 (of soldiers and equipment) and combat. The primary land base was at Đồng Tâm Base Camp, with a floating base which operated in the major rivers of the Mekong Delta. Soldiers and sailors went out in river boats from the floating base to assault the Viet Cong. During part of the 1968-69 period, there were two such mobile bases operating in different parts of the Delta, Mobile Riverine Groups Alpha and Bravo. The MRF played a key role in the Tet Offensive.
Operation Sealords was a military operation that took place during the Vietnam War.
The Patrol Craft Fast (PCF), also known as Swift Boat, were all-aluminum, 50-foot (15 m) long, shallow-draft vessels operated by the United States Navy, initially to patrol the coastal areas and later for work in the interior waterways as part of the brown-water navy to interdict Vietcong movement of arms and munitions, transport South Vietnamese forces and insert SEAL teams for counterinsurgency (COIN) operations during the Vietnam War.
A brown-water navy or riverine navy, in the broadest sense, is a 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 mechanized landing craft and tank landing ships, among other vessels.
The Patrol Air Cushion Vehicle (PACV), also known as the Air Cushion Vehicle (ACV) in Army and Coast Guard service, was a United States Navy and Army hovercraft used as a patrol boat in marshy and riverine areas during the Vietnam War between 1966 and 1970. Six hovercraft were built, three for the Army and three for the Navy.
The Republic of Vietnam Navy (RVNN; Vietnamese: Hải quân Việt Nam Cộng hòa - HQVNCH; was the naval branch of the South Vietnamese military, the official armed forces of the former Republic of Vietnam from 1955 to 1975. The early fleet consisted of boats from France; after 1955, and the transfer of the armed forces to Vietnamese control, the fleet was supplied from the United States. With American assistance, in 1972 the VNN became the largest Southeast Asian navy and, by some estimates, the fourth largest navy in the world, just behind the Soviet Union, the United States and the People's Republic of China, with 42,000 personnel, 672 amphibious ships and craft, 20 mine warfare vessels, 450 patrol craft, 56 service craft, and 242 junks. Other sources state that VNN was the ninth largest navy in the world. The Republic of Vietnam Navy was responsible for the protection of the country's national waters, islands, and interests of its maritime economy, as well as for the co-ordination of maritime police, customs service and the maritime border defence force.
The 47th Infantry Regiment is an infantry regiment of the United States Army. Constituted in 1917 at Camp Syracuse, New York, the regiment fought in World War I, and was later inactivated in 1921. Remaining nominally inactive throughout the interwar period but manned with Organized Reserve personnel, the 47th Infantry was reactivated in 1940 and subsequently fought during World War II in North Africa, Sicily, and Western Europe, then was inactivated in 1946. During the Cold War, the regiment saw multiple activations and inactivations, with service both in the Regular Army and the Army Reserve; it fought in Vietnam. Ultimately it was reactivated as a training regiment, and as of 1999, it has been assigned to Fort Moore and consists of two active battalions.
Operation Game Warden was a joint operation conducted by the United States Navy and South Vietnamese Navy in order to deny Viet Cong access to resources in the Mekong River Delta. Game Warden and its counterpart Operation Market Time are considered to be two of the most successful U.S. Naval actions during the Vietnam War.

Operation Coronado II was the second of eleven in the Operation Coronado series conducted by the U.S. Mobile Riverine Force (MRF) in conjunction with various units of the Army of the Republic of Vietnam (ARVN) in late July 1967 in an attempt to shut down Viet Cong (VC) strongholds in the Mekong Delta. Three battalions of American troops, along with two ARVN battalions, backed by helicopters and watercraft swept the area and waterways surrounding Mỹ Tho in search of VC forces. Two VC battalions were encountered and many captured, although both sides suffered numerous casualties. The Allied forces also cordoned off the area to search water traffic for VC supplies or suspects. The Americans credited the South Vietnamese 3rd Marine Battalion for the success of the operation.
Operation Coronado IV was the fourth of the Operation Coronado series of riverine military operations conducted by the U.S. Mobile Riverine Force (MRF), designed to shut down Viet Cong (VC) strongholds in the Mekong Delta.

The first part of the operation took place in Định Tường Province. After receiving intelligence that the VC 263rd Main Force battalion had been seen in the region, three Allied battalions were brought in on 12 September by helicopters and boats. Immediately there was heavy contact, and although the Allies reported killing 134, the majority of the VC escaped. Sweeps of the area resulted in another major confrontation with the VC on 15 September. During the four-day period, U.S. and ARVN reported 213 VC killed. The Allied forces then moved into adjoining Kiến Hòa Province. From 5–7 October another encounter with the VC 263rd Battalion resulted and the Allies reported 163 VC killed while losing seven.
Operation Coronado IX was a riverine military operation conducted by the Mobile Riverine Force (MRF) of the United States and elements of the Army of the Republic of Vietnam (ARVN) from November 1967 to January 1968 in an attempt to destroy Viet Cong (VC) strongholds in the Mekong Delta. In the middle of November, clashes resulted in the capture of VC supplies and hideouts. During this period, the VC lost 178 men but killed only 26. For the next few weeks there was little contact, although some abandoned VC bunkers were destroyed and supplies captured. On 4 December, a large engagement occurred when a VC battalion encountered the South Vietnamese 5th Marine Battalion. 266 VC were killed, mostly by the Marines. The Marines lost 40 killed, while the Americans suffered 9 dead. Over the next month and the Christmas period, there was only sporadic skirmishes, but at the start of the new year, there were some medium size battles in which the Americans killed a few dozen VC. After this there was little contact.
