Navy SEAL

The United States Navy Sea, Air, and Land (SEAL) Teams, commonly known as Navy SEALs, are the U.S. Navy's primary special operations force and a component of the Naval Special Warfare Command. Among the SEALs' main functions are conducting small-unit special operation missions in maritime, jungle, urban, arctic, mountainous, and desert environments. SEALs are typically ordered to capture or to kill high level targets, or to gather intelligence behind enemy lines.

All active SEALs are members of the U.S. Navy. The CIA's highly secretive and elite Special Operations Group (SOG) recruits operators from SEAL Teams, with joint operations going back to the MACV-SOG during the Vietnam War. This cooperation still exists today, as evidenced by military operations in Iraq and Afghanistan.

History

Origins

Although not formally founded until 1962, the modern-day U.S. Navy SEALs trace their roots to World War II. The United States Military recognized the need for the covert reconnaissance of landing beaches and coastal defenses. As a result, the joint Army, Marine Corps, and Navy Amphibious Scout and Raider School was established in 1942 at Fort Pierce, Florida. The Scouts and Raiders were formed in September of that year, just nine months after the attack on Pearl Harbor, from the Observer Group, a joint U.S. Army-Marine-Navy unit.

Scouts and Raiders

Recognizing the need for a beach reconnaissance force, a select group of Army and Navy personnel assembled at Amphibious Training Base (ATB) Little Creek, Virginia on 15 August 1942 to begin Amphibious Scouts and Raiders (Joint) training. The Scouts and Raiders' mission was to identify and reconnoiter the objective beach, maintain a position on the designated beach prior to a landing, and guide the assault waves to the landing beach. The unit was led by U.S. Army 1st Lieutenant Lloyd Peddicord as commanding officer, and Navy Ensign John Bell as executive officer. Navy chief petty officers and sailors came from the boat pool at ATB, Solomons, Maryland, and Army Raider personnel came from the 3rd and 9th Infantry Divisions. They trained at Little Creek until embarking for the North Africa campaign the following November. Operation Torch was launched in November 1942 off the Atlantic coast of French Morocco in North Africa.

The first group included Phil H. Bucklew, the "Father of Naval Special Warfare," after whom the Naval Special Warfare Center building is named. Commissioned in October 1942, this group saw combat in November 1942 during Operation Torch on the North African Coast. Scouts and Raiders also supported landings in Sicily, Salerno, Anzio, Normandy, and southern France.

The second group of Scouts and Raiders, code-named Special Service Unit No. 1, was established on 7 July 1943, as a joint and combined operations force. The first mission, in September 1943, was at Finschhafen in Papua New Guinea. Later operations were at Gasmata, Arawe, Cape Gloucester, and the east and south coasts of New Britain, all without any loss of personnel. Conflicts arose over operational matters, and all non-Navy personnel were reassigned. The unit, renamed 7th Amphibious Scouts, received a new mission, to go ashore with the assault boats, buoy channels, erect markers for the incoming craft, handle casualties, take offshore soundings, clear beach obstacles, and maintain voice communications linking the troops ashore, incoming boats and nearby ships. The 7th Amphibious Scouts conducted operations in the Pacific for the duration of the conflict, participating in more than 40 landings.

The third and final Scouts and Raiders organization operated in China. Scouts and Raiders were deployed to fight with the Sino-American Cooperative Organization (SACO). To help bolster the work of SACO, Admiral Ernest J. King ordered that 120 officers and 900 men be trained for "Amphibious Raider" at the Scout and Raider school at Fort Pierce, Florida. They formed the core of what was envisioned as a "guerrilla amphibious organization of Americans and Chinese operating from coastal waters, lakes, and rivers employing small steamboats and sampans." While most Amphibious Raider forces remained at Camp Knox in Calcutta, three of the groups saw active service. They conducted a survey of the upper Yangtze River in the spring of 1945 and, disguised as coolies, conducted a detailed three-month survey of the Chinese coast from Shanghai to Kitchioh Wan, near Hong Kong.

Naval Combat Demolition Units (NCDUs)

In September 1942, 17 Navy salvage personnel arrived at ATB Little Creek, Virginia for a week-long course in demolitions, explosive cable cutting, and commando raiding techniques. On 10 November 1942, the first combat demolition unit successfully cut cable and net barriers across the Wadi Sebou River during Operation Torch in North Africa. This enabled to traverse the water and insert U.S. Rangers who captured the Port Lyautey airdrome.

In early May 1943, a two-phase "Naval Demolition Project" was directed by the Chief of Naval Operations "to meet a present and urgent requirement". The first phase began at ATB Solomons, Maryland with the establishment of Operational Naval Demolition Unit No. 1. Six officers and eighteen enlisted men reported from the Seabee's NTC Camp Peary dynamiting and demolition school, for a four-week course. Those Seabees, led by Lieutenant Fred Wise CEC, were immediately sent to participate in the invasion of Sicily. At that time Lieutenant Commander Draper L. Kauffman, "The Father of Naval Combat Demolition," was selected to set up a school for Naval Demolitions and direct the entire Project. The first six classes graduated from "Area E" at NTC Camp Peary. LCDR Kauffman's needs quickly out-grew "Area E" and on 6 June 1943, he established NCDU training at Fort Pierce. Most of Kauffman's volunteers came from the navy's Civil Engineer Corps (CEC) and enlisted Seabees. Training commenced with a grueling week designed to filter out under-performing candidates. Eventually given the name "Hell Week" by NCDU recruits, this rigorous course was integrated into UDT training and remains a part of modern day Navy Seal training today.

By April 1944, a total of 34 NCDUs were deployed to England in preparation for Operation Overlord, the amphibious landing at Normandy. On 6 June 1944, under heavy fire, the NCDUs at Omaha Beach managed to blow eight complete gaps and two partial gaps in the German defenses. The NCDUs suffered 31 killed and 60 wounded, a casualty rate of 52%. Meanwhile, the NCDUs at Utah Beach met less intense enemy fire. They cleared of beach in two hours, another by the afternoon. Casualties at Utah Beach were significantly lighter with six killed and eleven wounded. During Operation Overlord, not a single demolitioneer was lost to improper handling of explosives. In August 1944, four NCDUs from Utah Beach plus nine others participated in the landings Operation Dragoon in southern France. It was the last amphibious operation in the European Theater of Operations. Once the European invasions were complete, Real Admiral Kelly Turner requisitioned all available NCDUs from Fort Pierce for integration into the Underwater Demolition Teams (UDTs) operating in the Pacific Theater.

Thirty NCDUsThe Water Is Never Cold, James Douglas O'Dell, 2000, Brassey's, 22841 Quicksilver Drive, Dulles, Va. 20166, had been sent to the Pacific prior to Normandy. NCDUs 1–10 were staged on Florida Island in the Solomon Islands (archipelago) during January 1944.World War II US Navy Special Warfare Units, Eugene Lipak, Osprey Publishing, POB 3985, NY, NY, 10185. 2014, p. 25 NCDU 1 went briefly to the Aleutians in 1943. NCDUs 4 and 5 were the first to see combat by helping the 4th Marines at Green Island and Emirau Island. A few were temporarily attached to UDTs. Later NCDUs 1–10 were combined to form Underwater Demolition Team Able. Six NCDUs: 2,3, 19, 20, 21 and 24 served with the Seventh Amphibious Force and were the only remaining NCDUs at the end of the war. The Naval Special Warfare Command building is named for LTJG Frank Kaine CEC commander of NCDU 2.

OSS Maritime Unit

Much like their brethren in the US Army Special Forces (aka Green Berets), the Navy SEALs claim a lineage to the Office of Strategic Services (OSS). The OSS was a paramilitary organization and also a progenitor of the CIA. Army Special Forces, founded in 1952 by former members of the OSS, established the first military special operations combat diver units nearly a decade before the SEALs were created in 1962. Some of the earliest World War II predecessors of the Green Berets and SEALs were the Operational Swimmers of OSS.

The OSS executed special operations, dropping operatives behind enemy lines to engage in organized guerrilla warfare as well as to gather information on such things as enemy resources and troop movements. British Combined Operations veteran LCDR Wooley, of the Royal Navy, was placed in charge of the OSS Maritime Unit (MU) in June 1943. Their training started in November 1943 at Camp Pendleton, California, moved to Santa Catalina Island, California in January 1944, and finally moved to the warmer waters of The Bahamas in March 1944. Within the U.S. military, they pioneered flexible swimfins and diving masks, closed-circuit diving equipment (under the direction of Dr. Christian J. Lambertsen), the use of Swimmer Delivery Vehicles (a type of submersible), and combat swimming and limpet mine attacks.

The OSS MU mission was "to infiltrate agents and supply resistance groups by sea, conduct maritime sabotage, and develop specialized maritime surface and subsurface equipment and devices." The MU operated in several theaters. In the Mediterranean, a fleet of hired Greek wooden fishing vessels—called caiques—covertly supported OSS agents in Albania, Greece, and Yugoslavia. After Italy surrendered, the MU and Mariassalto, an elite Italian special operations naval unit, operated against the Germans. In the Far East, the MU operated in conjunction with an Operational Group to attack Japanese forces on the Arakan coast of Burma. They jointly conducted reconnaissance missions on the Japanese-held coast, sometimes penetrating several miles up enemy-controlled rivers.

The MU developed or used several innovative devices that would later allow for the creation of a special operations combat-diver capability, first in Army Special Forces (Green Berets) and later in US Navy SEAL units. Perhaps the most important invention in the realm of special operations diving was the Lambertsen Amphibious Respiratory Unit (LARU) invented by Dr. Christian J. Lambertsen. The Lambertsen unit permitted a swimmer to remain underwater for several hours and to approach targets undetected because the LARU did not emit telltale air bubbles. The LARU was later refined, adapted, and the technology used by the U.S. Army, U.S. Navy, and NASA. The Army Special Forces Underwater Operations School at Key West, Florida, the home of Special Forces maritime operations, draws its roots from the Maritime Unit.

Lambertsen began his involvement with OSS as a medical student offering the use of his technology to the secretive organization in 1942. In 1944 he was commissioned as an Army Officer and later joined the OSS as an Operational Swimmer. Lambertsen himself led the OSS Maritime Unit on covert underwater missions to attach explosives to Japanese ships. Dr. Christian Lambertsen is remembered today as the 'Father of Military Underwater Operations'. Along with all the members of the OSS Maritime Unit, he was made honorary Green Berets and recognized by organizations like the UDT Navy Seal Association for their heroic and critical work.

In May 1944, Colonel "Wild Bill" Donovan, the head of the OSS, divided the Maritime Unit into four groups and approached General MacArthur and Admiral Nimitz about using OSS men in the Pacific Gen. MacArthur had no interest at all. Adm Nimitz looked at Donovan's list of units and also said no thank you except he could use the swimmers from the Maritime Unit to expand the UDTs. He was primarily interested in them for being swimmers, not their military training. The interest in the tactical applications of the OSS Operational Swimmers' training only developed later but most of Group A's gear was put into storage as it was not applicable to UDT work. The OSS was very restricted in operations in the Pacific. ADM Nimitz approved the transfer the five officers and 24 enlisted men of Maritime Unit Operational Swimmer Group A led by Lieutenant Choate. They became part of UDT 10 in July 1944. LT Choate would become commander of UDT 10. The rest of MU Group A would fill most of UDT 10's command offices as well as many of the swimmers. Five of the OSS-trained men participated in the very first UDT submarine operation with in the Caroline Islands during August 1944. Three of the men failed to make the rendezvous point for extraction. They were reported captured in Japanese communications and identified as "BAKUHATAI" — explosive ordnance men. They were never seen again and are listed as MIAs.

Underwater Demolition Teams (UDTs)

The first units designated as Underwater Demolition Teams were formed in the Pacific Theater. Rear Admiral Kelly Turner, the Navy's top amphibious expert, ordered the formation of Underwater Demolition Teams in response to the failed invasion at Tarawa
