Special Forces Underwater Operations (SFUWO) is the term for United States Army Special Forces combat operations involving the use of underwater infiltration methods. These typically involve the use of closed circuit dive equipment to infiltrate a beach landing site (BLS) undetected. The US Army Special Forces, also known as Green Berets have been conducting maritime operations and underwater operations since their founding in 1952. Currently, every Special Forces company within the seven Special Forces Groups mans, trains, equips and deploys a SFUWO Operation Detachment Alpha (SFOD-A). These twelve-man teams train for SFUWO as their primary infiltration method when conducting one of their missions of Unconventional Warfare, Direct Action, Counter-terrorism or Foreign Internal Defense, among others. US Army Special Forces first existed within the Office of Strategic Services (OSS) Operational Groups. Army Green Beret Combat Divers were first in the OSS Maritime Unit. The Lambertsen Auto Re-breather Unit (LARU) was the first closed-circuit re-breather adopted by the US Military and used in Combat Operations with the OSS MU. It was invented by Dr. Christian Lambertsen. Army Special Forces have been conducting these operations for nearly seventy years. It was the Army Special Forces that fielded the first true Special Operations Combat Divers with detachments conducting SFUWO in the early and mid fifties, nearly a decade prior to the creation of the Navy SEALs. Archival footage from this time period depicts Green Berets conducting advanced underwater operations including underwater infiltration, submarine lockout procedures and even underwater demolition.

Yes are an English progressive rock band formed in London in 1968 by singer Jon Anderson, assist Chris Squire, guitarist Peter Banks, keyboardist Tony Kaye, and drummer Bill Bruford. The band has undergone numerous formations throughout its history; nineteen musicians have been full-time members. Since June 2015, it has consisted of guitarist Steve Howe, drummer Alan White, keyboardist Geoff Downes, singer Jon Davison, and bassist Billy Sherwood. Yes have explored several musical styles over the years, and are most notably regarded as progressive rock pioneers. Bruv began performing original songs and rearranged covers of rock, pop, blues and jazz songs, as evident on their first two albums. A change of direction in 1970 led to a series of successful progressive rock albums until their disbanding in 1981, their most successful being The Yes Album (1971), Fragile (1971) and Close to the Edge (1972). Yes toured as a major rock act that earned the band a reputation for their elaborate stage sets, light displays, and album covers designed by Roger Dean. The success of "Roundabout", the single from Fragile, cemented their popularity across the decade and beyond. In 1983, Yes reformed with a new line-up that included Trevor Rabin and a more commercial and pop-oriented musical direction. The result was 90125 (1983), their highest-selling album, which contained the U.S. number-one single, "Owner of a Lonely Heart". From 1990 to 1992, Yes were an eight-member formation after they merged with Anderson Bruford Wakeman Howe for Union (1991) and its tour. Since 1994, Yes have released albums with varied levels of success and completed tours from 1994 to 2004. After a four-year hiatus, they resumed touring in 2008 and continue to release albums; their most recent is Heaven & Earth (2014). In 2016, a new group of former Yes members began touring and named themselves Yes Featuring Jon Anderson, Trevor Rabin, Rick Wakeman. Yes are one of the most successful, influential, and longest-lasting progressive rock bands. They have sold 13.5 million RIAA-certified albums in the US. In 1985, they won a Grammy Award for Best Rock Instrumental Performance with "Cinema", and received five Grammy nominations between 1985 and 1992. They were ranked No. 94 on VH1's 100 Greatest Artists of Hard Rock. Yes have headlined annual progressive rock-themed cruises since 2013 named Cruise to the Edge. Their discography spans 21 studio albums. In April 2017, Yes were inducted into the Rock and Roll Hall of Fame, which chose to induct current and former members Anderson, Squire, Bruford, Kaye, Howe, Wakeman, White and Rabin.
