In early 1978, the British Special Air Service sent an advisory team to Hong Kong, which was initially to evaluate the SDU and subsequently trained two land assault teams resulting in considerable changes to SDU equipment and tactics. In 1982, the British Special Boat Service sent an advisory team to Hong Kong to establish a water assault team including training in military diving. The water assault team was later disbanded in 2000, with the assaults teams now integrated as new training standards required all officers to be equally trained and proficient in maritime operations.
