Hi folks, new member here. Just come across this site and have been on for an hour and only scratched the surface. Cracking site. To my questions: 1--Did the SBS in 1940-41 help train the American UDT/naval commando style units, either here or in the US?. I know they did when UDT's arrived in the UK later in the war, but did any SBS/British naval experts go across the pond pre-Pearl Harbour to train the new US units?. 2--Are the US Seals heavily based on the SBS?. And did the SBS train the early SEALS?.
