Hi, I'm a 19 year old guy, I'm hoping to join the army in the near future (Soilder rank) but I'm by no means taking it lightly. I understand the SAS is the best special forces regiment and the most exclusive special forces unit on the entire planet, and to get there I'd have to toil, really prove myself. I still want to get there. I'm not resting my entire armed forces career on it, but I'd really like to and relish the opportunity if it came up. In general, is it considered a childish ambition to want to join the SAS?
