Man there are a lot worse organizations to get beat up by than the SAS.
When we were dismissed at the end of training, we swarmed the DI. There were 20 of us and one of him. We were almost outnumbered.
I remembered some of what he tried to teach us when we got a mission. It kept me alive in a pretty dicey situation. Hungarian border guard wanted us to accompany him and we didn't want to.
