I am American, and recently began dating a man who was in the British military. He told me that he is an ex SAS. I was not familiar with the SAS, so googled it and learned that a lot of people seem to claim to have been in the SAS when actually they were not. He now is an American citizen and works for an anti terrorist company. Seems pretty legit to me... but I also read that if they were truly ex SAS then they never speak of it.. even when out of the service. Thoughts?
