Hey, I have a few questions about Judo. I want to know if its a Combative style that you could use in a real situation instead of just showing off and tournments. I want to know this because I was to be a Navy Seal and somone told me Judo was along the lines of what they teach Seals. I was also wondering what kind of styles of martial arts it has come from. And I would like to know a little bit about its history. Thank you for your time. Bye.
