Sports anyone?? (Hannover)

Hello everyone, I´m interested in starting a military inspired sports group. If anyone is interested we should try and get together for next weekend. I worked in the special operations community of the US military for a number of years and would love to do some combat sports related activities, if anyone is interested in getting in shape. We could also focus on self defense and tacticial exercises as well. Anyways please let me know..otherwise I guess I´ll just have to have some fun by myself!!!
