Great Russian Spetsnaz 2 DVD set: theory + practice! The first DVD is about Systema Spetsnaz combat style, the difference between Russian Spetsnaz and other martial arts, plus fundamental principles of Russian hand to hand combat. The second DVD is a great combination of vital fighting techniques: safe falls, training with weapons, combat with multiple opponents, impressive striking techniques, grabs, chokes and holds releases and amazing footage of self-defense against a dog attack! And of course, I absolutely love the atmosphere of the training… the sense of humor brings a lot of fun to the learning process!
