If you are interested in Russian Spetsnaz training and can not afford complete DVD set, then get this one! These Russian Spetsnaz DVDs are cover almost all subjects and will give you a good amount of exercises and techniques. What I personally like about Russian Spetsnaz training is that everything is simple and clear. They are explaining everything very well. Compare to other Martial Arts, in Russian Spetsnaz, one technique can be applied for numerous applications: strikes, kicks, takedowns, release from grabs. So, you don't need to learn hundreds of different techniques. Just learn main Spetsnaz principles of self-defense and use them for every possible fighting situation. Well done DVDs! Russian Systema Spetsnaz training method is the best!
