Mma questions, please answer?

hello, i am going to be taking up mma, and i have a few questions, i want to be like the russian spetsnaz, because they are awesome! so I will hopefully be taking up sambo as a ground fighting style, but i also want to do bjj, and of course judo to develop roots in ground fighting, so i hope this is good for the ground, and for striking, i am un sure what i want to do, i love muay tai, but i am not good on the of my feet, and i do not like tae kwon do or kenpo/kempo karate, so what would be a good striking ma? and also, is systema real? is it really used by spetsnaz, please answer all my questions
