Nope not at all !!
Russian people may sometimes seem cold on the outside, because they're living a tough life and endure many hardships, but they're not cold at all. They're really emotional people with a huge heart and humongous soul. Also really sensitive individuals. Why do you think there have been so many great poets and writers that are Russian? Think Pushkin, Tolstoy, Dostoevsky, Gogol, and many many others. Russians have written novels about personal relationships and almost every sentence is filled with emotion. There is actually a term in literature that is called the "Russian Soul" describing Russian spirituality and becoming a possible national identity. So how is it that a COLD person could be so emotional?
I'm Russian myself and I know that Russians may seem to be mean sometimes, and not that smiley with people in general, but you should never take that on a personal level. Russians are warm at heart and once you befriend one you'll get a loyal friend for life. In company they're great hosts, outgoing, funny, caring :)
I don't know about the Spetsnaz per se, but you shouldn't stereotype a country for their deeds.
