Cossacks are the Warrior people of the Russians. I met a cossack who was a coke dealer, he spoke perfectly Bosnian language (he served probably in Balkan War), he did not identify him as Russian.
Are they Slavs? Or a mix of Slavs and Tartars? Why they are smaller then average Russian. We South-Slavs are far taller then Russians.
What is the provenience of this people, who learn with the age of 7 to shoot?
One of my ancestors got wounded in the Ottoman-Russian Krim war... we Sandzaks have the tradition when a son is born to buy a gun and as soon as the son can hold the weapon he gets it as present. We have the saying:" Our homes, our barraks."
