... This is Kazachya Bay Brigade company of Marines (Naval Infantry) of the Black Sea Fleet Naval Infantry Brigade marching in Greece about 10 years ago, including anthem of Sevastopol (in the end) called Legendary Sevastopol.
P.S. And if I will tell you what was across Kazachya Bay--you wouldn't believe me, but I was there and those people were our good friends. I'll give you a hint--search a great Hollywood movie The Day of the Dolphin (with George C. Scott), wink, wink.
