WWII Soviet Naval Infantry Brigade, 3 battalions strong with AT, artillery, SMG, Pioneer, and Mortar battalions attached. 15mm Battle Honors figures based for Command Decision Test of Battle (one stand = one platoon/battery). The Naval Infantryman wore the distinctive black trousers/ dark blue tunic/black peacoat. Their dark attire and zeal (some unit cohesion and often fighting on their 'home turf' naval base) when committed earned them the sobriquet "black death" from the German Army.
