At first glance they appear to be World War II widows, however in the Soviet era back then women were integrated into the fighting units and played a significant role in combat, I'm not sure if that applied to the ladies of the Ukraine. These ladies may very well have earned those medals in combat. Regardless, congrats on the DD and Best wishes from Canada.
Some ladies here in Canada do it to honor their husbands who fought in the big wars. In Russia however women played a significant combat role and did their country proud. As with our soldiers, I do not forget them on our day of remembrance.
