Since Russia began its invasion of Ukraine last year, the Ukrainian government and NATO allies have posted, then quietly deleted, three seemingly innocuous photographs from their social media feeds: a soldier standing in a group, another resting in a trench and an emergency worker posing in front of a truck.

In each photograph, Ukrainians in uniform wore patches featuring symbols that were made notorious by Nazi Germany and have since become part of the iconography of far-right hate groups.

The iconography of these groups, including a skull-and-crossbones patch worn by concentration camp guards and a symbol known as the Black Sun, now appears with some regularity on the uniforms of soldiers fighting on the front line, including soldiers who say the imagery symbolizes Ukrainian sovereignty and pride, not Nazism.
