You’ll often see it where you see support for Russian President Vladimir Putin’s war: “Z” is emblazoned on billboards in major Russian cities, and on some Russia supporters’ cars, where it doubles as a target for supporters of Ukrainian democracy.

The letter Z has been seen recently on Russian tanks, the shirt of a Russian gymnast, on cars and t-shirts and even pictured in the snow.
