HELSINKI (AP) — Finland’s Air Force Command has discreetly dropped its swastika logo as unit emblem — after a century — and replaced it with a neutral insignia featuring a golden eagle.

The change — to avoid false and uncomfortable associations with Nazi Germany’s notorious logo — took place in January 2017 but wasn’t announced publicly by the military of the Nordic nation at the time. Teivo Teivainen, professor of world politics at the University of Helsinki, currently doing research on the use of swastikas in Finland in the 1920s and 1930s, noted the issue in a Twitter post this week that brought it to public attention.
