Panzergrenadierbattalion 13 of the Bundeswehr (1980-1992, dissolved because cold war over). You’ll find it in more insignia not to mention coat of arms of towns but that one is closest to Azov in the sense that it’s simply a singular Wolfsangel. At least among the ones I could find within 10 seconds of googling.
The Wolfsangel is not a Nazi symbol as such. If you want to outlaw everything the Nazis ever used then nothing would be left, including the Antifa flags because they totally did try to appropriate those. They’re getting off on that shit and you seem to be willing to play right into their hands.
