Das Familienjuwel Achievement

As you are working towards Führerious Repetition (15G), aim for his groin area then take the shot. If you are on target, you will get the ‘testicle shot’ kill notification, a medal, and this achievement.

This might take a couple of attempts based on his position. If shooting with iron sights isn’t working for whichever type of weapon you’re using, try looking through your rifle scope and focusing. In my experience, he needed to be facing me for it to register as a testicle shot.
