How does someone earn an iron cross in prison?

Question

My fiance has 2 celtic iron cross tattoos, and all he will tell me is that he earned them. I cant get any other explaination, which is fine it just keeps nagging at me. It's knot work, but its continuous, it never stops. If that makes sense. Furthermore one is white, one is black. So just out of curiousity does anyone know how he might have earned them?

Answer 1

It stands for military skills, including bravery in face of the enemy and leadership. The iron cross (German) was a sign of bravery in WWII and was given to those after victory in war. Unfortunately it was then (mis)- used by the Nazis.
Some racist groups use it now to show that they are "aryans".

But then there are also the bikers who use the iron cross sign as a sign of independance.

Answer 2

By being a fine Aryan man.
