They a Dark Angels successor chapter?
It might be true. No chapter specified but DA symbolism is strong amongs them.
Can you tell me, which chapter they belongs to? I can't identify the symbol properly.
When I was initially painting those models I've never thought that they will become a single army cause I wasn't a WH40K gamer. I just found painting scheme I liked. No chapter specified. You can think of them as a DA successor chapter if you like.
Nice Background! and good work with the marines
