@Unease P34nut - I believe I am, I will check again and get back to you.
I still can't figure out the "extra credit" achievement issue I'm having. I have triple checked every assault op and they are all complete yet the achievement will not unlock. The only thing I've found is that on the assault ops for Operation A: Mission 1; It says to kill 20 Elites and it shows that I've killed 80 out of 20.
