It took a while but I finally did it. I got all 69 stars on special ops and the final achievement.

You can ask me for help if you're stuck on any missions.

I've been trying to complete special ops and get all 69 stars for an achievement but veteran is too hard alone. If you could help please send me a friend request or PM me. Thanks.

So far I've got 62 stars, these are the missions I need to complete:

Snatch & Grab
Wardriving
Terminal
Estate Takedown
Wetwork
High Explosive
Armor Peircing

EDIT: okay, I have 68 stars. I'm trying to do snatch and grab with a friend right now. It's really hard! :P
