Tip for those having trouble getting this achievement.
There's like 8 solutions already so read them to find where it's located...
BUT to those who the achievement will not pop for...
If it does not pop when you first hold X on the terminal, simple restart the mission from the start menu, walk past the set of stairs that leads to the "Records Terminal", hold X on the terminal that reads "Review Weapon System." Now turn around and go to the "Records Terminal" and try it.
This worked for me and I can only hope that it will work for everyone else.
If you add this to your guide please give credit.
I hope this helps.
