Why didn't you just pull the achievement tiles from your profile on Xbox.com? They're all blank and it looks like shit, sorry to say.
Pretty sure I got 'Never Saw it Coming' when I jumped off a shipping container (located in some of the outposts). You must also have the skill, otherwise you will be falling to your death, or maybe a little scratch.
Oh as well, you can miss an achievement. How do you liberate an outpost without triggering the alarm if you have captured all of the outposts?
