How to unlock the Knows it All achievement in Supreme Commander 2 - Definitive Guide
This is quite simple really. Make sure that you press the back button to display your objectives and follow their various requirements in each mission. Majority of the secondary objectives are research items, so you should be able to get this achievement without much hassle, as long as you keep a list.
There's a very handy list on the Xbox360achievements.org website. (http://www.xbox360achievements.org/game/supreme-commander-2/...)

I don't like the posting of a link and the flat description.

Is there a way to see what I missed?

To see the Primary and Secondary objectives you must press on the current mission of the game.
Sometimes you will see Secondary objectives that are completely the opposite of a Hidden objective, so you will have to do the mission again to achieve the achievement:

If you press can see the objectives you have to complete. However in some missions you have a "time limit" or the missions are scripted. Save on a regular basis and you should be fine. For a list check the mission achievements.
