As the description is so vague and I tried lots of different things to unlock this to no success I thought I would post how to get it to save people wasting hours like I did on this achievement.

1) First of all it unlocks before you assault the illusive mans base (the cut scene before you arrive) so make sure you have a save before that point. You can beat the game already then come back to this achievement, just so long as you make a save before you assault his base.

2) You will have to play multiplayer to unlock this achievement (which I wish I realized sooner and would have saved myself a lot of time). As I did everything possible in single player, every side mission and main mission, scanned and explored every planet and didn't have enough points.

3) The way it works is you have your war assets (you get from doing side quests and scanning planets). Now whatever theatre of war % you have increases your war assets you gained in single player by so much. 50% is the standard amount you will be at if you've never played MP. To increase this % you have to play and succeed at multiplayer.

4) To view your points you need to go the war room and just take note of the bottom number 'Effective Military Strengh' as this is the number what matters.
As for the points total itself I'm not sure the exact amount you need but I had 4122 so I would assume for being safe lets say you need 4.000. I had 3300ish from single player, then I played multiplayer to just 50> 63% across all zones which boosted me to 4122. So just the 13% increase gave me near 1k in extra war asset points to put me in the achievement criteria.
