This achievement is pretty straight forward. You simply have to win 10 Storm or Destruction matches in online matchmaking. The wins from each game type are combined to meet the requirements for this achievement. Meaning, for example, you could win five matches of Storm and five matches of Destruction, or some other combination of the two.

If you and your teammates do not play the objective, you will not unlock this achievement.How to play Storm: When attacking, your goal is to sit at the enemy's command post (marked by a yellow icon on your mini-map) to capture three command posts in 15 minutes. To capture command posts, simply sit in the vicinity of the the icon. The more teammates you have on the command post, the faster it will capture. After 15 minutes or all three captures, teams will switch sides and objectives.
When defending, your goal is to stop the enemy from capturing your command post. Whichever team captures more command posts (up to 3) in 15 minutes wins.
How to play Destruction: In this game type, both teams are attacking
and defending. Your goal is to call in three airstrikes on the command post (once again, marked by a yellow icon on your mini-map). Once you arrive at the command post, you or a teammate needs to hold
to call in the airstrike. Then your team must defend the command post from the enemies until the airstrike arrives. Remember, the enemy has the same objective here, so if the enemy holds the command post, you must take it back. Once a team's score reaches 350, the first airstrike will be called, second at 700, then game over at 1,000. Whichever teams reaches 1,000 points first wins.
