Medal of Honor

Objective Raid is basically like Rush from Battlefield. You must detonate an objective and protect it for a set amount of time for it to explode. There is always 2 targets to detonate if you're on the attack team. If you're on the defending team you must make sure no one touches the objectives, and disarm them if they do.

This achievement only requires about 2 minutes of gameplay in Objective Raid for it to pop. Also if you continue to play for another cumulative of 2 hours, you will get the 2nd variant of this achievement.

You have to play the Objective Raid mode for at least 2 minutes for this achievement, simple and easy. Play another 2 hours and you'll get another achievement.

as it says there just select objective raid on the playlist and play you need to play for a couple of minutes and it will pop up if you play for two hours you will get another achivment to do with this playlist
