Best done in a boosting session. I don't think I've ever seen a Team Mission game during a search, anyway. Pick a small map and set it to 5 Zones, 5 individual respawns. Have a team of 2 against the rest of your boosting partners. You can plant 3 charges each match and then you have to run back to the extraction zone to win. To plant the charge, hit the Y button when standing in the middle of one of the boxes created by flares placed on the ground.
The person on your team not planting charges can kill the enemy team for progress toward the "Team MVP", "Team All Star", "Dangerous", "Lethal", and / or "Ruthless" achievements. When one person finishes the achievement, just rotate to the next person, rinse and repeat. Piece of cake.
