Killed 2 vehicles at once with the Target Locator during the 3rd mission.
During the Oni: Sword Base mission, you will come to the Target Locator and will then be face to face with two Wraiths. Try to get them together in one shot by making sure they are both within the red circle that appears on the ground. If you miss the two Wraiths, you can reload Rally Point Alpha or keep going where you will face a couple of Ghosts later on in the mission and try to get them together.

Destroyed the Corvette's engines & escort in under 3 minutes in the 6th mission on Heroic or harder.
During the space battle, after docking and getting loaded up, you will head back out to your Sabre and need to take out a Corvette. To get this Achievement, when the Corvette appears, head to the rear of it a good distance until you are told to take out the engines. Immediately head to the engines once they are highlighted and switch to missiles to take them out. You should be able to get all four in one pass. Once they are done, focus on the Banshees and the Seraphs. When the red arrows appear letting you know there are only a few left, narrow in on those.

Completed the 2nd mission on Normal or harder.
Once the introduction to the game is over, and you hop out of the falcon, you will be starting the second mission. There’s plenty of Achievements you can start racking up just on this mission alone. For this one achievement however, just reach the end of the mission.

Earned a Killing Spree in multiplayer Matchmaking.
In any multiplayer gametype, you will need to kill off 5 enemies without dying yourself. Easy enough, right? It’s certainly no airstrike but 5 GP is a good enough reward.

Killed the Elite Zealot before he escaped during the 5th mission.
Shortly after Rally Point Alpha starts, you will enter a mining facility and eventually come to a platform that looks over to another platform with a set of stairs that lead down to the ground. Before heading down the steps, look to the far side and the Zealot will be stalking around there. Use a Needler Rifle or DMR to take him out without getting close to him. If you do get close, he will keep running away from you and can eventually disappear all together robbing you of your achievement.
