The Veteran Difficulty of Advanced Warfare must be the easiest in the series so I would recommend playing on Veteran difficulty for your first playthrough if you want to complete all the achievements and intels in a single playthrough. You can collect the missed intel or any mission specific achievement through the mission select option.

These achievements will unlock naturally as you complete the campaign.

Power Changes Everything
Completely upgrade your Exo.


Most probably by the end of the campaign you wont have enough points to fully upgrade your Exo suit, you can replay missions to complete the remaining challenges but you need to complete the mission before quitting to save progress on those challenges. Best mission to grind the challenges is the mission "Atlas" during the grenade training section, you can rack up the grenade kills and kills very quickly.

Can be done on the first mission near the end with the aircraft. Find a car door and detach it with cn_X.Try get real close to the enemy to make sure you get the kill and press cn_RS to throw it.

Some of these achievements can be done be done on other missions as well but i have put them on the specific mission where they can most easily be done.

MISSION 1:
Not On My Watch
Prevent the walking tank from being destroyed by the Drone Swarm in "Induction."


In the first mission when you get into the tank defend it from getting destroyed by the swarms, pretty easy ach.




MISSION 2:
Deadeye
Score "excellent" in the shooting range in "Atlas."


You will need to get "Excellent" ratings on the two training ranges. For the shooting range, it is important to always aim for the head (+100) of the red enemies, and never hit the blue enemies.



Grenadier
Score "excellent" in the grenade range in "Atlas."


Just keep spamming the smart grenades to get 2000 score THE HIGHEST SCORE on the leaderboards. If you run out of the smart grenades (lethal grenades) just walk in-front of one of the grenade stands. What I do is walk a little to the left and a little to the right and it refills it.


Fly Swatter
Knock 25 Drones out of the sky with EMP grenades.


Can be done on other missions as well cumulatively but this is a very good spot to grind the kills in the grenade training area.



This is also a very good spot to Grind the Kills and especially the Grenade kill challenges for upgrading Exo suit.


MISSION 3:
Look Both Ways
Kill all the KVA in the traffic section without damaging a civilian vehicle in "Traffic."


After you take out the armored truck in the small market, you will climb over a wall and come to the traffic section. You can cross the street and skip the enemies in the middle altogether. Take out all the enemies on the other side and try not to aim towards the street so you don't hit any vehicles. If you hit a vehicle by accident, reload the last checkpoint and you will still be able to get this one.




MISSION 4:
Riot Control
Kill 20 enemies while linked to the Mobile Cover Drone.


Immediately after you zip line from your helicopter at the beginning pf the mission there will be a Mobile Cover Drone available, just past the buildings and on your right. It looks like a big plastic shield. Pick it up with X and you will be able to shoot while using LT trigger to aim, and toss grenades through it like normal. Hang back so enemies will keep spawning and you will get your kills.




Fire and Forget
Kill 10 enemies with the Mobile Turret missiles in "Fission."


Near the beginning of the mission, you're teammate will notify you of the Mobile Defense Turret. Quickly go up to it and enter it. It has two different fire modes, but for the achievement/trophy, you want to use the bumper to "mark" enemies, and then let go for the homing missiles to kill the enemies.




3 Achievements can be done on the next section, when your teammate opens a door of the nuclear reactor and you enter a large battle area.



Threat Detected
Paint 10 enemies with a single threat grenade.


Just throw the threat grenade after entering the area as there will be large number of enemies present.

Never Saw it Coming
Boost jump, dash forward, then air stomp on an enemy.


Run up close to enemies double Jump then dash, then press cn_B to slam down.

MISSION 5
Wheelman
Finish the hoverbike sequence without hitting walls or obstacles or taking damage in "Aftermath"

At the end of Aftermath you will have to escape on the Hoverbike. You are not allowed to take any damage and you can't hit any obstacles or walls. If you hit anything, immediately reload the last checkpoint so you can try again. You can make a backup of save when you get on the bike if you get accidental checkpoints after getting hit.


MISSION 6
Sitting Ducks
Kill 3 enemies with one shot of the Sniper Drone in "Manhunt."


As soon as you gain control of your drone, mark your target, then go left and descend as low as you can go. You'll notice a group of 3 enemies very close to each other. You'll need to line two of them up with the one guard that is further away. The two far guards will line up perfectly, but there is one that moves around a little, and you will have to wait for him to walk in front of the others. The bullet must go through the head of the first one in order for it to travel all the way to the third guy.




MISSION 8
Party Crasher
Kill 20 enemies with the Grappling Hook in "Sentinel."


This achievement is a little tricky but not too bad if you are stealthy and play on a lower difficulty. One you reach the Sentinel HQ, you're teammate will teach you how to tag enemies, how to whistle and how to preform stealth kills using your grappling hook.




MISSION 9
Where Are You Going
Stop an AST with an EMP grenade.


This achievement can be done in other missions as well where the AST appears, select the EMP grenades by cycling through the non-lethal grenades and throw it in the enemy.




MISSION 10
Restricted Airspace
EMP 10 enemy aircraft out of the sky with the hovertank in "Bio Lab."


At the very end of the mission, you will enter a hovertank, and eventually make your way out of the base where enemy aircraft will begin to appear, both small and large helicopters. At this point, you will have to keep your eye in the sky, and listen to your allies who will say "Warbird Incoming!" when they are near. If you see one, make sure you switch to your EMP, and hit it.

MISSION 12
When you get to the large hanger section in the ship, you can do 2 achievements there.

Man Overboard!
Melee an enemy so they fly off the side of the ship in "Armada."

MISSION 13
Flying Ace
Shoot down 10 enemies with machine guns in "Throttle."


This achievement opportunity takes place right at the very beginning of the level, so you can always try again from the main menu if you have problems. The easiest way to get this is just to hold down your machine guns, and DO NOT use your missiles. You will have to aim at enemy ships which will show up as red diamonds on your HUD.




MISSION 14
Heavy Handed
Go through 20 gun drops in one-armed combat in "Captured."


All you need to do is carry 20 different weapons during the mission! Go through the mission as normal, but every time you get a kill, go to that person's body and pick up there weapon. Do this a total of 20 times, and the achievement will unlock!
